Assessment of soybean productivity factors under conditions of the southern part of the non-black earth zone of Russia

Abstract

Abstract In modern conditions, the demand for soybeans is increasing both in the world and in the Russian Federation. Analysis of the trends characterizing the production of this crop has showed the prevalence of extensive factors - the growth of sown areas in all federal districts. Soybean yield is also growing, but its absolute size is significantly lower than the world average. In addition, the productivity of soybeans significantly depends on the hydrometeorological conditions of cultivation. Since most of the territory of the Russian Federation belongs to the zone of risky farming, plant support means are required. The article provides an overview of the influence of growth stimulants X-Site, G and Stimulate, G on soybean yield in Ryazan region. The results have showed that in order to obtain high and stable yields of this agricultural crop, it is necessary to feed soybeans in budding and flowering phases with plant growth regulator Stimulate, F with a consumption rate of 0.5 l/ha. This will increase the yield of the crop by 2.5 dt/ha and increase the protein content to 40.8 %.
