An important task for the Republic of Belarus is the expansion of pulse agrocoenosises of perennial grasses cultivation, less demanding to the growing conditions (drought persistence, the intensive use). The article discusses the cultivation of alfalfa (Medicago sativa) and grass mixtures in the south-east zone of Belarus. The experimental setup: 1) alfalfa in pure form; 2) alfalfa, 50%; timothy grass (Phleum pratense), 25%; red fescue (Festuca rubra), 15%; white clover (Trifolium repens), 10%; 3) alfalfa, 60%; fescue, 15%; red fescue, 15%; clover, 10%; 4) alfalfa, 30%; sainfoins (Onobrychis), 40%; fescue, 15%; red fescue, 15%; 5) alfalfa, 30%; timothy, 20%; meadow fescue (Festuca pratensis), 20%; tall fescue (Festuca arundinacea), 10%; bird's-foot trefoil (Lotus cornicutus L.), 20%. Data on productivity, nutritional content by cuttings for four years use of mixtures based on alfalfa planting are stated. Thus, in our studies on the production forage crop, dry matter, yield of digestible protein and essential amino acids it was impossible to give preference to a particular grass mixture.
