Abstract: 
In order to study the effect of plant density on the forage yield, grain yield and yield components of three barley genotypes in dual-purpose sowing conditions, a field experiment was conducted in 2004-2005 growing season. The experiment was split-plot with RCB design and three replicates. Main plots were three barley genotypes (Jonoob, Tropy and 13 Sarasary) and sub-plots were four plant densities (300, 400, 500 and 600 plats per m2 ). Forage was removed from five cm above the ground at the beginning of the stem elongation phase. Results indicated that the genotype and plant density effect on grain yield was not significant. The interaction effect of the experimental treatments was not significant for grain weight and grain yield, but it was significant for biological yield, number of spike per unit area, number of grain per spike and harvest index traits. The highest grain yield, biological yield, number of spike per unit area and grain weight was in Tropy genotype. The differences among genotypes and genotype._density were not significant for hay (dry forage) and forage (fresh forage) yields. The highest and the lowest hay and forage yields were in 600 and 300 plants per m2 treatments, respectively.
