aref2 The purpose of the studies was to raise nutritional value of vegetative raw material of a winter rye for laying-in of high-quality voluminous forages (green weight, grain-haylage) and grain-forage by sowing of rye with winter vetch. Three field experiences were conducted: at cultivation of vetch-rye mixes for green weight and grain in three rotations (in 2004, 2005 and 2006), and also for grain-haylage mix - in two rotations (in 2008 and 2009). After such winterhardy varieties of winter vetch as Lugovskaya 2 had been developed, its combined sowing with winter rye provides the stably high productivity of high-protein fodder mass with cultivation for feed purposes. At early use of vetch-rye mixes for green forage the optimum seed rates are 3.6-4 million/ha for winter rye Falenskaya, 1.6-2 million/ha for winter vetch - Lugovskaya. In this case the output of exchange energy is 65.7 GJ/ha, of protein content is 733.2 kg/ha, and digestible protein content is 144.9 gram per 1 fodder unit. Cultivation of vetch-rye mixes for grain-haylage is perspective at seed rates 4.8 million/ha for winter rye, and 0.8 million/ha for vetch; for increase a crude protein crop they are 4.2 and 1.2 million/ha correspondingly. Harvesting of such a mixture at phases from milk-wax up to wax ripeness of winter rye grain provides an output of exchange energy more than 70 GJ/ha and protein yield - from 413 to 493 kg/ha.
