Gordienko T. Productivity of meadow-pusture lands depending on the methods of their improving, the composition of grass mixtures and fertilization on draining organic soils in the Forest-Stepe of Ukraine

Subject of inquiry - the formation of hay meadow mixed stands different on species composition and ripeness depending on fertilizer levels and methods of the improvement on the draining organic soils of the Forest-Steppe. The aim of investigations is the ascertainment of details of the formation sown grass stands of different ripeness and the development of the technology 0f the establishment of high-producing greenlands on the draining organic soils. The reserch methods are generally accepted. The regularities of the transformation of species structure of grass stands with different ripeness depending on the methods of meadows improvement? their fertilization and grass mixture composition are revealed. The technology of perennial grass different- ripening mixture growing at the moving and grazing combinated use is improved. It secures the even coming of green material in the system of grass conveyors and the obtaining of 70-95 hkg dry metter per hectare, 65-90 hkg feed units. The research results areintroduced at Panfyly Experimental Station of the Institute of Agriculture of the UAAS over an area 100 ha Economic effect is Hr 102 per hectare. The sphere of application - the agricultural production.
