The article analyzes the current state and trends of cultivation in the South of Ukraine of such valuable food, fodder and technical culture as spring barley. An analysis of statistical data on the cultivation of this crop shows that its area during the last 15 years declined in Ukraine by 56%. Consequently, the interest of commodity producers in the cultivation of barley has recently been dying, while the largest crops are preserved mainly in small commodity producers. The article outlines the ways of influencing the implementation of biological potential of culture by introducing into production of modern and competitive cultivation technologies. Such technologies should be based on selection of highyielding varieties adapted to the conditions of the South of Ukraine, and optimization of nutrition through the use of modern growth regulators, biologics and organo-mineral fertilizers. The article describes the variants of the use of phosphoric-potassium and nitrogen fertilizers in the growing of barley in the framework of conventional cultivation technologies. Considerable attention is paid to the efficiency of the implementation of energy and resource-saving technologies in the field of agro-industrial complex. So, the use of plant growth regulators is one of the modern measures to increase the yield of grains of barley. The key evidence in the article is the results of a field experiment, which was laid in the years 2016-2017 for the growth of barley barley with the use of growth regulators, organo-mineral fertilizers and biopreparations, by means of foliar nutrition. On the basis of the analysis in the article, the state of growing barley and possible ways of increasing the yield of grain are concluded that on the basis of analyzed statistical data on the indices of crop areas and yield of barley grain in Ukraine, analysis of literary sources on the results of the use of growth regulators, organo-minerals fertilizers and biopreparations, it was concluded that it is expedient to use them when growing the research culture and the relevance of further research into this on a line
