Promising direction for the development of agricultural production is growing alfalfa sowing. The crop is a valuable sideratum, a good nitrogen fertilizer that makes it possible to make a profit. Soil after growing legumes has improved properties due to replenishment nitrogen. Lucerne is a multivitamin plant. In the aboveground the vegetative mass of alfalfa contains ascorbic acid, carotene, saponins, alkaloids and ash substances. The rational use of mineral and organic fertilizers is of great importance in improving the productivity of perennial legumes. An analysis of literary sources shows that alfalfa sowing is a very valuable fodder crop in Ukraine. It is the cheapest feed rich in amino acid, protein and carotene. It has been found that the use of seed treatment and foliar feeding on alfalfa sowing crops improves the growth and development conditions of the crop and increases individual productivity. The results of three-year studies on the influence of pre-sowing treatment of seeds and foliar fertilizers on the formation of individual productivity of alfalfa sowing are presented. The research results are complex multidisciplinary in combining the fertilizer system with plant growth regulators in view of current trends in climate change. The development of effective regulations for the use of organic fertilizers for vegetation according to the classical types in the system of technology of cultivation of alfalfa sowing Sinyukh has been investigated. The treatment of alfalfa growth regulators with trace elements during the cultivation of alfalfa sowing promotes the formation of a large number of flowers, increasing the mass of seeds. It was found that the highest plant density, the number of productive stems per plant, the number of ripe beans in one inflorescence, the number of seeds in one bean on the variants of the experiment, where the treatment of seeds with bioregulator of growth of Saprogum and foliar fertilization of Vuksal fertilizer in the phases of branching were used.
