Abstract

The mixing ratio of barley and smooth vetch cv. Maragheh was studied in dryland agricultural research institute station during 2010-2011 growing season. The studied treatments comprised of 100% vetch, 75% vetch+ 25% barley, 50% vetch+ 50% barley and 100% barley. There was different seed densities of vetch including 100, 150, 200, 250, 300 seeds/m² (D_1, D_2, D_3, D_4, D₅). The highest dry matter was obtained from pure barley. The combination of 50% vetch+ 50% barley in the D₂ density produced 17.36 ton/ha fresh forage and 1 ton/ha protein.  The highest land equivalent ratio (1.4) was belonged to 75% vetch+ 25% barley in D₅ seed density. It was concluded that, 50% vetch + 50% barley in D₅ vetch density was the best mixing ratio and seed density regarding both forage quality and quantity in this research.
