Sukailo M. The productivity of kinds and varies of long-term grasses and their mixtures is on grey forest soils of Forest-steppe.

Subject of research - forming of different-ripe sown cereal and cereal-legume grass stands of different species and varieties composition. Objective of research - to determine the regularities of forming of different-ripe high productive hay-harvested sown cereal-legume and cereal grass stands depending on their species and varieties composition in the system of green or feedstock conveyors. Methods of research - field, laboratory, visual, measuring-weighing, calculating, analytical, economy-mathematical. For the first time in the conditions of northern part of Forest-Steppe the role of species and new varieties and mixtures of varieties of perennial grasses in forming of high productive different-ripe sown cereal-legume and cereal meadow grass stands under making grey forest soils alkaline is scientifically well-founded. The technology of fundamental improving degenerated natural fodder lands and making grey forest soils alkaline is developed that under conveyor incoming of green matter secures getting from 1 h 5-7 t fodder units with contents 130-150 gr of digested protein in one fodder unit. Author's scientific treatments are introduced during 2009-2011 yy on the farm "Adonio" Myronivskyy district and on the subsidiary farm of Kyiv-Pechersk Lavra Boryspilskyy district Kyiv region on total area of 222 h. Field of using - agricultural production.
