Kehinde, A. Roles of Retail Cooperative Marketing Strategies in Improving Marketing Efficiency of Small Agri-businesses in Ogun State, Nigeria. J Agron Technol Eng Manag 2021, 4(6), 664-673.
Marketing strategies are essential tools that improve the marketing efficiency of small agri- businesses. This paper examined the effects of marketing strategies on the marketing efficiency of select small-scale farms in Ogun State, Nigeria. Garri's Poultry Processing and Feeding Industries were the firms selected for this study. A two-step sampling procedure was used to select 100 respondents consisting of 50 respondents each in the Garri and poultry feed processing industries respectively. Data were analyzed using descriptive statistics, the marketing margin and efficiency model, and the ordinary least squares (OLS) model. The results revealed that product (40%) and pricing (26%) strategies were the most important marketing strategies used by the poultry feed industries, while pricing (28%) and location strategies (27%) were the most important marketing strategies employed by Garri's crafting Industries. The marketing margin and efficiency model revealed an average net marketing margin of ₦ 16.502 with an efficiency of 0.34 for the poultry feed industries. On the other hand, the average net marketing margin of Garri's processing industries was ₦ 119 278.91 with an efficiency of 3.4. Regression estimates revealed that market research and pricing strategies positively impacted the marketing efficiency of the poultry feed industries, while pricing, product and location strategies positively impacted the marketing efficiency of the poultry industries. The findings implied that price is a strong predictor of marketing efficiency for small-scale farms. It is necessary to apply the use of pricing strategies for the marketing of agro-industrial products, as it plays an important role in increasing the efficiency of the marketing system of feed processors and Garri.Article
Petrović, A.; Bursić, V.; Ivanović, I.; Marinković, D.; Stojanović, T.; Vuković, G.; Tanasković, S. Repellent Efficacy of Diethyltoluamide on Dermacentor marginatus Ticks (Acari: Ixodidae). J Agron Technol Eng Manag 2021, 4(6), 674-679.
Ticks can parasitize on a large number of hosts such as wild and domestic mammals, reptiles, birds, and humans. By changing hosts in order to take a blood meal, various pathogens could be transmitted from ticks to humans and animals. One of the preventive methods widely used to protect from tick bites is the use of substances with proven repellent effect. The aim of this study was to test DEET (diethyltoluamide) repellent efficacy as a function of time against Dermacentor marginatus ticks in laboratory conditions. The repellent efficacy was determined by ticks’ movement away or in the direction of the administrated preparation and expressed in percentages. Repellence decreased as a function of time, due to the evaporation of the active substance. DEET had 100% repellent efficacy on D. marginatus ticks in all replicates up to two hours after preparation application. After four hours it was 88.00%, and after eight hours 90.00% on average. In all five replicates the average repellent efficacy was 95.60%. Considering the confirmed ticks’ vector potential, studies on the repellent efficacy of certain substances are necessary, all with the aim to find widely available, highly efficient and economically justified substances, harmless to humans and animals.Cover of 2021, Volume 4, Issue 5 (October)

Adekunle, P.; Aigbavboa, C.; Akinradewo, O. Intervention of Biomimicry for Sustainable Construction: The use of Bio-Concrete. J Agron Technol Eng Manag 2021, 4(5), 641-648.
Biomimicry construction is defined as the science and art of solving human’s construction difficulties through emulating best biological proposition of nature. The benefits of biomimicry includes environmental and aesthetic factor. The use of materials such as bio-concrete increases environmental impacts exponentially. One of the major benefits of bio-concrete is that it is self-healing and it increases the effectiveness of any project design. Sustainable construction implies the use of materials that can be renewed and recycled, as well as reduce waste and energy consumption when building new edifice. To examine this intervention, this study employs a systematic literature review and site observation of how the use of bio-concrete can be adopted for the construction of buildings in the construction industry. Findings from this study revealed that biomimicry has helped to aid the development of sustainable construction. The use of bio-concrete which is a by-product of biomimicry will enable buildings to last for decades and also reduce maintenance cost. The usage of bio-concrete will also reduce concrete negative impact on the environment. The study concluded that the cost of producing bio-concrete is lesser than that of traditional abiotic reinforced concrete. By using bio-concrete for construction, assurance of a healthy environment is achievable.Article
Iromini, O.; Amujoyegbe, B.; Kehinde, A.; Bamire, A. Adoption of Cassava-Legume Intensification Options among Farmers in Innovation Platform of Humidtropics Programme in Southwestern Nigeria. J Agron Technol Eng Manag 2021, 4(4), 649-663.
Adoption of cassava-legume intercropping systems is fundamental to increasing the land productivity which increases profit margin of farmers. Therefore, this study investigated the factors influencing farmers’ adoption of a cassava-legume intensification options and the profitability of cassava legumes intensification options. Multi-stage sampling procedure was used to select 40 farmers from each of the Innovation platforms from the four Local Government Areas (LGAs) in Osun and Oyo states where the platforms are located to give a sample total of one hundred and sixty (160) respondents for the study. Data were analyzed using descriptive statistics, logit regression technique and farm budgetary analysis. The result showed that cassava-legume farming was dominated by male (78.8%). Majority (95%) was married and had formal education (78.1%). The results further showed that the estimated variable cost of ₦ 163,532.44 was incurred while total fixed cost was ₦ 11,079.86. Total revenue generated was ₦ 297,762.86, while net income and gross margin were ₦ 123,150.56 and ₦ 134,230.42. Binary logistic regression result revealed that years of education and farm size had positive relationship with farmers’ adoption of cassava-legume intensification options while revenue from cassava- legume intensification options was negatively related to farmers’ adoption of cassava-legume intensification options. The results showed that increase in the years of education and farm size will increase the likelihood of choosing cassava-legume among other intensification options while increase in revenue generated may not have effect in the likelihood of choosing cassava-legume among other intensification options. It was concluded that cassava cowpea intercrop was the most preferred by the farmers and was highly profitable. However, there is a need for an increase in the enlightenment of a cassava-legume intensification options through educational programmes, if the level of cassava-legume intercropping systems is to be increased in the study area.Cover of 2021, Volume 4, Issue 4 (August)

The aim of the research was to test the effect of application of plant growth regulators ascorbic acid (AsA), glycine betaine (GB) salicylic acid (SA), and water (H2O) on morphological characteristics of soybean plant (plant height, number of lateral branches, total number of nodules, number of fertile nodules, number of pods and weight of 1000 seeds). The field trial was conducted at an experimental field of the Institute of Field and Vegetable Crops in Novi Sad, Serbia in 2016–2017. The plant of the soybean cultivar ‘Sava’ was treated twice. The first treatment was done in the R1 reproductive stage and the second treatment was done in the R3 reproductive stage. Research has shown that in a favorable year (2016), the application of GB had the best effect on the number of lateral branches and fertile nodules. The use of SA achieved a significantly higher 1000 seed weight in relation to the control, but also water, regardless of the weather conditions during the vegetation. In 2016, compared to the control, the 1000 seeds weight increased by 10.36%, while in 2017 the effect was slightly higher by 12.92%. However, studies have shown that the use of growth regulators can also have a negative effect on the morphological characteristics of soybean plants, depending on the year and the weather conditions during the growing season.Article

Nepeta cataria, also known as catnip or catmint, is the most widespread and intensively studied species. The name catmint is derived from the strong attraction most cats have towards this species. Because of this, it is often used in pet toy industry as a safe attractant for cats. The main compounds responsible for this reaction in cats are nepetalactones. However, N. cataria var. citriodora or lemon catnip, an aromatic herb with a lemony-mint flavor, resembles true catnip, but is not attractive to cats. This variety is a good source for industrial production of citral and an attractive raw material for food industry and cooking; it is used as a dry spicy mixture for dessert dishes, in manufacturing of cheese, sausages, alcoholic beverages (liqueurs and vermouth) and soft drinks, vegetable and fruit canned food. N. cataria is cultivated for ornamental purposes, and because of the long flowering duration and large production of pollen and nectar it is very suitable for beekeeping. According to scientific reports, N. cataria possess antioxidant, hepatoprotective and antidiabetic activities, as well as sedative, antidepressant, spasmolytic, anti-nociceptive and anti-inflammatory activities. Experiments show that this plant influences sexual activity, and expresses anticancer properties. Antimicrobial activity against a number of bacteria is also noted, as well as repellent and insecticidal properties. Nematodidal and allelopathic effects are also noted.Cover of 2021, Volume 4, Issue 3 (June)

Đurić, K.; Prodanović, R.; Jahić, M. Experiences of European Union Countries in the Field of Agricultural Cooperatives. J Agron Technol Eng Manag 2021, 4(3), 583-590.
A cooperative is an autonomous association of persons voluntarily united to meet their common economic, social and cultural needs and desires through a jointly owned, democratically controlled enterprise. The key values on which authentic cooperatives are based were defined at the thirtieth congress of the International Cooperative Alliance in Manchester in 1995. The five key values of cooperatives are: self-help, democracy, equality, justice and solidarity.
The aim of the research is to review the experiences of European Union countries in the field of agricultural cooperatives. These experiences should serve as guidelines in creating a strategy for further development of agricultural cooperatives in the Republic of Serbia. The research focused on three topics in the field of agricultural cooperatives, namely: (1) market participation of cooperatives, (2) development policies and strategies, and (3) attitudes of young farmers about association. The research was conducted using comparative and historical methods, as well as methods of analysis, synthesis, induction and deduction. In the countries of the European Union, service and traffic are more represented, in relation to the production function of cooperatives. Also, all EU countries have integration processes in cooperatives at the vertical level, ie economic association and connection of cooperatives, which results in a reduction in the total number of cooperatives and an increase in their share in total turnover.Article
Songül, G.; Abdurrahman, K.; Songül, A. Factors Affecting the Farmers’ Decision-Making on Tractor Power Selection in Pistachio Farms: The Case of Siirt Province in Turkey. J Agron Technol Eng Manag 2021, 4(3), 591-597.
The selection of tractor power and agricultural equipment-machinery in agriculture is one of the most important issues in terms of mechanization planning and optimization. It is stated that the most important factors influencing the selection of tractors and agricultural machinery are land type, land size and crop production pattern. The main purpose of this study was to determine the major factors affecting tractor power selection in pistachio production farms in Siirt province in the Southeast Anatolia Region of Turkey. Study data were obtained from the 69-tractor owned pistachio farms using questionnaires during the face-to-face interviews in 2019. Descriptive statistical methods and multiple regression analysis with the least squares estimation procedure was used to determine the tractor power level and the factors affecting the selection of tractor power. Data analysis revealed that farmer age, the number of parcels, the soil structure had significant effect on the selection of tractor power as the effect of education level, the share of rented land in total farmland, and land slope were marginally significant. However, the ratio of irrigated land and pistachio acreage in total farmland and stoniness was not effective.Article
Abdullah, A.M.; Karuna, B.; Shah, S.; Abdul, K. Plant Traits Associated with Stagnant Flooding Tolerance in Rice (Oryza sativa L.). J Agron Technol Eng Manag 2021, 4(3), 598-612.
Stagnant flooding (SF) causes severe damage to modern rice varieties. This study was designed to evaluate morpho-physiological traits associated with tolerance of rice under SF. Ten aman rice varieties were tested under control and SF conditions. In SF treatment, 2-3 cm water depth was maintained upto 10 days after transplanting (DAT), than water depth increased gradually upto 50 cm that was maintained for 14 days. Although plants were not fully submerged, the yield was reduced by 25% across genotypes compared with those grown under control condition. This reduction was mainly attributed to the reduction in biomass caused by water height that reduced light interception under water. Stagnant flooding also affect chlorophyll content, spikelet and panicle production. The panicle number per unit area reduced by 55 % because of reduced tillering. Shoot elongation rate kept pace with rising floodwater and biomass production. Shoot elongation rate strongly and positively correlated with relative grain yield under SF. Principle component analysis suggest that to dry matter production and shoot elongation were the key determinant of SF tolerance in rice. Fine-tuning for optimum dry matter production and shoot elongation with rising floodwater is, therefore, a priority for future work.Cover of 2021, Volume 4, Issue 2 (April)

Aćimović, M. Essential Oils: Inhalation Aromatherapy – A Comprehensive Review. J Agron Technol Eng Manag 2021, 4(2), 547-557.
In recent years, there has been an increasing interest in the aromatherapy, a branch of phytotherapy, utilizing essential oils for the health maintenance. Essential oils are mainly applied through inhalation (through the respiratory system or olfactory nerves), through topical absorption (through skin) or through ingestion (digestive system). The essential oils are mixtures of many organic compounds, and their biological activity and fragrance are conditioned by their chemical composition. According to the aroma they can be classified into several groups: citrus, herbaceous, camphorous, floral, woody, earthy, minty and spicy. This paper reports a literature relating to the use of essential oils in inhalation aromatherapy. However, this type of aromatherapy does not cure major illnesses but it is effective at relaxation and stress relief, mood enhancement, balance and well-being, relief of minor discomforts and boosting the immune, respiratory and circulatory systems.Article
Tamirat, N. Adoption of Chemical Fertilizer Technology and Household Food Security, in Southern Ethiopia, in Case of Soro District in Hadiya Zone. J Agron Technol Eng Manag 2021, 4(2), 558-576.
Adoption of chemical fertilizer technologies is a prerequisite for achieving sustainable agricultural development. However, the link between chemical fertilizer technology adoption decision and food security remains poorly understood due to lack of comprehensive measures of food security. Therefore, this study attempts to investigate the factors affecting chemical fertilizer technology adoption decision, intensity of employing and its impact on the food security in Soro district, southern Ethiopia. A cross – sectional field survey was conducted among 382 cereal crop growers in Soro district in 2019 cropping season. Descriptive statistics and econometric methods such as probit regression, Heckman two stage and propensity score matching was developed for the data analysis. The results of probit regression revealed that the technology participant was significantly affected by size of family, education, family labor force, livestock holding, credit service, extension service, information, distance to market, distance to road and non-farm activity. Intensity of the technology significantly influenced by sex, size of family, family labor force, educational, marital status, membership to cooperative, extension service, access to credit and livestock holding. The findings suggest that the role of technology adoption at farm level due to higher yield and income could translate in to reduced poverty. Rural development office, extension office, and another concern body should give an important attention to adoption decision which is base for enhancing yield. Expansion in the level of adoption would consequently improve welfare economy.Article
Lika, E. Sustainable Rural Development in Albania Through Agriculture and Livestock: Challenges in the European Union Perspective. J Agron Technol Eng Manag 2021, 4(2), 577-582.
Albania's agricultural and food sector has shown remarkable resilience and adaptability over the last decades to a changing technological, economic, and social environment. This adjustment took place within a supportive policy setting that contributed to altering this long-term process. Whereas the agri-food sector still represents today an essential component of the Albanian economy, it has also shown critical importance for the environment and landscape in contributing over the centuries to creating and maintaining a variety of valuable semi-natural habitats to shape the majority of Albanian's landscapes. During the last two decades, Albania's agriculture sector passes through changes manifested through its modernization and a gradual increase in productivity. From 1995 productivity doubled and now amounts to around 3.500 USD per worker in the industry. Although it is a positive tendency, agriculture productivity is still five times less than in Greece, 15 times less than in Austria – two countries with several smaller farmers and share of extensive agriculture. These clearly show the development potential of the agriculture sector.Cover of 2021, Volume 4, Issue 1 (February)

An experiment was conducted to investigate chili pepper's effect in broiler nutrition on productive performances and blood lipid profile. For biological research, three treatments with a total of 450 broilers were formed within four replicates. Control treatment (CON) of chickens were fed with a standard feed mixture, while the experimental treatments were fed with the same mixture only with the addition of two levels of chili pepper 0.5 (CP-0.5) and 1.0% (CP-1.0). The addition of chili pepper in the amount of 0.5% has led to the highest final body weight of chickens (2460.6 g), followed by the addition of 1.0% (2442.4 g) with significant differences (p<0.05) compared to a control treatment (2075.8 g). The lowest amounts of triglycerides, total cholesterol, low-density lipoprotein (LDL), and non-high-density lipoprotein (non-HDL) were recorded in broilers in treatments with chili pepper with statistically significant (p<0.05) differences compared to a control treatment. The highest share of high-density lipoprotein (HDL) with statistical significance (p<0.05) was also determined in chili pepper treatments. Based on the obtained results, it can be concluded that the addition of chili pepper in broiler chicken nutrition has positive effects on production performances and in the improvement of chicken blood lipid profile.Cover of 2020, Volume 3, Issue 6 (December)

The emergence of new infectious plant diseases is driven by anthropogenic and environmental change, including trade, land use, and climate changes. The movement of infected plant material through trade in plant products, germplasm, grafts, and live plants has been recognized as the most significant contributing factor to the emergence of new plant diseases. Alternaria spp. are ubiquitous fungi. They are present in the human and animals' environment, being commonly found in environmental dust samples and air conditioning systems, while spore traps often show evidence of Alternaria dispersal. Alternaria spp. have even been shown to be associated with insects, having been isolated from the backs of cockroaches. Little work has been performed to investigate the saprotrophic lifestyle of Alternaria spp., which probably accounts for the majority of Alternaria species in nature. Alternaria spp. can persist on low nutrient media, suggesting that they can complete their lifecycle in poor nutrient environments. This review aims to present the lifestyle of ascomycete fungi such as Alternaria spp. and show their characterization as major feed grains pathogens in agricultural feed production.p>Review

The precision and efficiency of phytosanitary regulatory pursuits are conditional upon correct recognition of solitary confinement material, which in turn is reliant upon an exact taxonomic structure. Traditional disease diagnosis methods include the study of indicators on the host, isolation of fungi in suitable culture media, and ascertaining sexual and asexual edifices’ attributes along with spores used for the taxonomic classification. Attainment of components allowing pathogenicity on hosts has been indicated to have led the conversion in Alternaria alternata from a saprophytic to a plant pathogenic lifestyle. These elements are described as being “host-specific” or “host-selective” because they provide specific pathogenicity to a particular host or range of hosts. Barcoding uses a set of primers with broad specificity to magnify genetic regions typically 500-800 bp in length. Cytochrome oxidase subunit 1 is the animal barcoding locus and has been commonly used in fungi. Phylogenetic examinations have endeavored to define whether A. alternata pathotypes containing specific toxin genes are different phylogenetic taxa, and three descriptions can be deemed for the allotment of pathotypes all through the Alternaria phylogeny. Based on the above, this review aimed to present the molecular characterization of Alternaria spp. and toxin in isolated genes.Article

The number of plants per unit area has a great influence on soybean yield. The achieved composition depends primarily on the quality of the seeds, but also on the quality of soil preparation, meteorological conditions, the correctness of the seeder and the depth of sowing. In soybean production, it often happens that the pre-sowing preparation is done immediately before sowing, the sowing layer of the soil does not settle enough, and the sowing is done at a greater depth than optimal. Due to too deep sowing, germination and germination of soybean plants is difficult, the composition is thinned, and the achieved yield is reduced. Too shallow sowing also often occurs due to inadequate tillage or sowing to uneven depths. If the surface layer of the soil dries out after sowing, the seedlings will deteriorate, the composition will thin out and the soybean yield will decrease. The aim of this research is to consider the optimal, shallow, and deep sowing of soybean seeds on the number of plants per unit area, as a condition for achieving maximum soybean yield. By sowing to a depth of 3 to 5 cm in 2017 and 3 to 6 cm in 2017, a set of plants over 400,000 ha-1 was achieved, while with increasing or decreasing sowing depth, the number of sprouted plants significantly decreased.Cover of 2020, Volume 3, Issue 5 (October)

Bošković, J. Influence of Genetic Variability of Grapes to Produce High-Quality Wines. J Agron Technol Eng Manag 2020, 3(5), 483-488.
Grapevine is one of the most important fruit crops economically and is widely grown all over the world. Most of the grapevine fruits produced is processed into wine. Other than that, significant portions have also been used for fresh consumption, dried or processed into juice. The objectives of grapevine breeding vary based on the way it is used and they can be specific to the region in which it is grown. However, most of the time the end goal of breeding programs is to combine high yield and high fruit quality with better resistance to various diseases, and improved adaptation to different environments. Desirable traits such these can be exploited from the vast genetic resources of the Vitis genus. Methods like conventional breeding, mutation and polyploid breeding, and biotechnological approaches have been used to incorporate useful traits. Combining these methods will allow breeders to meet the growing demands for novel grapevine varieties and to produce high-quality wines.Review

The aim of this paper is to present the state of wine production and business of wineries in the Republic of Serbia, in order to create a set of measures to strengthen the capacity of the wine sector in the function of rural development. The results of the research show that viticulture production in the Republic of Serbia is poorly developed. These are modest areas and yields, with the absence of the use of modern knowledge and technologies in production. The wine industry has seen progress in the last two decades, but the situation is still unsatisfactory. In order to strengthen the capacity of the wine sector, it is necessary to focus on modernizing processing technology, branding, differentiation, new investments, education, association of winemakers, simplification of administrative procedures, applying for EU funds, increasing incentives, promotion and creating a stimulating business climate. Without stronger state support, no significant growth in the competitiveness of the wine industry can be expected. Since the number of wineries in the Republic of Serbia has recently increased, it is to be expected that the production of grapes and wine, as well as exports, will increase, and thus achieve significantly greater economic-ecological-social effects.Cover of 2020, Volume 3, Issue 4 (August)

The aim of this paper was to examine the influence of electrostatic field on the quality parameter of unprimed and primed soybean seeds. The experiment was conducted at the Institute of Field and Vegetable Crops in Novi Sad on soybean seeds of NS Blackstar variety. Seeds were exposed to different values of electrical voltage: 0 V (control), 3 V, 6 V and 9 V. Before exposure, the seeds were primed in water for 0, 1, 2 and 3 hours. Results of the conducted experiment showed that the influence of the electrostatic field on the unprimed soybean seeds depended on the strength of applied electrical voltage to conducting electrodes. By applying electrical voltage of 6 V to conducting electrodes, germination energy was increased by 10%, while germination was increased by 5% compared to control. However, the application of electrical voltage of 3 V and 9 V, showed that germination energy was significantly decreased, 19% and 21%, respectively. On primed soybean seeds, the use of electrostatic field led to a significant reduction in seed quality, regardless of the time of primed. The results also showed that the treatment that significantly increased the germination energy and germination of unprimed seeds, was treatment with applied electrical voltage of 6 V. This treatment had a significant effect on the germination rate parameter, but only on MGT and T50. In other treatments, applied electrical voltage did not affect or prolong the time of seed germination.Cover of 2020, Volume 3, Issue 3 (June)

Tanacetum vulgare L. (syn. Chrysanthemum vulgare L.) commonly known as tansy, is a perennial herb of the Asteraceae family, native to temperate Europe and Asia, where it grows along roadsides, hedgerows and waste places. It was introduced into North America for medicinal and horticultural purposes and now grows wild throughout many USA states. It has two varieties: var. vulgare (distributed in N Europe and N America, however in Corsica, Sardinia and Sicily ssp. siculum grows, in some cases reported as a separate species) and var. boreale (distributed in Russia, China, N Korea and Japan). Aerial plant parts contain essential oil divided into chemotypes, and the environmental adaptability of the plants can be assumed from essential oil contents. T. vulgare is also rich in phenolic acids, flavonoids and their derivatives which contribute to the pharmacological actions of the plant.Review

Plants, particularly medicinal and aromatic species, and plant-derived compounds have been used for centuries in human and veterinary medicine, but nowadays they have increasingly important role in agro-food industry. They present a rich source of bioactive compounds with a wide range of applications that answer to/coup with certain emerging challenges. The most important are growing demands for food safety and concern about human health and environmental pollution that altogether impose the need for more intensive use of plants and their compounds in food industry and agricultural production. This is a reason why, in recent decades, more intensive research has been carried out related to new, bio-rational and specific trends in agro-food industry. Cymbopogon citratus Stapf., lemongrass, is one of medicinal plant species with large application potential in different areas. This review provides an insight into current research and potential applications of C. citratus in food and feed technology, plant protection (as repellent, biofungicide, bioinsecticide, bioherbicide, etc.) and in veterinary medicine purposes. The most comprehensive research on biological activity of lemongrass has been carried out in the field of medicine, entomology and plant protection. However, the information on allelopathic effects and agro-food application is scarce and insufficient, requiring additional research.Review

In recent years, S deficiency has been described as a limiting factor for crop production in most regions of the world. It has been determined that S deficiency decreases the quality and yield of plant tissue. Therefore, it is known that there is a linear relationship between the oil contents of the plants and the sulfur contents. Brassica napus L. (Cruciferae), is one of the cultivated medicinal food and oil plants. So, it is important to determine the most appropriate sulfur dose in the plant. This study aimed to determine the effect of different dosages of sulfur on the fatty oil with some agronomic properties in the rapeseed. This work, which was held in 2011 and 2012, was carried out in the experimental fields of the Faculty of Agriculture of the Dicle University. In the research, two cultivars of rapeseed (Licord and Licrown) and 6 of sulfur doses (0 kg/ha, 30 kg/ha, 60 kg/ha, 90 kg/ha, 120 kg/ha and 150 kg/ha) were applied. The highest yield in terms of seed yield was obtained from the 15 kg/ha sulfur dose in Licrown cv. range with 294 kg/ha in the second year, while the highest fatty oil content was obtained in 0 kg/ha in Licrown cv. with 45.7% and 45.4% in both years.Article

Precision agriculture (PA), defined as spatial/temporal management of agricultural practices, requires adequate knowledge about crop growth and development phenology, requirements, and the parameters affecting them. Despite the importance of temporal management of agricultural practices, it has not been dealt with in most of the reviewed literature. In this paper, temporal management of agricultural practices in precision agriculture is discussed and crop growth simulation models are suggested as robust tools to schedule the agricultural practices. Crop Growth Models (CGMs), by scheduling the crop production activities can help producers to temporarily manage the inputs, while the efficiency of production would be enhanced. Some of the well-known crop growth models are introduced as tools for simulating the required production inputs during the growth period. Finally, time-specific management (TSM) of agricultural practices base on these models is suggested as the next generation of PA.Cover of 2019, Volume 2, Issue 6 (December)

Journal of Agronomy, Technology and Engineering Management, 2(6): 335-343.
The main objective of this research was to determine the effects of dietary essential oils mixture of thyme (Thymus vulgaris), oregano (Origanum vulgare) and rosemary (Rosmarinus officinalis), on breast and thigh with drumstick composition, technological and sensory quality of poultry meat. In order to realize the tasks set, biological trial was carried out with 840 Ross 308 strain broiler chickens equally distributed into three dietary treatments. The diets were supplemented with no essential oils mixture (T1), essential oils mixture at 0.05% (T2) and essential oils mixture at 0.10% (T3). On the basis of gained results, it can be concluded that in breast and thigh with drumstick of experimental treatments protein content was statistically significantly (p<0.05) higher compared to control treatment. Additionally, in thigh with drumstick fat content was significantly lower in treatments T2 and T3 relative to those reared on control (without supplementation) diet, while in breast this difference was only numerically different. Ca content, hydroxyproline and collagen contents, as well as relative content of connective tissue proteins were also improved in treatments with addition of essential oils mixture. Based on the technological property parameters of meat such as pH, colour, water holding capacity and cook loss it is proved that essential oils mixture improved breast and thigh with drumstick quality. Moreover, regarding the sensory quality attributes a higher overall score for the breast and thigh with drumstick supplemented with essential oils mixture than for those of the control group was recorded. The findings obtained in this study highlight the potential of phytogenic feed additives as a tool to improve poultry meat quality and meet consumer expectations.Review paper

Journal of Agronomy, Technology and Engineering Management, 2(6): 344-360.
The genus Cymbopogon (Greek words 'kymbe' meaning boat and 'pogon' meaning beard), commonly known as lemongrass, belongs to the Poaceae family. It comprises a large number species, but only two have economic importance as cultivated plants: C. citratus and C. flexuosus. However, C. citratus is more resistant to drought and low temperatures and because of that can be cultivated over large areas therefore it is commercially more important. C. citratus leaves are widely used as a lemon flavor ingredient in herbal teas, prepared either by decoction or infusion, or in finished herbal products such as capsules, tablets and creams. Even though essential oils are known for being used for fragrance and as an important ingredient in Asian cuisine, they are also used in other industries (pharmaceutical and cosmetic) due to their bioactive compounds that show various therapeutic effects. The chemical composition of C. citratus essential oil varies widely depending on genetic diversity, habitat and agronomic treatment of the culture, as well as on the part of the plant, maturity stage and extraction method. However, the essential oil of C. citratus mainly consists of the citral, which is a mixture of two isomeric acyclic monoterpene aldehides: geranial (trans-citral) and neral (cis-citral). C. citratus possesses good antibacterial activity, it could be used as alternative treatment for enteric fever, to cure infectious diseases related to the respiratory system, as well as for oral hygiene, it helps by removing bacteria from the oral cavity and prevents teeth and gum diseases such as peridontitis, plaque and gingivitis. Furthermore, C. citratus showed high contents of total phenolic and total flavonoids, as well as high free radical scavenging capacity with potential as an antioxidant. C. citratus shows good antiinflamatory, anti-diabetic, hypolipidemic, renoprotective and cardioprotective, as well as anticancer activities. Apart from this, C. citratus possesses vasorelaxant, sedative and antitusive potential. Furthermore, the compound citral is used in perfume industry as well as for cleaning wounds and treatment of skin diseases in forms of gels, or functional paper microencapsulated with essential oil, which can be used for hand hygiene.Cover of 2019, Volume 2, Issue 5 (October)

Experiment was conducted to investigate the effect of chili pepper in broiler nutrition on productive performances and blood lipid profile. For biological research three treatments with the total of 450 broilers were formed, within four replicates. Control treatment (C) of chickens were fed with mixture based on corn flour and soybean meal of standard composition and quality, while the experimental treatments were fed with the same mixture only with addition of two levels of chili pepper 0.5 (CP-0.5) and 1.0 g/100g (CP-1.0). Addition of chili pepper in the amount of 0.5 g/100g has led to the highest final body weight of chickens (2460.6 g), followed by the addition of 1.0 g/100g (2442.4 g) with significant differences (p<0.05) compared to a control treatment (2075.8 g). The lowest amounts of triglycerides, total cholesterol, low density lipoprotein (LDL) and non-high density lipoprotein (non HDL) was recorded in broilers in treatments with chili with statistically significant (p<0.05) differences compared to a control treatment. The highest share of high density lipoprotein (HDL) with statistical significance (p<0.05) was determined also in chili pepper treatments. Based on the obtained results, it can be concluded that the addition of chili pepper in broiler chicken nutrition has positive effects on production performances and in improvement of chicken blood lipid profile.Review paper

Journal of Agronomy, Technology and Engineering Management, 2(5): 325-334.
Coccidiosis is well known as an expensive, parasitic disease for the poultry industry worldwide. The disease causes real economic losses by causing poor growth and feed efficiency in broilers even leading to high mortality. Consequently, large amounts of money are being spent on vaccination and the inclusion of anticoccidial drugs into diets. In recent years, the development of resistance to coccidiostats, elevated costs of systematic vaccination and increasing consumer demand for natural food products has fuelled the development of natural, plant-based alternatives for coccidial control in poultry farming. The anticoccidial properties of numerous natural products such as Ageratum conyzoides extract, Polygonum bistorta, Agele marmelos, Artemisia sieberi, Artemisia absinthium, Azadirachta indica, Artemisia annua and Aloa vera based supplements have been reported. This article summarises the experimental knowledge relating to the efficacy, possible modes of action and different aspects of application of medicinal plant supplements as feed additives for the treatment of poultry diseases, especially coccidiosis.Cover of 2019, Volume 2, Special Issue 1 (September)

Application technologies are considered genetic engineering in agriculture with the introduction of genetically modified (GM) plants are constantly creating new opportunities to increase crop production and to solve problems in agriculture, such as diseases, pests, weeds, abiotic stresses, and nutritional limitations. These are formed, and the plants having new properties that enable their use in pharmaceutical manufacturing. As the GM plant introductions to various locations characterized by a variety of ecosystems, types of agriculture, biodiversity and agriculturally practice, it is necessary to the scientific understanding of the effects of growing GM plants on the environment, which will provide security and environmental sustainability. The most important research she focused on the invasiveness of the GM plant, vertical and horizontal gene transfer, the impact on biological diversity and on other products. These tests are very complex multi, inter and transdisciplinary. This article discusses some of the most important problems related to the application of the technology of genetic engineering in agriculture and the introduction of GM plants into the environment, such as plant protection, ecological effects of horizontal gene transfer, biodiversity, stress, the effects of land, etc. There is a clear need to further investigate the size and scope of the risk spreading of transgenic plants. In assessing the interrelation of GM plants and existing varieties, more detailed knowledge of the development of GM plants will provide a clearer, more reliable and precise directed activity in plant sciences.Original research paper

Journal of Agronomy, Technology and Engineering Management, 2(4): 312-317.
From antiquity, essential oils of medical plants and their derivatives have being used for flavoring foods and beverages and for medication. These additives have been usefully used in animal nutrition for the improvement of health and animal wellbeing since they have high antimicrobial and antioxidant activities. In the present study, the effect of the pelleting process on essential oil composition and stability was investigated, since they are very unstable during thermal processing which is widely used these days in feedstuff production. The composition of essential oil obtained by hydrodistillation from the plant Origanum vulgare, which was added into feed for broilers in the concentration of 2 g/kg, was analyzed by GC/FID before and after the pelleting process. After the pelleting of feed, the essential oil was also isolated from the animal diet by hydrodistillation. Analysis of essential oils obtained before and after the pelleting process showed some quantitative differences. Oregano essential oil was characterized by the presence of thymol (19.9%) and carvacrol (61.8%) at the beginning of the experiment. After the pelleting process, the concentration of thymol and carvacrol amounted to 15.3% and 50.4%, respectively. It was concluded that the pelleting process had a significant effect on thymol and carvacrol stability in animal feed, i.e. on reducing their initial contents in animal feed.Cover of 2019, Volume 2, Issue 3 (June)

The research was carried out in the area of the AP Vojvodina with the aim of obtaining data on the degree of application of innovations in the beekeeping industry, as well as the potential and readiness of beekeepers to introduce new technologies such as smart hives, permanent satellites, and organic production systems. Total of 112 beekeepers was selected, randomly selected, where the sample was to be as representative as possible, that is, the spatial coverage was considered. The average age of beekeepers was 46 years with an average experience of 11.5 years. Three types of hives were identified (a hive with frames, a modern hive, and a smart hive). More than 60% of the respondents harvest honey annually, while about 30% of the respondents picked up between two to three times a year. Moreover, on average 21 and 24 kg of honey is collected from modern and smart hives, respectively. Classic hives provide a yield of honey on average 21.5 kg. There were differences in the yield of honey depending on the type of hive and the length of the beekeeping period, where more experienced beekeepers achieved somewhat better results. More than 90% of respondents prefer classic hives. Factors that affect the lack of use of modern hives are the lack of equipment (36.5%), followed by the quality and availability of wax (34%). In order to adopt and maintain modern technology of hives, the focus should be on education, equipment for honey production, as well as on the quality of wax and its availability.Review paper

In recent decades insecticides have entered into wide use in agricultural production. In addition to the positive effects such as increased yields, there was a far-reaching negative implications for biodiversity, agro-biodiversity, the environment and human health. Toxic chemical compounds, which are components of insecticides contaminating pollen and nectar, and thus have a negative impact on the bee population and their survival. Through bees insecticides are becoming an integral part of the bee products consumed by man. Insecticides weaken resistance of bees, encourage the emergence of diseases for example Nosema ceranae, and can lead to the collapse of the colony. Further contamination of ecosystems insecticides can jeopardize the whole economic and ecological system.Cover of 2019, Volume 2, Issue 2 (April)

Journal of Agronomy, Technology and Engineering Management, 2(2): 248-262.
The Objectives of this study were to determine the general (GCA) and specific (SCA) combining abilities and heterosis of some cotton genotypes for yield, its components and fiber traits using line × tester mating design. Thirteen parents (ten lines and three testers) along with their thirty F1 crosses were studied in randomized complete block Design (RCBD) with three replications during 2016 at Sakha Agriculture Research Station, Kafr El-Sheikh Governorate, Egypt. Based on line x tester analysis, the variances due to genotypes, parents, crosses and parent vs cross exhibited significant differences (p<0.01) for most yield, yield component and fiber traits. The variances due to GCA of lines and testers, and SCA of line x tester interactions were highly significant for most studied traits, indicating the importance of both additive and non-additive gene actions in controlling these traits. The proportional contribution of line × tester was higher than individual contribution of lines and testers for most studied traits. The estimates of GCA and SCA effects revealed that the parents and some crosses were having desirable and significantly GCA and SCA effects, respectively. High mean performances and desirable GCA effects values were observed of lines Pima S6, Suvin, G.90, Aust. 12 and tester C.B.58 for most investigated traits, hence these parents can be used for generating superior cotton hybrids Significant correlation coefficients (p<0.05 or p<0.01) in positive direction were obtained between all possible pairs of F1 hybrids mean, SCA and heterosis. The best values of mean performances, SCA effects and heterosis were found in the combinations Suvin × G.86 and Aus.12 × C.B.58 for most yield and yield components, and the G.90 × C.B.58 and G.95 × G.86 for fiber traits. These crosses are considered the promising crossed to be used in breeding programs for produce hybrid cotton and improvement for these traits in Egypt.Original research paper

Journal of Agronomy, Technology and Engineering Management, 2(1): 130-137.
Salmonella is one of the most important foodborne zoonotic pathogens, with significant health and economic impact in both humans and animals. The control of Salmonella in animal feedstuffs is important, principally to protect the human food chain from contamination by Salmonella derived from infected animals. Salmonella can reach into the animal feed by multiple ways and during all production stages. Main sources of contamination are fertilizers on the pasture/fields, ingredients, co-products, dust, wild animals and contaminated equipment. Thus, there is importance for implementation of strategies for preventing feed contamination with Salmonella, by minimizing dust, maximizing hygiene of space and processing equipment in feed mills and implementing control measures in each stage of feed production. Elimination of Salmonella refers to thermal treatment (pelleting, extrusion) or chemical treatment. Feed additives, such as organic acids, short- and medium-chain fatty acids, prebiotics, probiotics and, more recently, essential oils of plant origin, have the potential to reduce Salmonella levels when added to the feed. Therefore, the purpose of this review is to discuss the prevalence and prevention methods for the control of Salmonella in the feed industry.Review paper

Journal of Agronomy, Technology and Engineering Management, 2(1): 138-152.
Precision agriculture (PA), defined as spatial/temporal management of agricultural practices, requires adequate knowledge about crop growth and development phenology, requirements, and the parameters affecting them. Despite the importance of temporal management of agricultural practices, it has not been dealt with in most of the reviewed literature. In this paper, temporal management of agricultural practices in precision agriculture is discussed and crop growth simulation models are suggested as robust tools to schedule the agricultural practices. Crop Growth Models (CGMs), by scheduling the crop production activities can help producers to temporally manage the inputs, while the efficiency of production would be enhanced. Some of the well-known crop growth models are introduced as tools for simulating the required production inputs during the growth period. Finally, time-specific management (TSM) of agricultural practices base on these models is suggested as the next generation of PA.Review paper

Moldavian balm or Moldavian dragonhead (Dracocephalum moldavica L.) is native to temperate climate of Asia, but it was naturalized in Eastern and central Europe, North Africa, China and north-eastern United States. This plant with its citrus like flavor is extensively used as a spice and for composition of teas, because of neral and geranial as major constituents of essential oil. D. moldavica is used in food aromatization, perfumery, alcoholic drinks industry, soaps and detergents. Apart from being used as medicinal and spice plant, it is grown as a honey-bearing plant and cultivated in gardens and parks as an ornamental plant. Seed is a good source of fatty oil with spicy taste and aromatic odor, rich in unsaturated fatty acids, principally the linolenic and linoleic acids. This categorizes D. moldavica seed into the group of raw materials suitable for nutraceuticals, food supplements, and functional food applications. Furthermore, numerous investigations show that this plant possesses good antioxidative, antimicrobial and insecticidal activity. It is also used as antinociceptive, sedative, neuroprotective, as well as cardiotonic agents, and for treating chronic mountain sickness.Review paper

Journal of Agronomy, Technology and Engineering Management, 2(1): 168-177.
In the world where technology is upcoming very fast with the production of different chemicals such as acaricides, pesticides and etc., the real question is: Could essential oils, spices and herbs serve as natural solutions in constant struggle against chemically resistant drugs? The poultry red mite (Dermanyssus gallinae) is a growing epidemiological problem for the poultry industry that causes losses in the performance of laying hens and consequently major economic losses. It has been suggested that adding essential oils to laying hen diets may be an efficient and natural alternative to chemical repellents and acaricides for D. gallinae. Although some essential oils are effective repellents, their effectiveness usually lasts a short time, which is likely related to their volatile nature. The exact mechanism of the acaricidal effect of essential oils is not yet clear, but it is thought that some essential oils could inhibit D. gallinae cytochrome P450 and thus reduce detoxification of xenobiotics. However, most D. gallinae repellent activity appears to come from neurotoxic effects, blocking γ-aminobutyric acid neurons and reducing the ability of cells in the nervous system to form cyclic adenosine 3′,5′-monophosphate. To date, most studies have been conducted in vitro and there is a lack of information on the effect of essential oils on laying hen performance under the challenge of D. gallinae. The paper aims to review current knowledge of D. gallinae biology and the possibilities and significance of inclusion of selected essential oils into laying hens diet as a natural repellent of hematophagous predator.Review paper

The aim of the paper is to present the air quality, sources of pollution, as well as the process of its pollution in urban regions such as cities. Focus is aimed on the air quality of the city of Novi Sad located in Vojvodina with most important air pollutants such as SO2 and NO2, which represent sources of air pollution. Aim is also focusing on possible proposals of measures for improvement of air quality. In order to improve air quality, environmental protection and natural resources, as well as to prevent human health damage, measures must be taken to reduce air pollution. Most important measures are related to further research into air pollution and the creation of appropriate policies and strategies. Possible methods of reducing the negative impact of air have been identified and particularly prominent. Environmental policy includes air quality standards, cost benefit analysis, urban planning, and assessment of the impact of local projects on the environment. New measures are also being identified, which distance themselves from conventional solutions and a control approach in reducing air pollution. The problem of air pollution and implications alarms that it acts synergistically towards the realization of research and projects with a focus on a proposal of a set of new measures in the function of improving the quality of air and reducing pollution.Original research paper

In order to preserve fragile and sensitive aquatic ecosystems, such as Special Nature Reserve (SNR) “Obedska bara”, a monitoring protocol should be implemented, including the utilization of various bioindicators, biomonitors and biomarkers. Copepods and cladocerans, as a part of the freshwater zooplankton communities, prefer habitats with stabile and constant physical, chemical and biological parameters, and therefore could be used as the precise bioindicators. The aim of this study was to obtain copepod and cladoceran species diversity and abundance as valuable data, which could be further used as a sensitive and accurate model for the assessment of SNR „Obedska bara“ status. During the research period, five copepods and three cladocerans species were collected from two prospected localities: Cyclops vicinus, Acanthocyclops robustus, A. vernalis, Eucyclops serrulatus, Eudiaptomus gracilis, Daphnia magna, D. pulex and Bosmina longirostris. The most abundant species were C. vicinus and D. magna. The species diversity and population densities of freshwater crustaceans are correlated with the numerous abiotic and biotic factors. Although SNR “Obedska bara” belongs to the list of protected areas, it is still exposed to the strong anthropogenic influence.Original research paper

This paper presents the results of sea water and mussels meat quality investigation on three sites in Boka Kotorska Bay. Two sites are situated in inner part on shelfish farms (IBMK and COGI) and one close to open sea, Žanjice, is chosen as referent one. The sanitary quality on shellfish farms was satisfactory according the “Regulation on the classification and categorization of surface and ground water 02/07” on referent location and COGI shellfish farm. Low abundances of fecal indicator bacteria in water were recorded, indicating that no direct human contamination had occurred. Results on IBMK shellfish farm were periodically unsatisfactory according the Regulation 02/07. Obtained results present that the IBMK showed the highist value of E.coli (800 cfu/100ml) and Enterococi (350 cfu/100ml) in September 2015. Recorded phytoplankton data showed that microplankton and nanoplankton abundances reached values up to 105 cell/l. Diatoms was dominant group of phytoplankton and also reached values of 105 cells/L. Abundances of diatoms were similar at two farm sites with some maximal abundances on COGI in September 2016. The same is for abundance of dinoflagellates, similar values were noticed with maximal abundances on COGI site in April 2016. Sometimes this group prevailed on diatoms during spring/summer. Quantitative and qualitative analysis of bio-toxins in mussels tissue showed that all obtained results were below detection limits (LOD) what indicate good quality of farmed mussels, safety for use in human nutrition.Original research paper

Aim of this study was to investigate the effect of natural growth promoters such as garlic, black pepper and hot red pepper in broiler chicken nutrition on production performances and chicken carcass quality. At the beginning of the experiment, a total of 1200 one-day old Hubbard broilers were totally randomly distributed into eight dietary treatments with four replicates each. For nutrition of chicks three mixtures were used, starter, grower and finisher. Dietary mixtures in the experiments was as follows: T1 (Control diet), T2 (Garlic powder 0.5 g/100g), T3 (Garlic powder 1.0 g/100g), T4 (Black pepper powder 0.5 g/100g), T5 (Black pepper powder 1.0 g/100g), T6 (Hot red pepper 0.5 g/100g), T7 (Hot red pepper 1.0 g/100g) and T8 (Mixture of spices in ratio of 1:1:1 in total amount of 0.5 g/100g). Addition of spices significantly (p<0.05) influenced on production parameters and carcass quality of broiler chickens. The highest achieved body weight of chicken was in treatment T6 (2460.6 g) which was followed by treatment T7 (2442.4 g) with statistically significant differences (p<0.05) compared to other treatments. In carcass which was ready for roasting, highest yield was recorded in dietary treatment T7 (1829.8 g) which was statistically significant (p<0.05) higher compared to treatments T1 (1626.5 g), T3 (1710.7 g), T4 (1532.2 g) and T5 (1587.5 g), respectively. The primal cuts of the most economically important value such as drumsticks with thighs had the highest weights in treatments T7 (530.7 g), T6 (525.2 g), T2 (520.2 g) and T8 (497.1 g), with statistically significant differences (p<0.05) compared to treatments T4, T5 and T1 (438.5 g, 448.7 g and 461.1 g). It can be concluded that the addition of garlic, black pepper and hot red pepper in broiler chicken nutrition has positive effect on production performances and in improvement of chicken carcass quality which will be more acceptable by the consumers.Original research paper

The medicinal plants and herbs have been used for many years in the treatment and prevention of various diseases in animals and human beings. Nowadays, utilization of these medicinal plants is increasing. This article summarizes the experimental knowledge on efficacy, possible modes of action, and aspects of application of phytogenic products as feed additives for treatment pig and poultry diseases. Phytobiotics is a term used to describe plant-derived natural bioactive compounds, which affect animal growth and health, and is often applied to essential oils, botanicals, and extracts derived from herbal plants. Some phytobiotics are known to have antimicrobial or antiviral activities. Selected herbs, however, are known to possess natural antibacterial activity and other characteristics that could be useful in value-added animal protein production. This area of investigation has not received substantive examination because of the relatively low costs, proven effectiveness, and ready availability of synthetic growth-promoting antibacterial products. Herbs and spices have always been helpful to cure diseases. In modern animal nutrition, they are forgotten because of use of synthetic antimicrobial growth promoters (AGP). But due to the prohibition of most of AGP, plant extracts have gained interest in animal feed strategies. The risk of the presence of antibiotic residues in milk, meat, egg and their harmful effects on human health have led to their prohibition for use in animal feed in the European Union. Many plants also produce secondary metabolites such as phenolic compounds, essential oils and saponins. They act as antibacterial, antioxidant, anticarcinogenic, antifungal, analgesic, insecticidal, anticoccidial and growth promoters. Azadiracht indica, Zizyphus vulgaris, Ocimum gratissimum and Atlanta monophylla have the strong antibacterial activity, whereas ocimum plant has strong antioxidant, anticarcinogenic, antifungal, analgesic and antipyretic properties. Leaves of Azadirachta indica are used for feeding and reducing the parasitic load of animals. The fruit of Azadirachta indica and Artemisia annua also has the anticoccidial activity for poultry. These plant extracts compete with the synthetic drugs. Majority of medicinal plants do not have the residual effect, because have an approved application in human medicine and which can be added to animal feed for use in preventive and therapeutic treatment of different animal health disorders.Review paper

Clary sage (Salvia sclarea L.) is native to Southern Europe and is cultivated worldwide, as ornamental, as well as essential oil bearing plant. Clary sage is well known for its high value essential oil, widely used in perfumery. Besides, the oil possesses high biological activity and because of that is used against stress, tension, depression, insomnia, etc. However, traditionally clary sage oil was used an agent against gingivitis, stomatitis and aphthae. Apart of that, recent studies reported analgesic, anti-inflamatory, antimicrobial, antidiabetic and cytotoxic effects. Studies on clary sage seed fatty oil show that it is a good source of edible oil rich in omega 3-linoleic acid. Clary sage is also used in alcoholic beverages, as well as in tobacco industry. Novel investigations indicated that clary sage have great potential in agriculture because of phytoremediation, allelopathic and insecticidal properties.Review paper

Journal of Agronomy, Technology and Engineering Management, 1(1): 29-38.
Aim of this paper is to show antimicrobial, antifungal, antioxidant and acaricidal properties of tea tree (Melaleuca alternifolia). Tea tree exhibits wide spectrum of antimicrobial activity. Its mode of action against the Gram-negative bacterium Escherichia coli, the Gram-positive bacterium Staphylococcus aureus, and the yeast Candida albicans has been investigated using a range of different methods. As antimicrobial, tea tree possess high inhibitory antifungal activity because of its components such as terpinen-4-ol, α-terpineol, linalool, α-pinene, β-pinene, and β-myrcene followed by 1,8-cineole. Bioactive compounds such as α-terpinene, α-terpinolene, and γ-terpinene shows high antioxidant activity of tea tree. Also, tea tree with its components are known to possess bacteriostatic and germicidal properties and are used to cure infections of the skin and mucous membranes such as boils, abscesses and onychomycosis caused by Candida. Their apparent insecticidal and acaricidal properties have to date been tested on some human ectoparasites such as head lice and Sarcoptes scabiei, var. hominis, and in recent time tea tree extracts were used in research for controlling ticks (Ixodes ricinus) that are efficient vectors of pathogens.Review paper
BOGOEVA, I. (2018) Production of safety food by phytoremediation methods.
Journal of Agronomy, Technology and Engineering Management, 1(1): 39-44.
The production of pure and safety food, whether of plant or animal origin, requires a clean environment, for growing of plants, which serve as food for humans and livestock. The high development of the industry, as well as the use of many chemicals in the modern life and farming, are the main causes for the presence of toxic residues in nature and therefore – in the food. Among the main causes of soil and farmland pollution are heavy metals, pesticide residues and petroleum products. Modern environmental science is looking for ways to clean the soils from pollutants, which at the same time, to be ecologically and environmentally friendly. Traditional methods for cleaning the soil from different pollutants, such as excavation, etc., are very economically disadvantageous, but they also cause environmental damages. Because of the large economic costs, associated with the removal of soil contaminants through traditional physicochemical methods, this problem was overlooked for many years. Phytoremediation (mainly phytoextraction – absorption and concentration of environmental substances in the plant biomass) is a widespread and relatively new technology that uses plants to clean environmental pollutants by extracting them. This plant-based achievement is cost-effective and is due to the remarkable ability of plants to concentrate elements and compounds from the environment and to break down their molecules into their tissues. Using phytoremediation is possible to degrade, assimilate or detoxify toxic chemicals.Review paper

Journal of Agronomy, Technology and Engineering Management, 1(1): 45-51.
Different societies throughout human history have highlighted roses as a symbolic value and great cultural importance. Roses secondary purpose is the production of essential oils for the perfume and cosmetic industries, but they are widely used as garden ornamental plants and as cut flowers. Domestication of roses has a long and complex history, and the rose species have been hybridized across wide geographic areas such as Europe, Asia, and the Middle East. The domestication processes selected very important flower characters such as recurrent flowering, double flowers, petal colours, and fragrance. The molecular and genetic events that determine some of these flower characters cannot be studied using model species such as Arabidopsis thaliana, or at least only in a limited manner. Aim of this review was to approach and highlight development of genetic and genomic tools for roses, and then focus on recent advances that have helped understanding the molecular mechanisms of some rose floral traits.Review paper

Journal of Agronomy, Technology and Engineering Management, 1(1): 52-56.
Fish and fish meat are the final chain of aquatic food web and an important food source for human, while the water pollution is the burning issue all over the world. Aquatic ecosystems are frequently contaminated with different toxicants through anthropogenic activities, and some of them such as metals may be naturally present and essential in low concentration but toxic and harmful in higher concentrations. Not all chemical forms of pollutants are equally bioavailable and some pollutants can be accumulated in living organisms to a greater extent than others, there is a need to study the levels of pollutants in the organisms to be able to predict the environmental risk. Aim of this review paper is to present the influence of persistent organic pollutants and heavy metals and fish as one of the very important bio-indicator and biological marker for environmental pollution, as well as damage effects of these toxic materials to fish organs.Review paper

Journal of Agronomy, Technology and Engineering Management, 1(1): 57-64.
The aim of this manuscript was to evaluate the drinking water resources of one of the most significant regions of Georgia-Kakheti and research the possibilities of their rational utilization taking into account the satisfaction of local population’s demand on drinking water. In this connection we researched such components of water resources as, outputs of artesian springs, underground water flow of river Alazani, water resources formed on Kakheti municipal territories and qualitative data of water resources per capita. The artesian wells of river Alazani’s subsoil waters are characterized, which are significant reserve of fresh water. It is underlined, that the outputs of the tributaries of river Alazani (especially the left ones) allow satisfying the population of Kakheti region with drinking water. The present condition of network of drinking water supply is also considered and the ways of their improvement. The recommendations are given for sustainable use of Alazani-Iori water resources according to the municipalities and possibilities of drinking water production satisfying international standards.Original research paper

Journal of Agronomy, Technology and Engineering Management, 1(1): 65-70.
Since the main components of essential oils are considered responsible for their biological activity, the chromatographic analysis of star anise essential oil was done. The identification of the essential oil compounds was carried out by matching their linear retention indices and MS spectra with those of authentic standards from MS library data bases. The main constituent was trans-anethole with 84.79% while 24 other constituents in total made less than 15.00% of the studied essential oil.Original research paper

Journal of Agronomy, Technology and Engineering Management, 1(1): 71-77.
The aim of our study was to determinate nutrient's content and organic matter degradability of different morphological parts (whole plants, stalks, leaves) of maize hybrids dent and dent x flint. Hybrids dent x flint - Mesnil, Chambord, Queen, and hybrids dent- Aude, Meridien, KX 1393, Omero were used. Concentration of crude protein (CP) in leaves was twice higher than in stalks (in average 117.0 g.kg-1 DM and 53.0 g.kg-1 DM, resp.). The differences in CP were also among hybrids in all plant parts. In sacco experiment was carried out on three rumen canullated cows. Hybrids dent x flint had in average higher effective organic matter degradability in whole plants (56.1 %), stalks (38.8 %) and leaves (49.2 %) than hybrids dent (53.8 %, 35.2 % and 43.3 %). Also, the rate of degradation of organic matter (OM) was higher for hybrids dent x flint than for dent. Organic matter in the stalks was degraded more slowly than in leaves.Original research paper

Journal of Agronomy, Technology and Engineering Management, 1(1): 78-83.
Alteration of the secondary metabolism is one the responses of plants to environmental changes. As part of this secondary metabolism, Brassicaceae is distinguished by the presence of numerous bioactive compounds with health-promoting properties such as glucosinolates, phenolics and anthocyanins. These bioactive compounds are enhanced after elicitors’ application in sprouts and young plants. The most effective pathway involved in such enhancement has been reported to be related to jasmonic acid (JA). JA and its volatile methyl ester methyl jasmonate (MeJa) act through transduction pathway resulting in a significant accumulation of glucosinolates and flavonoids. However, optimization of secondary metabolites production depended on crop, concentration of MeJa, number of applications, and developmental stage of the plant. As the effects of MeJa on phytochemicals on Bimi® (a new commercial broccoli coming from a hybrid between conventional broccoli and Chinese cabbage) and red cabbage, have not been studied in adult plants, in this work, we were focused on the effects on production of secondary metabolites and mineral concentrations in commercial plants. Also, the evaluation of the quality and stability of extracts was carried out. The increases of bioactive compounds obtained were promising for obtaining high quality extracts.Original research paper
NIKOLOVA, N. and KOCEVSKI, D. (2018) Quality of hen's egg shell in conditions of high temperatures.
Journal of Agronomy, Technology and Engineering Management, 1(1): 84-90.
In this paper was examined the influence of high temperatures on eggs which originated from a poultry farm situated at the south of Republic of Macedonia. In this region the average summer temperatures are always higher than the average summer temperatures in the rest of the country. The experiment lasted for 9 months and comprised a period of three seasons: summer, autumn and winter. Layers were two different ages: younger – up to 40-week of age, and older – over 40-week of age. All production parameters of the flocks were recorded: production of eggs, mortality, feed-consumption, body weight and the percentage of broken and cracked eggs during the research. 50 eggs monthly out of each age group were examined, or more exactly, 877 eggs of both age groups up to the end of the experiment. An analysis of egg mass, eggshell mass and percentage of calcium carbonate in the eggshell was performed. At the end of the research the results were statistically processed according to method of the Least Squares Means. High temperatures in the region had highly significant influence (p<0.01) over egg size, which was 2.16 g smaller than the average. The heat stress showed high significance (p<0.01) concerning the percentage of calcium carbonate into the egg shell, which in the summer months was the lowest and ran to 90.74%, in the autumn months it ran to 92.01%, and during the winter months it was the highest, 93.86%. The percentage of broken and cracked eggs per month was the highest in the summer period. It ran 1.92% to 3.29% in different ages of layers. The received results in this way proved the negative effect, caused by the heat stress on the quality of eggshell.Original research paper

Journal of Agronomy, Technology and Engineering Management, 1(1): 91-98.
Aim of the trial was to investigate the influence of Artemisia absinthium, Thymus vulgaris, Menthae piperitae and Thymus serpyllum mixtures in broilers nutrition on productive characteristics and biochemical blood status. Trial involved two treatments with the total of 80 broilers within four replicates. Control treatment (C) of chickens was fed with basic commercial diet mixture, while the experimental treatment (E) was fed with the same basic mixture only with addition of 2.0 g/100g medicinal plants mixture. Addition of Artemisia absinthium, Thymus vulgaris, Menthae piperitae and Thymus serpyllum has led to the higher body weight of chickens at the end of the sixth week of the trail (2087.3±230,22 g), followed by control treatment (2059.8±210.63 g) without statistically significant differences (p>0.05). Feed conversion ratio was uniform for the entire trial period, without significant differences. European broiler index was higher in E (226.4±4.21 %) with the lower mortality rate (2.6±0.7 %). In recorded amounts of triglycerides and total cholesterol significant differences was absent, while the low density lipoprotein (LDL) and non-high density lipoprotein (non HDL) in broilers on E treatment recorder statistically significant (p<0.05) differences compared to a control treatment. The highest amount of high density lipoprotein (HDL) with statistical significance (42.8±1.28 mg/dl) was determined in E treatment. Having in mind aforementioned and on the base on the gained results, it can be concluded that the addition of Artemisia absinthium, Thymus vulgaris, Menthae piperitae and Thymus serpyllum in broilers nutrition has positive influence on production characteristics and biochemical blood status of chickens.Original research paper
CANE, P. (2018) Do food recalls have a greater effect on consumers’ trust when they involve healthy, organic and protected designation of origin foods and, if yes, why?
Journal of Agronomy, Technology and Engineering Management, 1(1): 99-109.
Food safety concern has dramatically increased in the past decade. Concerns have arisen due to the fact that contaminated food products can result in serious risk to the wellbeing and health of consumers, including but not limited to outbreaks of Listeria monocytogenes, Escherichia coli (E. coli), and Salmonella. It is commonly accepted that product recalls have a negative impact on brand confidence, sales and pricing and, in some cases, the public’s perception of the food industry as a whole. Current consumer expectation towards food safety is on the increase and ranges from the assumption that food not only needs to be safe, but that nutrition shall also contribute actively to improve physical health condition and well-being. The aim of this paper is to investigate consumers’ reactions to food recalls which involve different kinds of products, through a comparison of highly processed foods versus foods that claim to be “healthier” in nature (eg. health foods, organic products and protected designation of origin). It will focus on the loss in confidence of brand loyalty and market distrust. The study combines case history analysis with insights drawn from 270 Italians, framing a profile of consumers’ expectation and reaction to food scandals. Research was conducted using an online questionnaire, in June 2018. It is evidenced that consumers are more tolerant when recalls involve heavily processed foods but tend to react more firmly when they involve foods and brands claiming to be “healthy” or organic products and protected designations of origins. Nowadays more than ever, consumer’s trust is as much a function of sharing company values and having brand affinity. Our conclusion is that foods that share specific set of values with consumers, such as ethics, quality and health, result in a higher degree of brand loyalty. This can easily be a double-edged sword which can result in a far stronger disapproval when the brand fails to keep their promise of health and quality.Original research paper

Journal of Agronomy, Technology and Engineering Management, 1(1): 110-118.
The aim this study was to evaluate the effect of 6-week application of zinc protein hydrolysate Bioplex-Zn to feed mixtures for rabbits and combinative application with 0.1% concentration thyme plant extract applied into water during the growing period on the selected parameters of meat quality and the caecal and faecal microbiota. Experiment was realized on 96 post-weaned rabbits (meat line M91 a P91). They were randomly divided into 4 similar experimental groups (EG), with 24 animals in each group. The rabbits in the group 1EG and 3EG were fed the same commercially available diet with no zinc additive. The feed mixture in the 2EG and 4EG was additionally administered with a dose of 33.3 g Bioplex-Zn per 100 kg (this is addition of 50 mg Zn/kg feed mixture). The rabbits in the group 3EG and 4EG received a dose with (0.1% Thymus vulgaris L. plant extract) applied into drinking water. Their beneficial effect was tested in a fattening experiment during 42 days. At the end of the experiment, 6 animals from each group were slaughtered. Meat quality was analysed from MLD (Musculus longissimus dorsi) samples. The amino acids and fatty acids contents were examined, showing statistically significant changes (P≤0.05). The caecal chymus were collected to detect the total bacterial content. The faecal samples were collected on day 1 and 42. To check microbiota, sampling of faecal mixtures per each group was performed at the start and end of the experiment. Samples were treated using the standard microbiological dilution method by plating appropriate dilutions on the selective media according to ISO. Microbiota was expressed in CFU.g-1. The treatment did not have a negative influence on the pH, colour, water-holding capacity, protein and fat contents or energetic value of the rabbit carcass.The beneficial effect of combination plant extract Thymus vulgaris and zinc additive administration was manifested by the anti-coccidian effect in rabbits.Original research paper

Journal of Agronomy, Technology and Engineering Management, 1(1): 119-123.
Common carp is worldwide domesticated freshwater fish species. Cage system of carp production represents a type of intensive production. Dressing percentage of carp is important from economical point of view. It is also an important parameter in all technological operations related to fish processing. The aim of this study was to determined yield of male and female common carp as the ratio of the fish weight and the carcass without the head, scales, fins and internal organs. The obtained results showed slightly higher body height and head length values in the females compared to the males. Weight parameters obtained had no statistically significant difference. Total length, standard length and carcass length of females compared to males had a statistically significant difference. In female carp, significantly higher carcass weight and viscera weight were found. Significant differences were found in head weight and gonad weight as well in gonadosomatic index value in the favour of male carps.Original research paper

Journal of Agronomy, Technology and Engineering Management, 1(1): 124-129.
Fish are accurate and suitable bioindicators and biomonitors for marine water pollution analyses. Depending on the diet type, the harmful and dangerous substances are accumulated in their bodies in the larger quantities than in the water column, which directly affects human health. Lead is a toxic metal whose widespread use has caused extensive environmental contamination and health problems in many parts of the world, especially in developing countries. The aim of this research was to obtain the data on lead contamination in fish and seawater samples from coastal region of Bar harbour. The highest lead concentrations have been found in muscles of T. mediterraneus and M. cephalus. The lead concentrations in water samples have varied depending on season and locality.

The editors of this journal enforce a rigorous peer-review process together with strict ethical policies and standards to ensure to add high quality scientific works to the field of scholarly publication. Unfortunately, cases of plagiarism, data falsification, image manipulation, inappropriate authorship credit, and the like, do arise. The editors of Journal of Agronomy, Technology and Engineering Management take such publishing ethics issues very seriously and are trained to proceed in such cases with a zero tolerance policy.
Authors wishing to publish their papers in Journal of Agronomy, Technology and Engineering Management must abide to the following:
- Any facts that might be perceived as a possible conflict of interest of the author(s) must be disclosed in the paper prior to submission.
- Authors should accurately present their research findings and include an objective discussion of the significance of their findings.
- Data and methods used in the research need to be presented in sufficient detail in the paper, so that other researchers can replicate the work.
- Simultaneous submission of manuscripts to more than one journal is not tolerated.
- Republishing content that is not novel is not tolerated (for example, an English translation of a paper that is already published in another language will not be accepted).
- If errors and inaccuracies are found by the authors after publication of their paper, they need to be promptly communicated to the editors of this journal so that appropriate actions can be taken.
- Your manuscript should not contain any information that has already been published. If you include already published figures or images, please obtain the necessary permission from the copyright holder to publish under the CC-BY license.
- Plagiarism, data fabrication and image manipulation are not tolerated.
During the submission process, please suggest three potential reviewers with the appropriate expertise to review the manuscript. The editors will not necessarily approach these referees. Please provide detailed contact information (address, e-mail address). The proposed referees should neither be current collaborators of the co-authors nor have published with any of the co-authors of the manuscript within the last five years. Proposed reviewers should be from different institutions to the authors. You may identify appropriate Editorial Board members of the journal as potential reviewers. You may suggest reviewers from among the authors that you frequently cite in your paper.
EDITORIAL PROCEDURES AND PEER-REVIEW
All submitted manuscripts received by the Editorial Office will be checked by a professional in-house Managing Editor to determine whether they are properly prepared and whether they follow the ethical policies of the journal. Manuscripts that do not fit the journal's ethics policy or do not meet the standards of the journal will be rejected before peer-review. Manuscripts that are not properly prepared will be returned to the authors for revision and resubmission. After these checks, the Managing Editor will consult the journals’ Editor-in-Chief or Associate Editors to determine whether the manuscript fits the scope of the journal and whether it is scientifically sound. No judgment on the potential impact of the work will be made at this stage. Reject decisions at this stage will be verified by the Editor-in-Chief.
Once a manuscript passes the initial checks, it will be assigned to at least two independent experts for peer-review. A double-blind peer-review process is applied, where authors' identities are not known to reviewers.
In the case of regular submissions, in-house assistant editors will invite experts, including recommendations by an academic editor. These experts may also include Editorial Board members and Guest Editors of the journal. Potential reviewers suggested by the authors may also be considered. Reviewers should not have published with any of the co-authors during the past five years and should not currently work or collaborate with any of the institutions of the co-authors of the submitted manuscript.
Editorial Decision and Revision
All the articles, reviews and communications published in Journal of Agronomy, Technology and Engineering Management go through the peer-review process and receive at least two reviews . The in-house editor will communicate the decision of the academic editor, which will be one of the following:
- Accept after Minor Revisions: The paper is in principle accepted after revision based on the reviewer’s comments. Authors are given five days for minor revisions.
- Reconsider after Major Revisions: The acceptance of the manuscript would depend on the revisions. The author needs to provide a point by point response or provide a rebuttal if some of the reviewer’s comments cannot be revised. Usually, only one round of major revisions is allowed. However, if the authors provide sound reasoned response that in the eyes of the editor/s or reviewers merits another round, it will be allowed. Similarly, new authors and authors where English is a second language are granted leeway here, as the journal’s primary objective is to promote quality technology and we will strive to reduce barriers such as language and/or inexperience, as long as the underlying science and technology is of quality, relevance and clearly visible in the manuscript. In each case, authors will be asked to resubmit the revised paper within a suitable time frame, and the revised version will be returned to the reviewer/s for further comments. In the case of a Major Revision ruling where the reviewer is mentoring a new scientist (which should be noted in the first submission packet) and provides guidance by suggesting that the scope of original manuscript is not original enough for publication and provides suggestions redirecting the scope of the article; as long as the author’s follow these directions, or similar action, the paper will continue as normal. However, should the authors ignore this redirection advice, the article will most likely be rejected on the next round.
- Suspended and Encourage Resubmission: If additional experiments are needed to support the conclusions, or more time is needed than is possible under normal Major revision pathway, the manuscript will be suspended, and the authors will be encouraged to re-submit the paper once further experiments have been conducted and or re-direction course followed. Upon re-submission the submission date will be reset, and the paper will be treated as a new submission.
- Reject: The article has serious flaws, and/or makes no original significant contribution. No offer of resubmission to the journal is provided. If the authors later re-submit this, after making major revisions, the authors must alert the editors that this article was previously rejected.
All reviewer comments should be responded to in a point-by-point fashion. Where the authors disagree with a reviewer, they must provide a clear response. New scientists and engineers should take notice that in the case where there are numerous reviewer concerns; the reviewer may very well stop reviewing the article and simply make a decision and thereby the authors should not assume that what the reviewer pointed out is the only thing wrong with the manuscript. It is not the reviewer’s job to write the article for the authors; hence the authors should strive to go back through the manuscript and keep in mind the reviewer’s concerns and see where else in the manuscript that this advice could and should be applied and be diligent in making all necessary corrections and modifications. If you need help, please ask, we will do our best to mentor new scientists and put them on a path to success.
Production and Publication
Once accepted, the manuscript will undergo professional copy-editing, English editing, proofreading by the authors, final corrections, pagination, and, publication on the http://www.fimek.edu.rs/jatem.html website.
