The purpose. To study influence of biological preparations and their elements in biologization of cultivation of winter wheat after such predecessors, as bare fallow and winter mustard, and also productivity, quality of grain on different backgrounds of importation of basic mineral nutrition. Methods. General scientific: field experiments, laboratory (physicochemical parameters of grain), calculation-relative and mathematical (dispersing). Results. It is determined that at use in technique of growing winter wheat of some biological preparations on different backgrounds of basic mineral nutrition productivity raises on 0,08-0,25 t/hectare and quality of grain from the 5-th to 3-rd class treats to food one. Conclusions. On the basis of probes it is determined that for deriving stable high and quality yield under the basic cultivation of soil it is necessary to deposit complex fertilizers in doze NPK 32 , NPK 64 and to inoculate seed grain with biological preparations on the basis of nitrogenfixing, phosphate-mobilizing, potassium-mobilizing bacteria with the use of organomineral fertilizers, microelements on the basis of chelates, biostimulus, biofungicides, vitamins, amino acids, betaine, spores of mycelium of fungus Trichoderma lignorum, bacterial crop Bacillus subtilis. Use of elements of biologization of cultivation of winter wheat on the background of different predecessors and mineral nutrition for martempering productivity and quality of grain of winter grain crops in conditions of South Steppe of Ukraine is perspective.
