The investigation carried out in the years 1994–96 had to aim the analysis of morphological features perennial papilionaceaus plants and grass in pure sowing (6 objects) and mixture (3 objects). It was considerated the following morphological features: the number of stem per square metre, mass of single stem, number of leaves on the stem, leaves area of stem in square centimeter and two description of the stand: the number of leaves per square metre and leaves area index in square metre. The experiment was localited on the degraded chernozem, favourable for good growth of all plants. As result of carried out investigations it was confirmed that alfalfa headed in cuts and years of cultivation the greatest leaf area of stem and' stand in comparison to ather plant species. In results of species difference and method of sowing the all features was differentiated significantly. Interaction between features of investigated species and descriptions of the stand indicated to considerable greates effects of cut in comparison to the effects cultivation years, which appeared distincd only with respect to the leaves area index of stand. The greater density of plants stem cultivated in mixture in composition with cultivation in pure sowing proved about the co-existence between grass species and papilionaceous plants formed the phytocenosis of mixtures, particulary visible in mixture of alfalfa, clover, festuca and ryegrass.
