Matkovska M. The yield of winter barley varieties depending on growth regulators, dose rates of fertilizers and fungicides under conditions of the Western Forest-Stepp

The object of research – the processes of growth and development, the formation of yields and quality of winter barley grain depending on variety, growth regulators, fungicidal protection and fertilizers. The goal of research is to investigate the dependences of the formation of the yield of intensive varieties of winter barley in the conditions of the Western Forest-Steppe depending on the complex influence of mineral fertilizers, morphoregulators and fungicides. Methods of research - field, visual, chemical, laboratory, computational weight, computational comparison, dispersive, correlation and graphical depiction of the data of the research results. In the dissertation, the author presents results of the research on studying of dependence of formation of the yield of productivity variety of winter barley in the conditions of the Western Forest-Steppe depending on complex influences of dose rates of mineral fertilizers, morphoregulators and fungicides are resulted. The peculiarities of photosynthetic activity of plants depending on the influence of growth regulators, mineral fertilizers, fungicides and studied varieties are revealed. The best combinations of morphoregulators on different varieties of winter barley in the conditions of the Western Forest-Steppe have been identified and the influence of growth regulators and features of varieties on the formation of yield components has been established. The influence of fungicides, fertilizer rates on the development of diseases, the formation of indicators of the yield components of winter barley was studied. The effect and interaction of mineral fertilizers and fungicide protection, the influence of growth regulators on the yield of barley varieties, statistically processed data and analysis and generalization of the results. The influence of elements of technology on biochemical indicators of barley grain quality is investigated. The evaluation of economic and bioenergy efficiency of improved elements of winter barley cultivation is carried out. The improved technology of winter barley growing has been tested in the production process at the farms of Khmelnitsky region on the area of 130 ha. The branch of use – agriculture.
