Kovtun E.P. Scientific substantiation of technological methods of creation of highly productive perennial grass stands by conveyer manufacture of feeds on arable lands of the Forest steppe. The manuscript.
The thesis for the scientific degree of the Doctor of Agricultural Sciences on a specialty 06.01.12 - forage production and grassfarming. - Vinnitsa State Agrarian University, Institute of feeds UAAS, Vinnitsa, 2006.
Approaches of intensification of grass forage production on arable lands on the basis of selection of perennial cereal and legume-cereal grass mixtures with different mowing rates, increase of their productivity when applying complex agro-technological measures are theoretically substantiated and carried out in the thesis.
Rates of mineral fertilizer application in cereal and legume-cereal mixtures under natural conditions of soil provision with moisture and irrigation, terms of nitrogen fertilizer application in legume-cereal mixtures and prolongation of longevity of legume grasses in combined sowings with cereal components are scientifically substantiated.
The role of different varieties of legumes in the increase of productivity of legume-cereal mixtures, forage quality and its energy nutrition value are determined.
Technological methods of the use of bacteria preparations and biostimulus of plant growth to intensify the process of nitrogen fixation in a root zone of legume and cereal grasses, more intensive receiving of biological nitrogen by plants, productivity increase of legume-cereal grass mixtures, forage quality are carried out.
The expediency of developed methods of creation and utilization of grass stands of different ripeness are proved by high indices of bioenergetic and economic efficacy.
Conducted researches enable to get conveyer receipt of high quality green forage with the duration of 120-160 days and raw material for hay and haylage preparation.
Key words: grass mixtures of different ripeness, fertilizers, legume grasses, productivity, forage quality, bacteria preparations, biostimulus of plant growth, exchange energy, conveyer.
