Abstract

Organic agriculture as a system of sustainable agricultural production today is essential part in the development of value chains of products that have high nutritional value and environmental characteristics. Soybean is an important source of protein and oil, both for food and feed and belongs to one of the most important field crops. Continuous work on improving cultivation technology in organic systems of agricultural production is of great importance for expanding sustainable farming systems. Limited mineral nutrition in organic production has resulted in a large number of studies that were aimed primarily at increasing yields, as well as the quality of the final product, where the application of foliar fertilizers and fertilizers generally occupies an important place. The research aimed to present the possibility and importance of the application of fertilizers in organic soybean production. Three preparations (Italpollina NPK 4:4:4, Biofor soja, Wuxal ascofol) on soybean variety NS Kaća were tested. The analysis of the obtained results showed that the weight of 1000 grains differed statistically significantly between treatments, while fertilization reacted positively to the soybean grain yield in relation to the control variant, but no statistical significance was determined. The highest yield was determined on the treatment with Biofor soja (4.3 t ha-1 ).The results obtained after one year of research can serve as a guideline for improving the technology of soybean cultivation in organic production, but it is necessary to conduct further research on the application of different foliar fertilizers at different stages of growth, as well as in different doses.
