Satsyk V. Selection of species and varieties of perennial grasses and their mixtures are identified providing high productivity of hay-moving on drained dernocarbonate soils of Western Polesye of Ukraine.

The conversion process and the regularities of ecologically and economically valuable specific structure formation of agrocoenoses from perennial grasses, their productivity and the feding quality. To reveal the best species, varieties, grass and strain mixtures for the establishment of high-producing hay meadow mixed stands on the drained soddy calcareous soils of the western Ukrainian Polissia. . The research methods are generally used. The agroeconomic assessment is given and the best cereal and legum grass species, their varieties of home and foreign breeding and grass and strain mixtures for the establishment of high-producing meadow stands of mowing use are revealed. The recommendations concerning the selection of cereal and legume-grass and strain mixtures for the establishment of meadow lands on the drained soddy calcareous soils of the western Ukrainian Polissia When removing of arable land from use are developed. The scientific developments are applied to production over an area 85 ha at t he farms of the Volyn Region. The application of developments promotes the increase of operating profit by 75% and essentially raises technology profitability of the establishment of sown meadows. The agricultural production.
