The results of research on the assessment of the forage and environment-forming role of legumes and cereals grass and grass mixtures with their participation are presented. It is established that adaptive and stable phytocenoses based on such grasses as yellow alfalfa, yellow melilot, sainfoin, wheatgrass, Wheatgrass during haymaking use form on average 10.3–14.5 t/ha of green mass, 2.0–3.1 t/ha of dry matter, 280–390 kg/ha of raw protein and 12.1–18.8 GJ/ha of exchange energy in the arid zone in the southern of Russia.
