According to the results of our own researches and the analyzed literature sources, it is established that the use of pre-sowing treatment of seeds and crops of alfalfa with sowing stimulants and microfertilizers improves the conditions of growth and development of culture and improves individual productivity. Agrotechnological techniques for growing alfalfa crops under sowing have been improved through an optimized system of seed treatment with growth stimulants for crop fertilizers with a complete set of macro and microelements. A close correlation-regression relationship was established between the yield of alfalfa seeds and: plant density, plant height and individual seed productivity of one plant. The highest seed yield from one plant was recorded on the variant of sowing treatment with the growth stimulator Saprogum in the branching and budding phase + fertilizing of the budding phase by the microfertilizer Vuxal - 1.0 g, which is 11.0% more than the variant without sowing with stimulants and microfertilizers. Comparison of the magnitude of the seed output from one alfalfa plant under different combinations of growth stimulants and microfertilizers showed that the combination of sowing with a growth stimulants Lucis in the branching and budding phase + fertilizing the crop in the budding phase with microfertilizers of sowing treatment with a growth stimulant Saprohum in the branching and budding phase + fertilizing of the budding phase by the microfertilizer phase Vuxal. The highest yields of alfalfa seeds were obtained by sowing variants with the Lucis growth stimulants and microfertilizers «Urozhay bobovi» was 0.48 t/ha. The expected results of the research are aimed at increasing the level of realization of the crop varietal potential of perennial grasses, namely, alfalfa, increasing the profitability of its production in combination with environmental and social effects
