Organic production has a significant impact on human health, animal, food security and environmental sustainability. Pesticide exposures from conventional production may lead to important diseases, such as Parkinson’s disease, diabetes, brains damage, especially in children and certain types of cancer. Epidemiological studies highlight adverse effects of certain pesticides on children’s cognitive development. Use of pesticides in organic agriculture is restricted. Organic food are abundant with vitamins, antioxidants (vitamin C, polyphenols and flavonoids), minerals and dry matter content. Regular consumption of organic products (fruits and vegetables, dairy products and meat) significant reduces the risk of overweight, of preeclampsia in pregnancy and allergic disease. Organic meats and dairy products have a higher content of omega-3 fatty acids compared to conventional products and do not contain antibiotics. Due to the reduced amount of pesticide residues and an increased secondary plant metabolites, intake which are found in organic food, there is a reduction in health problems and a positive effect on health.

Thanks to the grain's high energy and nutritional value, oats are of great economic importance. The paper analyzed the productivity of oats on fertile soil, chernozem in a two-year period and in two variants of feeding: control (variants without feeding) and in the variant with digestate. Oat productivity parameters were analyzed: number of ears per panicle, grain mass per panicle and compared with grain yield per hectare. The results showed that year and digestate had a statistically significant effect on the number of spikelets per panicle of oats and that higher values of grain weight per panicle were achieved in the digestate variant compared to the control variant. The digestate had a significant effect on the increase in oat productivity parameters and its application in the oat crop is justified.

Tradition and gastronomy are synonyms that point us to lasting values and quality. People travel from faraway places to enjoy authentic food, characteristic of a certain area. In this way, many dishes are kept from being forgotten, and enjoying them is a form of sustainable tourism. The paper started from the hypothesis that gastronomic tourism has the potential to be the carrier of the economic development of rural areas. Tourists want an authentic experience through food. In this way, tradition is preserved from oblivion, and rural areas revive and develop. There were questioned 218 tourists, visitors to 10 farms in Vojvodina as authentic objects of rural areas. The conclusion was reached that the rich gastronomy is a factor in attracting tourists that has a strong contractive effect, whether it is a primary, independent tourist motive or a complementary tourist offer.

Panicum miliaceum - millet is a gluten-free cereals with high nutritional value, rich in proteins, carbohydrates, phytic, phenolic and salicylic acids, minerals and vitamins: phosphorus, magnesium, iron, calcium, potassium, zinc and B complex vitamins. Millet flour is added to wheat flour to make bread and pastries and the aim is to obtain products with improved nutritional value. Before use, millet should be soaked in water for 6-12 hours, and only then thermally processed (cooked). Heat treatment affects the reduction of phytic acid content. Due to the high content of salicylic acid, millet is used in cosmetics, and it also has antifungal and anticancer properties. The grain is rich in magnesium and iron, which is why it is used by people suffering from anemia and cardiovascular diseases. The aim of this study is to indicate the importance of millet, production technology, yielding potential, nutritional value of the Biserka variety and impact on health.

The importance of sugar beet is great because it gives root yield of about 50 t ha-1 and 30 - 40 t of fresh leaves and heads of beet that is used for feeding cattle. In the Republic of Serbia are favorable agro-ecological and soil conditions for the production of sugar beet. In the structure of total arable land of the Republic of Serbia, sugar beet accounts for about 2% where 94% of it is in Vojvodina, which has the most favorable climate and soil conditions, tradition and proximity of capacities for root production and processing. In addition to its adaptability to climatic conditions, sugar beet reacting quickly to changes in meteorological factors which greatly affect root yield and sugar content. In the three-year trials it was examined morphological characteristics and the amount of a-amino N in five genotype of sugar beet. According to the survey results, the largest number of leaves at the genotypes at technological maturity had the genotype Otis (35.33) while the smallest had had genotype Severina (15:53). Genotype Otis, as a whole, had the highest leaf area (X=10193.13 and Xmax = 11483.79), and the lowest had genotype Severina (X = 4242.33; Xmin = 3982.44). The lowest average value of the amount of α -amino N indicators were found for Chiara and Laetitia (X = 2.23). The observed traits were largely depended on the genotypes and years. Genetic variation is necessary for successful breeding.

Sweet sorghum being a C4 crop accumulates more sugar in its stalks, also suitable for biofuel production and has high degree of tolerance to biotic and abiotic stresses. Morphological characteristics i.e., plant height, plant biomass, leaves on the stem, panicle length and yield of crude biomass of sweet sorghum genotypes were studied across different environments. Environments and genotype by environment interaction (GEI) had a significant effect on the yield of crude biomass. The smallest yield of crude biomass was achieved in 2016 (42.54 t ha(-1)), which was found significantly lower as compared to that in 2014 and 2015. The average plant height had a significant and positive correlation with the number of leaves (0.54) and number of leaves had highly a significant and positive correlation with the mass of stem (0.46) and panicle length (0.61). Biomass yield was positively and significantly correlated with precipitation (0.72) and negatively significantly correlated with temperature (-0.57). In breeding of sweet sorghum, the highest attention should be given to biomass yield as it manage the whole variation and controlled by polygenes.

Soybean [Glycine max (L.) Merr.] is the most important legume because it is an essential source of dietary protein and oil for animal feed and food production. Good soil with wellplanned program of fertilization is the main factor of soybean production. Soybean yield will be reduced when essential nutrients are deficient. Sufficient soil fertility combined with a well-planned fertilization program is a main component for high soybean production. The aim of this investigation was to estimate the effects of fertilization and seed inoculation on height of soybean plant in humid year. Two factors were tested: 1. CAN fertilization and 2. seed inoculation. Four treatments of CAN fertilization were tested: Control - 0 kg N ha-1; 50 kg N ha-1; 100 kg N ha-1 and 150 kg N ha-1. Two factors of seed inoculation (SI) were tested: Without SI and with SI. Results showed that fertilizers and seed inoculation significantly increased the values of soybean productivity. Cost effective is the application of 50 kg N ha-1 and it is recommended on the basis of this study.

Trail with sugar beet was set up during three years. Yield parameters were analyzed on five different origins of sugar beet varieties. Variety had a statistically significant affect on the yield sugar beet. The average yield for all tested varieties was 54.25 t ha-1. The highest average yield was achieved by varieties Chiara, 72.58 t ha-1, and Otis, 64.55 t ha-1 the variety Severina the lowest, 36.76 t ha-1. The variety Severina had the highest average crystal sugar content, 16.65%. Crystalline sugar yield, as the most important indicator of sugar beet yield, statistically significantly depended on the variety. Quality, namely technological root value largely depends of variety. Coarseness of the root was in inverse proportion to the content of sugar., Ogledi sa šećernom repom izvođeni su tokom tri godine. Analizirani su parametri rodnosti pet sorti šećerne repe različitog porekla. Sorta je imala statistički značajan uticaj na prinosa korena šećerne repe. Prosečan prinos korena za sve testirane sorte iznosio je 54,25 t ha-1. Najviši prinos imale su sorte Chiara, 72,58 tha-1 i Otis, 64,55 t ha- 1, a sorta Severina najniži, 36,76 tha-1. Sorta Severina imala je najveći sadržaj kristalnog šećera, 16,65%. Prinos kristalnog šećera, kao najvažniji pokazatelj rodnosti šećerne repe, statistički je značajno zavisio od sorte. Tehnološka vrednost korena u velikoj meri zavisila je od sorte. Krupnoća korena bila je u obrnutoj proporciji sa sadržajem kristalnog šećera.

Veliki privredni značaj šećerne repe (Beta vulgaris ssp. esculenta var. saccharifera L.) ogleda se načinu korišćenja glavnog i sporednih proizvoda, kako žetvenih ostataka, tako i ostataka koji ostaju posle izdvajanja kristalnog šećera saharoze. Svi dobijeni proizvodi imaju veliku upotrebnu vrednost tako da gajenjem ove ratarske biljke i proizvođači i prerađivači ostvaruju veliku ekonomsku korist. Cilj ovog istraživanja bio je da se utvrdi uticaj različitih količina i odnosa NPK asimilativa na povećanje produktivnih i kvalitativnih osobina šećerne repe. Predmet istraživanja bilo je pet genotipova šećerne repe koje se međusobno razlikuju po proizvodnim osobinama. To su sorte Otis (N tip), Chiara (NE tip), Laetitia (N tip), Irina (NE tip) i Severina (ZN tip). Trogodišnji poljski ogledi postavljeni su na zemljištu homogenih agrohemijskih i fizičkih osobina po principu slučajnog blok sistema sa četiri ponavljanja uz primenu savremenih agrotehničkih mera koje se primenjuju u komercijalnoj proizvodnji na području južnog Banata. Proučavane su sledeće morfološke, proizvodne i kvalitativne osobine korena: broj listova i lisna površina po biljci, masa korena, prinos korena i prinos kristalnog šećera, digestija, sadržaj nešećernih materija u korenu (α-amino azot, K i Na), kao i odnos ukupnog i kristalnog šećera (iskorišćeni šećer). Sorta Otis je obrazovala najviše listova i lisnu površinu i dala najveći prinos korena, ali je imala najmanju prosečnu digestiju. Visok prosečan prinos korena ostvaren je sortom Chiara, ali i najveći sadržaj α-amino azota i kalijuma u soku. Sorta Laetitia je dala najveći prinos šećera, iako je najmanji procenat iskorišćenog šećera. Obrnute vrednosti dobijene su sortom Irina (najmanji prinos šećera, ali najpovoljniji odnos kristalnog i ukupnog šećera). Sorta Severina pripada šećernatijem tipu što su potvrdila i ova istraživanja tako da je, u trogodišnjem proseku imala najveću digestiju, ali i najmanji korena..., Great economy importance of sugar beet (Beta vulgaris ssp. esculenta var. saccharifera L.) reflects in a way of using main and side products like crop residues and other residues that remains after separation of crystal sugar – saccharose. All obtained products have huge value of use so, by planting this plant, both producers and processors generate significant economic gains. Aim of this research was to determinate influence of different amount and ratio of NPK nutrients on increase of productive and qualitative properties of sugar beet. The subjects of research were five sugar beet genotypes that differentiate each other by their productive properties. These sorts are: Otis (N type), Chiara (NE type), Laetitia (N type), Irina (NE type) and Severina (ZN type). Three years lasted field experiments by method of random block system in four repeated series, were set on homogeneous agrochemical and physical property land with the use of modern agro-technical interventions which were applied in commercially production in South Banat area. Following properties of sugar beet have been explored: number of leaves, leaf area per plant, mass of root, yield, crystal sugar yield, digestion, root non sugar substance contents (α-amino N, K, Na) as well as relation between total and crystal sugar (exploit sugar). Sort Otis formed the highest number of leaves and largest leaves area and biggest root yield but it has had minor digestion average. High root yield average was achieved by sort Chiara but also the highest percentage of α-amino N and K in its sugar beet root. Sort Laetitia had highest sugar yield, but also smallest percentage of exploit sugar. Inverted values has had sort Irina (smallest sugar yield but the best relation between crystal and total sugar...

The paper presents the variability of productive traits of six soybean varieties grown in conditions of increased nitrogen nutrition in the period 2006-2008. The trials were conducted in South Banat on the chernozem soil type. Soybean was grown under rain-fed conditions. Morphological traits were analyzed prior to harvest, while the grain yield was measured after harvest. The results show significant variations in the tested traits among the examined genotypes. The highest average yield had variety Sava, while in dry 2006, the higher yields achieved early varieties Proteinka and Valjevka. Increased nitrogen nutrition did not significantly affect the yield, especially in years with favorable rainfall schedule. Differences in production traits varied strongly among experimental years., U radu je proučavana varijabilnost produktivnih osobina šest sorti soje gajenih u uslovima pojačane ishrane biljaka azotom u periodu od 2006. do 2008. godine. Ogledi su postavljeni u južnom Banatu na zemljištu tipa černozem. Soja je gajena u uslovima prirodnog vodnog režima. Analize morfoloških osobina urađene su pre berbe soje, prinos zrna je određen posle berbe oglednih parcela. Rezultati su pokazali da između genotipova postoje značajna variranja u ispitivanim osobinama. Najveći prosečni prinos imala je sorta Sava, dok su u sušnoj 2006. godini, veće prinose ostvarile rane sorte Proteinka i Valjevka. Pojačana ishrana azotom nije značajno uticala na prinos, posebno u godinama sa povoljnijim rasporedom padavina. Razlike u proizvodnim osobinama su jako varirale po godinama istraživanja.
