Medicago sativa is one of the most productive legumes, which provides high protein
production. Application of the biostimulant and microfertilizers is quite relevant and effective.
Theoretically substantiates and presents ways to solve the scientific problem of formation of
Medicago sativa productivity and the impact on them of seed treatment and foliar nutrition, taking
into account the conditions of the Forest-Steppe right bankof Ukraine. The research was
conducted in the research field of Vinnytsia National Agrarian University in the village of
Agronomichne, Vinnytsia district during 2016–2018. Sinyukha variety was sown (2010). There
has been established that the use of pre-sowing treatment of seeds and crops of Medicago sativa
with biostimulant and microfertilizer improves the conditions of growth and development of the
crop and increases individual productivity. On the researches it is established that fodder
productivity of Medicago sativa sowing is provided by application of biostimulators of growth
and microfertilizers on crops, genetic potential the culture realized as much as possible on the
2nd year of cultivation. The effect of growth stimulants on Medicago sativa productivity was
defined and the optimal combination of macro- and microelements in modern complex fertilizers
was determined, which contributes to the maximum possible yield of Medicago sativa green
mass. New technological regulations for the use of bioorganic preparations and components in
the technological scheme of Medicago sativa cultivation have been developed. It was found that
on average for three years of vegetation of Medicago sativa sown on gray forest soils in the
Forest-Steppe Right Bank, the highest yield of seeds and green mass provides the option of
treatment with biostimulator Saprogum® and microfertilizer Wuxal®. Creating optimal conditions
for mineral nutrition for Medicago sativa plants through the use of bacterial fertilizers and foliar
nutrition contributed not only to the formation of high grain yields, but also significantly
improved biochemical parameters and, consequently, increased crude protein content in grain,
which is important for solving the problem of vegetable protein and balancing the diets of farm
animals. The research results are aimed at solving current problems of technological renewal and
development of agro-industrial complex on the basis of development of bioorganic models of
varietal technology of Medicago sativa cultivation with orientation at the level of adequate arable
productivity and climate fertility
