The analysis of literary sources found that spring barley is an important cereal crop for growing in Ukraine and its use in world agriculture. In the article the theoretical and practical ways of solving the scientific problem of passing the growth processes and forming the productivity of barley and influencing them on non-root infusions are presented in the article. The results of the study on the formation of high yielding barley crops by the use of new perspective varieties, mineral nutrition of plants on gray forest soils under the conditions of the forest steppe of the right bank. The results of research on the formation of the crop, its structure and the positive reaction of varietal barley varieties are described. The results of the study of the effectiveness of the use of foliar fertilizers with fertilizer N60 Karbamide in the phase of plant release in the tube and the complex fertilizer “Nanovit Macro” in the phase of ear eruption are presented. Thus, in these experimental variants, the maximum yield was noted, in the Vodograi variety – 6,93 t/ha, and in the Gladys variety – 5,74 t/ha. Two-year results have been proved, the growth of biometric indicators due to the elements of intensification occurred in the varieties Gladys and Vodograi. It was established that the largest length of the ears (16,3 cm) and the number of grains (46,2 pc.) In the ear, and the mass of 1000 seeds (47 g), was noted in the Vodograi variety in the experimental version, where the extracorporeal fertilization was carried out with “Karbamide” and complex fertilizer “Nanovit Macro”.
