Efficiency of symbiotic activity of crops of soya bean in conditions of Polisya of Ukraine

Abstract

Goal. Determine the effect of seed inoculation and foliar nutrition on soil nutrient nitrogen and soybean yield. Methods. Agrochemical (for determining the chemical composition of soil, plants), mathematical (in particular, dispersive), biometric (for determining the formation and activity of the symbiotic apparatus and their relationship with the photosynthetic activity of the crops). Results The results of many years of research on the influence of the elements of the technology of cultivation on providing the soil with biological nitrogen and the yield of soybeans in the zone of sufficient moisture of the Polissya region of Ukraine are presented. The formation of tubers is shown depending on seed inoculation and foliar feeding. The amount of biological nitrogen and the equivalent of ammonium nitrate are calculated. Conclusions In the conditions of the Polissya of Ukraine it is necessary to conduct research to study the complex of technological elements (varieties, methods of sowing, seed rate, etc.).
