In dry conditions single-species alfalfa crops exceed the grass and alfalfa-grass mixtures by 94,1 and 10,7–28,4 % respectively. One and two-year-old clover-grass and alfalfagrass mixtures were more productive than alfalfa mixtures with bird’s-foot trefoil and single-species stands of alfalfa.

Keywords: alfalfa, red clover, bird’s-foot trefoil, grass mixture, yield.

A comparative study of the length of vegetation and the interphase periods, wet and dry matter accumulation, seed and protein yield was carried out on narrow-leafed lupin (Lupinus agustifolius L.) cv. Сrystal, soybean (Glycine max (L.) Merr.) cv. Mageva and faba bean (Vicia faba L.) cv. Maria. Th e fi eld experiment has been conducted for fi ve years at the Field Experimental Station of RSAU-MTAA. Th e variability of these parameters is shown as dependent on the species and cultivars together with different weather conditions of the vegetation period.

Keywords: narrow-leafed lupin (Lupinus angustifolius); soybean (Glycine max (L.) Merr.); faba bean (Vicia faba L.); wet and dry matter accumulation, seed productivity, protein yield.
