Increasing the production of soybeans requires an increase in the area planted with soybeans. The disruption of traditional crop rotations and the increase in the share of marginal crops that meet the demands of the market necessitates the search for optimal predecessors with minimal disruption of agricultural science. The purpose of this study was to evaluate the performance of soybean varieties of different geographical origin when grown after different predecessors. The research was conducted in 2022-2024 on typical black soil in the weather conditions of the Kursk region. The object of the study was domestic – Leader 1, SK Farta, Belgorodskaya 7, Shatilovskaya 17 and foreign (Canada) – Hana soybean varieties recommended for the light zone of the Central Chernozem region. The experiment used traditional cultivation technology with N₃₀P₄₀K₃₀ application, seeding rate of 650 thousand seeds/ha, and treatment in the phase of the 1st trifoliate leaf with a tank mixture of herbicides with fertilization. The assessment of plant growth processes in the agrocenosis and soybean productivity according to different predecessors was carried out according to the generally accepted methods in agronomy. The best results were obtained with the white lupine as a preceding crop, where the biological yield was 0.23 t/ha higher than with winter wheat as a preceding crop, and 0.38 t/ha higher than with winter rapeseed. In this case, the protein yield of soybeans reached 1.02 t/ha, with the best results achieved by the Hana variety. The energy assessment of soybean varieties based on a number of predecessors revealed the advantages of white lupine, which provided an increase in biological energy for protein and fat by 0.55-1.40 Gcal, or 6.1-16.2%.
