Soybean variety Tavria is a mid-season hybrid with high yield potential and oil content of about 22%. Plants are characterized by indeterminate growth type, moderate stem lodging, and semi-erect bush form. The height of the first pod attachment is 13-15 cm, which facilitates harvesting. This variety adapts well to various soil-climate conditions, making it suitable for cultivation in different regions. Moreover, Tavria exhibits high resistance to major diseases and stress factors, ensuring stable and reliable yields. To increase yield and improve atmospheric nitrogen fixation, it is recommended to use the bio-preparation Grafex, containing Bradyrhizobium japonicum bacteria. This preparation is intended for seed treatment of soybeans and promotes increased crop productivity. The application rate is 50 g per hectare at a seed sowing rate of 80-100 kg. Grafex can be applied directly in seed drills and combined with commonly used seed treatments, simplifying the technological process and enhancing treatment efficiency. The preparation is compatible with talc- and graphite-based inoculants, expanding its application possibilities. Thus, soybean variety Tavria in combination with the use of bio-preparation Grafex ensures high yield, resistance to adverse conditions, and effective use of atmospheric nitrogen. This makes the variety an attractive choice for farmers seeking high-quality and stable soybean yields.
