Research conducted in 2016-2018 in the field rotation of the Laboratory of Agricultural Technologies and Plant Protection. In the field experiment soybean varieties Mezenka and Osmon were studied, backgrounds: non-fertilized and fertilized (estimated dose of mineral fertilizers for the planned yield of 3 t/ha (N63-150P75-150K149-164), seed treatment with growth stimulant Alfastim, crop treatment during the growing season with organic-mineral fertilizer Polidon BIO. The repetition of the experiment is fourfold. Plot area – 10 m2. Sowing was carried out with a SKS-6-10 seeder in a wide-row method (45 cm inter-row spacing) in the second decade of May (May 13-14). It was established that both varieties (Mezenka, Osmon) are technological, the height of attachment of the lower bean is above 16 cm, i.e. suitable for cleaning by direct combining with minimal losses. The most promising for cultivation in the north of the Central Black Earth Region is the Osmon soybean variety, which has a shorter growing season and effectively uses natural soil fertility and forms grain yield of 2,7 t/ha on soils with an average fertility level without the use of mineral fertilizers. On this variety, it is more expedient to use Alfastim growth stimulator at a dose of 50 ml per 1 ton of seeds and Polidon BIO microfertilizer in the budding phase at a dose of 1 l/ha to stabilize high productivity. The use of these preparations is economically justified: at low cost, a high level of profitability remains – 223-234%.
