Abstract Nowadays due of the world population growth, the demand for agricultural products is also growing. To obtain good meat and dairy products, high-quality feed for farm animals is necessary. Legume-gramineous perennial grass mixtures are used to improve fodder lands. Our experience included a test of 9 variants of legume-gramineous grass mixtures, where 6 types of grasses were used: red clover, alfalfa (legumes), meadow timothy grass, orchard-grass, smooth brome-grass, meadow fescue (cereals). The experiments were carried out in four repetitions on the lands of hay and pasture use with the use of fertilizers; there were carried out phenological observations, biometric measurements, and determination of the botanical composition. In herbage from hay fields the smooth brome-grass dominated, and in herbage from pastures the orchard-grass dominated. The proportion of non-sown grass species reaches 26.3-32.7 % in three-component grass mixtures with meadow timothy grass. Meadow fescue and meadow timothy in terms of growth rate, reactions to nitrogen application were inferior to the orchard-grass and smooth bromegrass, which led to their oppression and displacement from the herbage. The best density of plant standing per 1 m 2 was noted in the orchard-grass and smooth bromegrass, the smallest - in meadow fescue and alfalfa.
