Abstract
Goal. To study the influence of predecessors, the timing of sowing, and to evaluate varieties on the yield of winter wheat grains. Methods. Field and statistical-dispersion analysis. Results The results of research of separate elements of the technology of winter wheat cultivation are covered. The dependence of grain yield on predecessor, sowing dates and varieties is proved. Conclusions The yield of wheat grain on a black steam makes up 5.25 t / ha on average, according to the predecessor, perennial bean grass - 4.81 t / ha. Under the second sowing period, the grain yield was 5.20 tons / ha, and the first - 4.86 tons / ha. In the estimation of varieties, on average, the yield of the Bila Tserkva half-carcass variety was greater than that of the Tsarivna variety at 0.32 t / ha.

Key words: winter wheat, grain yield, predecessors, sowing dates, varieties.
