The justification of agro-energy efficiency of growing new high-yielding drought-resistant varieties and types of perennial grasses, such as intermediate Wheatgrass, elongated Wheatgrass and yellow alfalfa, which provide a positive effect of interaction of legume-cereal grass mixtures and single-species crops that are resistant to abiotic factors while improving hayfields and pastures of the arid zone, is presented. All studied grass mixtures and single-species crops of yellow alfalfa had a high annual yield of gross (21.7–48.7 GJ/ha) and exchange energy (13.5–32.1 GJ/ha) and provided the production of full-fledged feed.
