The development of effective methods that ensure the biologization of soybean cultivation is of theoretical and practical importance in the formation of completely stable and most productive agroecosystems. This paper reflects the results of field studies to identify the impact of the use of foliar multifunctional biocomplexes on the morphometric, economic characteristics of plants, the formation of seed productivity of the soybean variety Kitrossa in the conditions of the Amur region. The effectiveness of the use of a multifunctional fertilizer complex on soybean, which enhances the production processes of plants and optimizes their nutrition, as well as a biophytoncide complex that activates photosynthesis and the accumulation of dry matter, has been determined. The role of seed inoculation with a highly active strain of soybean rhizobia is considered. The results of studying the foliar use of biocomplexes considered on soybeans in various compositions, including the use on seeds and plants, as well as jointly; with pre-sowing inoculation of seeds and without it; on unfertilized and fertilized backgrounds. Agricultural practices, including inoculation of seeds with the applied strain, pre-sowing treatment of seeds and sowing with Spartan + Nutri-Fight RK fertilizer complex and Belyi Zhemchug Soya biophytoncide complex in recommended dosages and regulations, ensure the formation of a soybean yield of up to 3 t/ha.
