Against the background of N30P30K30 application, seed treatment with a biological product based on Brady-rhizobium japonicum, and the use of a plant growth regulator, the longest growing season was observed in the Koroleva soybean variety and lasted 132 days. The highest grain yield (3.07-3.28 t/ha) was achieved by growing soybean varieties of different maturity groups, such as Rogiznyanka, Palada, Titan, and Koroleva. The length of the growing season for these varieties against the background of nutrition optimization (application of N30P30K30 to the soil, seed treatment with Bradyrhizobium japonicum + plant growth regulator) was 124-134 days. The highest yield in the seed inoculation variant was observed in the Rogiznyanka, Pallada, and Evridika soybean varieties, increasing by 0.14, 0.15, and 0.25 t/ha, respectively. A smaller increase in soybean grain yield was achieved by using a plant growth regulator. The grain yield of these soybean varieties (3.07-3.28 t/ha) ensures high production profitability.
