英语. In course of the research there were studied productivity and nutrient intake of various species of perennial grasses in haylands use. The research was realized in the conditions of the Republic of Belarus in 2012-2013 on a trial field of Grodno Zonal Institute of Plant Growing, Shchuchin. Soil of the trial field was sod-podzolic sandy loam, underlain at a depth of 0.7 m by moraine loam. Agrochemical characteristics of arable soil horizon: humus - 1.2-1.3%, pH - 5.9-6.0, content of P2O5 - 230-250 and K2O - 150-160 mg/kg of soil. As a result of realized research there were revealed that among the main cultivated middle-ripening types of grasses festulolium had one of the highest yields of dry matter (5.65 t/ha) and output of fodder units (4.33 t/ha). A distinctive feature of feed produced from herbage festulolium was that even with the aging (with the transition from the phase of the output end of the tube - the beginning of earing before flowering) the amount of fiber was at an optimum level 20.8-27.9% and a high content of sugars -18.09-19.77%.
