The article presents the results of research on the influence of fertilization and pre-sowing treatment of seeds with fulvic-humic fertilizer StymOrganic Multicomplex Grain, Bionorma azot and Yarylo Aktyvnyi start PRO on the formation of individual elements of productivity of winter wheat of the Estatefeta myronivska variety in the conditions of the Carpathian region. The agrometeorological conditions of the winter wheat vegetation periods and their influence on plant germination and overwintering were analyzed. It was established that field germination during the years of the study in the control plots was on average 88.0–88.6%. Pre-sowing treatment of seeds contributed to the growth of this indicator. In particular, seed treatment with fulvic-humic fertilizer StymOrganic Multicomplex Grain (1 l/t) increased the indicator by 0.6-1.3%, the drug Bionorma nitrogen (1 l/t) – by 0.4-1.9%, Yarylo Aktyvnyi start PRO (1.0 l/t) – by 0.5-1.3%. Accordingly, the indicated variants had a greater number of plants per 1 m2 in the fall (within 445-450 pcs) and after wintering (427-433 pcs/m2). A positive effect of nitrogen fertilizers (N120 and N150) and pre-sowing seed treatment on the increase in the number of stems on the plant and synchronously developed spikelets in the ear was noted
