Kovtun K. 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.

Object - processes of formation ecologically and economic valuable specific structure of an agrophytocenosis from a perennial grasses and legume-grass mixtures, their efficiency and a forage quality, exhibiting of different rhythmics of an aftergrowing of grass mixtures of a different ripeness on prolongation of times of use by conveyer manufacture of forages. The aim is scientifically to prove and develop technological methods of increase of efficiency of perennial grass stands by conveyer manufacture of forages on arable lands of the Forest steppe. The methods - field, settlement, chemical, settlement-relative, mathematical statistics, dispersive, correlation, regressive. Novelty - The highly productive grass mixtures ripening in different times, for perennial and haying use in system of conveyer manufacture of forages are offered. Features of formation of efficiency of a grasses and legume-grass mixtures in dependence on influence organic and mineral fertilizers and times of their entering are revealed. Method of applications of biostimulus of growth are offered with the purpose of activization of symbiotic and associative nitrogen-fixing activity of bacteria and their influence on an increase yield of grass mixtures and improvement of a forage quality.
