Abstract

Soybean is the most important agricultural crop, necessary to meet the needs of the population and livestock industries with highly digestible vegetable protein. The article contains a retrospective analysis of soybean cultivation in the Russian Federation and Ryazan region. The factors of the growing popularity of this agricultural crop were determined and included high marginality, significant content of highly digestible protein, amino acids and minerals, resistance to diseases and pests. The factors that had the greatest impact on the yield and quality of soybeans were identified - these were natural and climatic conditions, soil fertility, applied agricultural methods of cultivation, and the choice of variety. The conducted 5-year retrospective analysis showed that more than 50% of agricultural enterprises in Ryazan region incorrectly selected a variety for cultivation. As a result, the actual yield was lower than the potential. In this regard, the article provides recommendations for adjusting the economic activities of agricultural enterprises.
