Polishchuk Mikhaylo Ivanovuch – Candidate of Agricultural Sciences, Associate Professor of the Department of Agriculture, Soil Science and Agrochemistry, Vinnytsia National Agrarian University (21008, Vinnytsia, Soniachna Str. 3, e-mail: polishchuk.mikhaylo@ukr.net).

The three-year research results of learning the effect of foliar fertilizations on grain productivity elements and quality indexes of spring barley sorts under conditions of Right-Bank Forest-Steppe on gray forest soils are presented in the article. Foliar fertilization of both plants sorts by the Quantum was contributed to formation of the greatest amount of productive stems on the plants every year of  research. The application of plants treatment during the vegetation period was contributed to increasing of ear grain weight. In this manner, the Quantum was provided the increasing of ear grain weight of the Adapt sort on 0,4 g or 26,7% in comparison to control variant, and  the Aeneas sort plants on 0,4 g or 28,6%, in average during the research years. All of the foliar fertilizations variants provided the yield grain increasing. The maximum grain yield, in average during the research years, was on the Quantum foliar fertilizations variants, in comparison to control variant the increasing was on 1,3 – 1,4 t/ha or 40,1-40,5%, depending the sorts. Plants foliar fertilizations of both spring barley sorts in the phase of stem elongation by the Quantum were provided the formation of the highest quality indexes of grain.
