Zabarnyy O. Feed productivity of alfalfa depending on the cover crop, mineral nutrition and modes of use under conditions of the right-bank Forest-Steppe

Objects which are researched are the processes of the formation forage productivity of alfalfa depending on the cover crop, mineral nutrition and modes of use under conditions. The goal for our research is the finding dependences of forming forage productive of alfalfa depending on the cover crop, mineral nutrition and modes of use under conditions of the right-bank Forest-Steppe. Methods of the research: visual and weight; physiological; biochemical; statistical; rather. The results of research on the study of peculiarities of growth, development and formation of photosynthetic, symbiotic and feed productivity of alfalfa depending on the influence of the cover crop, mineral nutrition and modes of grass stand use are presented in the dissertation, and economic, bioenergy evaluation and assessment of the technology competitiveness are stated. Obtained and generalized material makes it possible to recommend the production of the most economically profitable and competitive technology for alfalfa cultivation under conditions of the right-bank Forest-Steppe, which provides formation of the leaf and stem mass at the level of 42,05-48,16 t/ha in the second and 39,38-42,36 t/ha - in the third year of life, while dry matter yield was 9,90-11,34 and 9,26-9,95 t/ha respectively. Science researches have been passed the stage agronomics forming of the Vinnytsia region ("Oleksandrivs'ke") and Khmelnitskiy region ("Pasichna") at the general area of 45 hectares. The sphere of using is the agriculture.
