Fostolovych S. Feed productivity of spring vetch depending on the influence of rates of mineral fertilizers and foliar nutrition under conditions of the right-bank Forest-Steppe of Ukraine

Object of research - processes of growth, development and formation symbiotic, photosynthetic, grain and carrying capacity of plants of a vetch of dependence on impact of an inoculation, rates of mineral fertilizers and leaf-feeding dressings. The work purpose consisted in revealing of dependences of formation of a grain yield of a vetch spring from rates of mineral fertilizers and leaf-feeding dressings in the conditions of right-bank Forest-steppe of Ukraine. Methods of researches - Field in a combination with visual - for definition of interaction of object of researches with natural and investigated factors; weight - for definition of productivity of plants and crops; biochemical - for definition of nutritiousness, a forage chemical compound; physiological - for definition of photosynthetic and symbiotic activity of crops of a vetch spring; statistical methods: dispersive, correlative regression - for definition of reliability of data, correlation dependences; settlement-comparative - for definition of economic, power efficiency and an evaluation of technologies of cultivation on competitiveness. In dissertational work results of researches are stated: in the conditions of right-bank Forest-steppe it is revealed dependences of impact of rates of mineral fertilizers and Kristalon leaf-feeding dressings on fodder productivity of a vetch spring. Dependences of formation of symbiotic and photosynthetic productivity are established. Positive impact of rates of mineral fertilizers and leaf-feeding dressings on formation of indicators fodder qualities of grain of a vetch spring is proved. It is spent economic and a biopower evaluation of models of technologies of cultivation of a vetch spring and are defined their competitiveness. "The method of cultivation of a vetch spring" in 2011 introduction of complete scientific and technical development is spent to BPF "Oleksandrivske" on the area of 15 hectares, and in Branch "Scientific innovative technological centre" of Institute of Feed Research And Agriculture of Podillya NAAS on the area of 30 hectares. Use sphere - agriculture.
