Article highlights the results of research of the effect of pre-sowing seed treatment with polyfunctional chelate fertilizers on growth and development of winter wheat. The research was conducted in the research field of separated department “Agronomic research station” of National university of life and environmental sciences of Ukraine. Field and laboratory experiments were conducted due to approved methods. Maximum grain yield was formed in variant of fertilization “Base (P90K120) + N30 (ВВСН 25-26)+N30(ВВСН 31-32)+N30 (ВВСН 68-69) and pre-sowing seed treatment with mix of Avatar-1 and Jodis-concentrate. There are 7.37 t_ha in cultivar Samurai and 7.16 t/ha in cv. Bohemia of grain yield formed in average in 2018-2020. Significant effect on grain yield was observed under application of nitrogen fertilizers on BBCH 25-26, BBCH 31-32 and BBCH 68-69. Pre-sowing seed treatment with mix of Avatar-1 and Jodis-concentrate increased yield from 11-13 % on variants without nitrogen fertilizers till 15-20 % under combine application of fertilizers. Seed treatment by Avatar-1 increase yield on 8-10 %, but effect of Jodis-concentrate is slight lesser (2-4%).
