Russian. The article presents the results of research aimed at improving the technology of cultivation of grain legume crops – peas and soybeans in the forest-steppe zone of the Middle Volga region. The research showed that to increase leaf surface area, photosynthetic potential (PP) and net photosynthetic productivity (NSPP) of the studied crops, the tillage technology according to the scheme is more effective: discing at 10-12 cm + plowing at 25-27 cm and plant protection with seed dressing Delit Pro, KS (pyraclostrobin, 200 g/l) 0.5 l/t together with biopreparation BiosolbiSan, J (Bacillus subtilis, strain Ch-13) 1 l/t; treatment with Pivot herbicide, VPK (imazetapyr, 100 g/l) 0.5 l/ha + Biofungicide BisolbiSan, J (Bacillus subtilis, strain Ch-13) 1 l/ha.
