The effect of the microbial preparations Diazofit and Polymixobacterin and mineral fertilizers on the yield of winter wheat have been studied. It was established that the presowing treatment of seeds with microbial preparations positively affects them, and increases the yield by 2.2- 2.5 t/ha, on average over the years of the re-search (2010-2015). As the result of such a treatment the plants are less affected by dark brown leaf spot, namely by 2.2- 4.6%. In the Western Forest-Steppe of Ukraine the profitability of elite seed production depended on the use of microbial preparations in combination with mineral fertilizers. A high level of profitability (91.0-93.0%) was achieved by the use of the phosphorus-mobilizing preparation Polymixobacterin (N30P90K90 and N30P45K90) and the total costs per ton of elite winter wheat seeds were 2.73-2.76 thousand hryvnia. When the nitrogen fixing prepa-ration Diazofit was used (N30P90K90 ), these indices were 82.0% and 2.38 thousand hryvnia/ton, respectively.
