Abstract
The article presents the results of scientific research on the growth-stimulating preparations in the pre-sowing treatment of soybean seeds and crops according to the development phases in the foreststeppe zone of the Middle Volga. It contains the results of the 2016-2018 research with an assessment of indicators of plant safety, photosynthetic activity and soybean yield in different treatment options by growth factors. The two-component preparations in pre-sowing seed treatment contribute to better soybean germination up to 78.12%. The pre-sowing treatment of seeds with Risotorphine and Raykat Start preparations forms the maximum leaf area. Comparing three years, we can say that the leaves work more productively in the variants with the use of Risotorphine and Raykat Start in pre-sowing treatment. Weather conditions in 2018 allowed soybean crops to form a high yield. The yield level was in the range of 1.48 - 1.98 t / ha. Inoculation of seeds with Raykat Start followed by crops treatment in the phase of 3-5 leaves and budding allowed achieving maximum yield for all years of research. After treating the seeds with Raykat Start, the maximum grain yield was 1.40 t/ha with a double-treatment of crops by microfertilizing mixture Megamix Profi in a phase of 3-5 leaves and budding.

2 Materials and methodsThe lack of complete protein in the diet of modern man is a major nutritional problem
The objective of the research is to assess the parameters of plant safety, photosynthetic activity of plants in crops, soybean yield in crops, depending on the use of growth-stimulating preparations in seed treatment and during vegetation
Our studies revealed that soybean crops had the formation of a high level of photosynthetic potential, and showed a low rate of accumulation of dry organic matter with an indicator of the net productivity of photosynthesis
Summary
The lack of complete protein in the diet of modern man is a major nutritional problem. Each living organism consists of proteins that are involved in the most important chemical processes supporting the body's vital functions. The need to further increase the production of vegetable protein lies with an increase in the population of the globe and its direct use in human nutrition [1–4]. The protein problem is very relevant to agricultural production. Its seeds are rich in proteins up to 41%, in fats up to 21%, and have an almost perfect amino acid composition protein, polyunsaturated fatty acids (ω-3 and ω-6), much water- and fat-soluble vitamins, especially vitamin E, the most important natural antioxidant, minerals and other components that have the beneficial biological effect for the human body
