Mazurak I. Oat productivity filmy and naked depending on the elements of cultivation technology under conditions of the Western Forest-Steppe

The object of research – the process of formation of the yield and quality of grain of the film and naked oat varieties depending on the elements of the growing technology in the conditions of the Forest Steppe of Ukraine. The goal of research is to assess the process of growth and development of plants of film and naked oat varieties and to obtain their yields in the conditions of the Western Forest Steppe depending on the biological potential of the studied varieties, sowing rates, different systems of fertilization and level of intensification. 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 the study of peculiarities of impact of the variety, sowing rate, mineral fertilizers and agents of plant protection on formation of oat productivity in the conditions of the Western Forest Steppe. The work determines the dependence of formation of oat photosynthetic productivity referring to the impact of the studied factors. The research defines close correlation relations and regression dependences between the technological instruments and oat productivity, argues economic and energy efficiency of the technology of oat growing on the base of mineral nutrition optimization. The improved technology of oat growing has been tested in the production process at the farms of Rivne region on the area of 65 ha. The branch of use – agriculture.
