The study was aimed to evaluate the influence of the growth regulators on the architectonics of the crops, nitrogen-fixing capacity, productivity, structure, and quality of the yield of soya and sorghum cultures in the conditions of grey forest soils of South-West of the Central Region of Russia (Bryansk region). Materials and Methods: field, laboratory, and statistical. The best effect was observed in variants that included Albit, Gibbersib, and Humistim for seed dressing and spraying of sugar sorghum and Sudan grass. Biopreparation Phitostim had a significant influence on the structure of crops and the productivity of soya.
