This article presents the results of studies of the effectiveness of the use of biological products in winter wheat crops. The positive effect of pre-sowing seed inoculation with biological products Azotofit and Help Growth on the germination capacity of winter wheat seeds of the Skagen variety has been established which was 3-4% higher than the control and contributed to an increase in the number of nodal roots by 56% and 50%, respectively, the plant density was 13-9 pcs / m2 more than in the control. In the variants Azotofit and Help Growth, productive tillering was higher by 0.3-0.2 stems / plant. compared with the control, and the infestation of plants by root rot was 6.6-4.7%, respectively. It was established that an increase in winter hardiness as a result of pre-sowing inoculation of winter wheat seeds, which was 93.2-94.5%, respectively, which was 2.7-4% higher than the control indicator and overwintering of plants, which was 546-521 pcs / m2, which 111-85 pieces / m2 more compared to the control. The combination of pre-sowing inoculation with biological products Azotofit, Help Growth and feeding with Organic Balance (during spring tillering) had a positive effect on the bushiness of plants and their productivity, which, in the variant providing for pre-sowing inoculation of seeds with the biological product Azotofit and feeding with Organic Balance, was 580 which is 102 pcs / m2 higher than the control indicator. The use of the studied preparations contributed to the better spring tillering of winter wheat plants and the number of productive stems, in particular, the combination of pre-sowing inoculation, respectively, with the biological products Azotofit and Help. Growth and feeding Organic balance (during the spring tillering period), the number of productive stems is 535-540 pcs / m2, which is 112-117 pcs / m2 more than in the control. The use of the studied biological products had a positive effect on the elements of the structure of the crop, in particular, an increase in the number of grains per spike, the mass of grain per spike and the mass of 1000 grains was noted, which ultimately contributed to obtaining the highest yield of winter wheat, which in the application of Azotofit and Help Growth was 5.64-5.82 t / ha, respectively, which is 0.48-0.66 t / ha more than in the control. When feeding in the tillering phase with Organic, the yield balance was 5.63 t / ha, which is 0.47 t / ha higher than in the control. With a combination of presowing inoculation, respectively, with the biological products Azotofit and Help Growth and feeding Organic balance (during the spring tillering period), the yield was 6.21-6.38 g, which is 1.09-1.22 t / ha more than in the control.
