Abstract

The purpose. To determine productivity of efficiency of sowed cereal herbages depending on their species, sort structure and fertilizing in system of green (raw) conveyors on organogenic soils of Left-bank Forest-steppe. Methods. Field, laboratory, mathematical-and-statistical. Results. Productivity and terms of harvesting grasses and their mixtures of different terms of ripening on drained peat soils of Left-bank Forest-steppe are determined. Presence of herbages of different terms of ripening provides uniform receipt of cutted grass mass from the middle of May up to the end of September, as well as productivity of fields, which makes 7,5 – 13,2 t/hectare of dry weight, exchange energy — 72,6-125,1 t/hectare, and feed unit — 5,7 – 11 t/hectare. Conclusions. The best among early ripening grass herbages were the crops of orchardgrass of variety Kyiivska rannia 1 and meadow foxtail of variety Sarnenskyi rannii or their mixture with Awnless brome grass and meadow fescue. Among middle ripening grass herbages the best were fescue grass of variety Lyudmyla, reed canary grass of variety Sarnenska 40, Awnless brome grass of variety Arsen and mixture of meadow grasses with Awnless brome grass, fescue grass and reed canary grass.The highest productivity of late early ripening grass herbages is provided by adding into mixture Timothy-grass of variety Vyshgorodska, orchardgrass of variety Ukrainka and bent grass of variety Sarnenskyi piznya. Entering nitrogen fertilizers on drained peatlands is effective since the second year of use of grass herbages. Grass herbages on drained peatlands provide high fodder quality which is equated to quality of beans species. The content of raw protein in dry matter of the yield of different ripening types of grass herbages (on average over the years of research) was 14,5 – 16,0%, and security of fodder unit was 126 – 147 g.
