Ivanov "Ascania-Nova" - National Scientifical Selectional-Genetics Center of Sheep Breeding popup.description2 The object of research is pasture-haying agrophytocenoses of perennial grass species. The purpose of research - to develop the models of agrophytocenosis, which can be used for pasture-haying and restoration of natural forage lands south Ukraine, based on selected drought-resistant and resistant to adverse conditions grass species with high economic and useful properties. Methods of research - field and laboratory experiments. The most promising models of agrophytocenosis, based on a new introduced accession of forage grasses steppe ecotype, have been created for restoration of natural forage lands. Sowing in a mixture of wild rye Sitnikov with sainfoin provides an average yield of green mass 126.6 kg / ha with a yield of 42.4 c / ha of dry matter, 26.3 c / ha fodder units and 3.07 kg / ha of digestible protein; rump - 163.7 kg / ha, 49.2 kg / ha, 36.2 and 3.41 kg / ha; wheatgrass - 130.5; 34.9; 28.1 and 2.84 kg / ha; bluegrass - 169.7; 44.7; 32.4 and 3.76 kg / ha and fescue grooved - 33.7; 10.6; 7.1 and 0.81 kg / ha of green mass respectively. Cost price of green mass and level of profitability growing perennial mixtures are 3,14- 3,62 UAN / c and 22,7-64,4%. Scope of use is the environmental formations and livestock farms of the southern region of Ukraine. The effect of this work is the conservation of nature.
