Abstract
Goal. To study the patterns of formation of winter barley harvest for the components of the productivity of the ear. Methods. Laboratory, method of dispersion analysis. Results The productivity of separate elements of the structure of barley harvesting of winter brewing use under the influence of technological factors is investigated. The dependence of the number of grains and the mass of grains of the colossus on mineral fertilizers and seeds sowing norms was proved. Conclusions The ambiguous influence of technology factors on the implementation of the productivity potential of winter barley yields is established. On average, in the experiment, dynamic changes in the number of grains in the ear, depending on the seed rate of 300, 350, 400, 450 n./m2 were 24.9; 24.3; 23.5; 22.5 pc., Grains weight - 53.4 mg; 52.7; 51.8; 50.9 mg, respectively.

Key words: winter barley, yield, grain, number of grains in the ear, grains mass, mineral fertilizers, seed sowing rates.
