Kamenshchuk B. Feeding productivity of corn hybrids depending on influence of processing methods cultivation under the condition of Lisostep

The object of study - the processes of growth, development and formation of yield, feeding value of maize hybrids of different maturity groups, depending on the planting and growing conditions. The purpose of this study was to identify the relationships that form the feeding performance of different maize hybrids and indicators of their nutritional value from the influence of planting and forest-steppe hydrothermal conditions. Research Methods: field; weight; physiological; biochemical, statistical; settlement. This thesis presented the results of investigations of the peculiarities of formation of grain productivity of different hybrids of corn and feed their value depends on the influence of planting and agro-ecological conditions of growth. Defined productive action and the coefficients of digestibility of corn grain in feeding pigs. Shows a comprehensive assessment with respect to selection of corn hybrids for forage for the direct and indirect signs. Evaluated an economic and energy of technologies for growing corn. Obtained and the material makes it possible to recommend the production of maize hybrids and technological elements in their cultivation, are capable of providing output feed units at 10,85-13,18 t/ha with a crude protein content greater than 10% regardless of the province, forest-steppe zone. Conducted production testing and implementation of research in agricultural enterprises of Vinnitsa region. The total area of the introduction of more than 5000 ha. Scope of use - agriculture.
