In order to study the effect of intercropping and sole cropping of barley (Abidar cultivar) with broad leaf vetch (Line 2561) under conditions of used compost on yield of dry forage and utility indices, this experiment in cropping years 2014-15 and 2015-16 was conducted with four levels of compost (control, 20, 40 and 60 ton.ha-1) and five levels of complementary components of intercropping, 100:0 (sole cropping of broad leaf vetch), 40:100 (broad leaf vetch: barley), 70:100, 100:100 and 0:100 (sole cropping of barley) in additive series intercropping in dry land conditions of khorramabad in the college of Agriculture of Lorestan University in the form of factorial in RCBD with three replicates. Results showed that biomass produced in the interaction control×100:40 (broad leaf vetch: barley) in the first and second years, was equal to 5.03 and 5.28 ton.ha-1 and the second year was 4.77 percent lead. The results showed that by increasing the use of compost (40 and 60 ton.ha-1) and broad leaf vetch seed ratio (100: 100), Total Land Equivalent Ratio (TLER) to 2 and even more than it does the desire, Area Time Land Equivalent Ratio (ATER), in all interactions of year×compost×intercropping, was more than 1 (ATER> 1). The max of Land Use Efficiency (LUE) of barley was obtained in the seed ratio of 100:100 and at all levels of the compost and the lowest The E in the first and second year was belonged to the interaction of control×40:100 that was equal to 1.25 and 1.26, respectively.
