Influence of the mixture of Trifolium pratense L. and Medicago media Pers. with Festuca arundinacea Schreb. on yield and nitrogen content was studied in field experiments. First year of yielding showed that mixtures containing red clover significantly increased the yields in comparison with these obtained for M. media containing mixtures. In the last case the yields increased significantly in second year. Third year yields from T. pratense fields decreased. Total nitrogen contents was low on the fields without papilionaceous plant
