Shtakal V. Productivity of cereal meadow grass canopies of different species and varietal composition on drained organogenic soils of Left-Bank Forest-Steppe

The object is the process of intensify of cultivation grass canopies of different ripening type and the organization of the hay conveyor on their use on drained peatlands of the Left-Bank of Forest-Steppe. The aim of the research was establishing the ecological and biological laws of the formation of different ripening time high-yielding hay mowing cereal of grass canopies depending on their species and varietal composition and fertilization in the system of green (raw) conveyors on organogenic soils of the Left-Bank of Forest-steppe. Methods - field, laboratory, visual, measuring-weight, calculation, chemical, mathematical-statistical. For the first time in the conditions of the Left-Bank of Forest-Steppe the ecological-biological and phytocoenotic activity of new varieties of perennial grasses was established, that made it possible to select the most productive of them, that providing 9-14 t / ha of dry mass from 1 ha or 6-10 t / ha of fodder units in system of green (raw) conveyor. The main results of the research were introduced in 2016-2017 at the farm PE "Sosnova" Pereyaslav-Khmelnitskyi district of the Kyiv region on the area of 140 hectares, that ensured a net profit growing of 3500-4100 uan / ha. The field of using is agricultural production.
