Relevance. The task of modern feed production is to increase feed production, as well as improve their quality and energy saturation. A special place in solving this problem belongs to perennial legumes and grasses. At the same time, it is important to use precisely those crops and varieties that have the greatest biological potential.Methods. The objects of research were meadow clover (Pochinkovets variety and Topaz variety), timofeevka meadow (VIC 911 variety), ryegrass pasture (Karat variety and Express variety), for the realization of the biological potential of which solid mineral fertilizers (ammonium nitrate, double superphosphate, potassium chloride) are needed, as well as concentrated liquid complex fertilizers of the series “Ultramagus.”Results. Among the studied species of perennial grasses, meadow clover has the highest yield, so among the clover varieties, the Pochinkovets variety had the greatest potential. Varieties of meadow clover increased the collection of dry matter when applying solid phosphorus-potassium fertilizers and liquid complex fertilizer “Ultramag Combi”. The highest yield was obtained in variants with the combined use of root fertilization with solid fertilizers at the rate of P80K120 and foliar fertilization with liquid complex fertilizer “Ultramag Combi”. The yield of meadow clover, depending on the variety, ranged from 12.05 to 12.46 t/ha. Varieties of meadow clover Pochinkovets and Topaz in the conditions of the Smolensk region form a tall monodominant herbage capable of intensive regrowth during the season and yielding at least two full-fledged mowing under optimal cultivation conditions.
