The bush is semi-erect, featuring lanceolate to inversely egg-shaped leaves in dark green color and cylindrical inflorescences 2-4 cm long with blue and purple corollas. The variety's seeds have a bean-like and kidney-like shape, a yellow-brown color, and a weight of about 2 g per 1000 seeds. Diana is primarily grown as an annual crop and exhibits medium bushiness and foliage coverage of 48-50%. This variety is characterized by mid-maturity and high productivity in terms of seed yield, reaching up to 5.6 c/ha, and forage mass, with dry matter yields ranging from 96 to 188 c/ha under 3-4 cuts on irrigated land. Diana possesses tolerance to major diseases, including alfalfa stunt, ensuring its competitiveness in growing regions. Additionally, the variety regrows well in spring and after cuts, facilitating the stable production of high-quality forage. Alfalfa Diana is a valuable forage crop due to its high protein content and is also used as a green manure, enriching the soil with nitrogen and improving its structure through loosening and humus accumulation. The variety contributes to weed suppression and ensures an economic effect both at the seed production stage and in the production of nutritious feed for livestock.
