The article presents the results of the study of the influence of mineral fertilizers, green manure,seed treatment with biopreparations and spraying of crops with Biocomplex-BTU on the parameters ofproductivity and affection of two varieties of wheat by the mildew of plants. It has been established thatpre-seeding bacterization contributes to the increase of yield by 0.09-0.34 t/ha, depending on thebiopreparation and fertilization. Under the action of mineral fertilizers alone or in combination withgreen manure, the yield increased by 1.74-2.21 t/ha, compared with the variant without fertilizers andwithout inoculation. The treatment of winter wheat crops by Biocomplex-BTU promotes yield increase by0.19-0.34 t/ha, depending on the fertilization and inoculation of seeds. Under inoculation of seeds andtreatment of crops with biopreparation, the number of productive stems and grains in the spike increases,while the weight of 1000 grains is predominantly reduced.Under use of fertilizers, specified parameters increase significantly. The most effective is the use ofbiopreparations without fertilizers.
