The article presents the results of research on the study of the patterns of influence of biologized fertilizer systems on the productivity and quality parameters of winter wheat grain. Aim of the work: to find out the characteristic features of the influence of biologized fertilizer systems on the formation of winter wheat yield and its quality parameters. To achieve the set goals, the following methods were used: physiological and biochemical – determination of gluten and protein content in grain. Account of the elements of the crop yield structure and biological productivity was conducted according to generally accepted approaches. It has been established, that biologized fertilizer systems have a significant impact on the formation of crop yield structure elements and grain quality of winter wheat. The most effective in this direction were noted the fertilizer systems with the following composition: legume straw + N90P60K60 with the addition of a biostimulant (BS) and humus fertilizer (HF) or the treatment with a chelate fertilizer (CF) on the specified background. In the case of the above mentioned conditions, there were a simultaneous increase in the biological yield to levels of 506–509 g/m2 , increase in the content of the gluten and protein in winter wheat grain to 51.9–56.2 % and 11.0– 11.7 %, respectively. The results obtained showed, that the use of bioeffectors (BS and HF or CF) in fertilizer systems contributes to the improvement of the bioproductivity traits (yield and grain quality) of winter wheat.

Keywords: biologized fertilizer systems, winter wheat, elements of the crop yield structure, gluten and protein content.
