Melnyk M. Improving the productivity of pastures depending on the species composition and the intensity of their usage on the Right Bank Forest

The research object - a formation process of species structure and productivity of the same time maturing grass mixtures, pasture forage, quality parameters depending on the species composition and modes of alienation. The purpose of research - optimization of species composition and increase the productivity of different time maturing perennial pasture grass mixtures in conditions of different modes of usage on the Right Bank Forest Steppe of Ukraine. The methods - visual; weight; biochemical; statistical; comparative-calculational. In the dissertation are established performance parameters of sown herbages that are maturing at different times and nutritional feed value because of different regimes of pasture usage of grass mixtures.Are improved the models of perennial grass-legume herbages for the creation of cultivated pastures. Were further developed ideas about the formation of maturing at different times herbages by the relevant parameters of productivity at their cyclical pasture usage that is providing a systematic, daily intake of high-quality pasture feed during 162 days. The researches were implemented in the farms of Vinnytsia and Khmelnytsky regions on the area of 15 hectares. Sector (branch) - agriculture.
