Soybean variety Rogiznyanka is characterized by high cold resistance and resistance to diseases and pests, ensuring reliable cultivation under various climatic conditions. The plant has medium or high height, from 85 to 95 cm, with lanceolate-shaped lateral leaflets and large leaves. Growth type varies from semi-determinate to indeterminate, with inflorescences being racemose clusters with purple flowers. The height of attachment of lower pods is 14.5–15.3 cm, facilitating harvesting. The variety is early-maturing, with a maturity period of about 105 days, and is intended for grain use. Seeds are oval, yellow with a black hilum, weighing 160–180 g per 1000 seeds. A key feature is high protein content (39–41%) and oil content (19–21%), making this variety attractive for producing food and feed products. Potential yield of the variety reaches 4–4.5 tons per hectare under optimal growing conditions. To achieve maximum plant uniformity and maintain plant density per unit area, it is recommended to treat seeds with biopreparations based on Bradyrhizobium japonicum and Glomus intraradices, as well as to conduct two foliar applications of Fulvogumin. The variety demonstrates high drought and seed shattering resistance, further enhancing its adaptability and yield stability under adverse weather conditions.
