Povidalo V. Productivity of perennial grasses that depends on fertilizers on the dark gray podzolic soil.

Object - forming feed and seed productivity of perennial grasses depending on fertilizers, chelated complex forms microelements and their interaction. Purpose - to establish patterns of forage and seed productivity of Dactylis glomerata, Festuca pratensis, Bromopsis inermis depending on fertilization to produce stably high yields of high quality products. The methods are field and laboratory using visual, measuring and weighing and calculation , analytical and economic- mathematical. The peculiarities of the growth and development of plants, forming feed and seed productivity and quality of new varieties of biomass Dactylis glomerata, Festuca pratensis, Bromopsis inermishryastytsi in dark gray podzolic soil depending on fertilization. Improved technology elements of the fertilization of perennial grasses based on economically and energetically feasible doses basic nutrients fertilizers that ensure 1 ha 4.7 - 5.1 t / ha dry weight and 0.28 - 0.33 t / ha seed. Scientific research implemented in 2012 in JV " Mateykivinvestahro " Bar district of Vinnitsa region of 80 hectares of which 25 hectares - seed crops. Areas of use - agricultural production.
