The research was established as a completely randomised block design with the four replications, and was conducted in the years between 1995 and 1997 at the Haymana İkizce Experimental Station of The Research Center for the Field Crops. Total of the eleven combinations of cicer milkvetch, crested wheatgrass and intermediate wheatgrass made up the mixtures as at the ratios of 20, 40, 60, 80 % and pure stand for each species. The seedling numbers of the species among the mixture combinations were significantly different Crested wheatgrass had the highest seedling number as 96.75 per square metre. The differences of seedling dry matter of the species were not significant In these mixtures, according to number of the plant and dry matter yield the ratio of species within botanical compositions significantly differed from each ivother. The plant height of cicer milkvctch, crested whcatgrass and intermediate wheatgrass were 44.54, 75.51 and 88.77 cm, respectively.

Crested wheatgras grown as a pure stand produced 539.14 kg/da hay, whereas the mixture consisted of 40 % cicer milkvetch + 60 % crested wheatgrass possessed the highest hay yield with 596.52 kg/da. Intermediate wheatgrass in pure stand yielded 612.87 kg/da hay, while in the mixture of 20 % cicer milkvetch + 80 % intermediate wheatgrass produced the greatest hay yield with 631.98 kg/da. Cicer milkvetch, the pure stands of crested wheatgrass and intermediate wheatgrass had the dry matter yields of 116.51, 514.99 and 587.83 kg/da, respectively.

In the mixtures of cicer milkvetch, crested wheatgrass and intermediate wheatgrass, the crude protein contents were 12.22, 5.54 and 6.34 %, respectively.
