Treatments of the investigation: factor A – variety 1) 'Kovas DS' 2) 'Olivin' factor B – seeds ratio 1) 1.5 million seeds per ha, 2) 2.5 million seeds per ha. Best crop emergence 3rd and the 10th days of germination set 'Olive' crop varieties, sowing 2.5 million seeds per ha. Winter wheat 'Kovas DS' breed plants tillering better, and stand density of vegetation at the end of the fall was bigger than the 'Olive' variety. Better to over wintering in winter wheat 'Kovas DS' to breed plants. The largest winter wheat grain yield (7.64 t ha-1) set 'Kovas DS' crop varieties, sowing 1.5 million per seeds ha -1. The highest yield of winter wheat straw (5.85 t ha-1) set 'Olive' crop varieties, sowing 2.5 million seeds per ha.
