To evaluate the intercropping of annual medic (Medicago scutellata cv. Robinson) and barley (Hordeum vulgare cv. Valfajer) effects on quantity and quality of forage yield production, two simultaneous field experiments were conducted in Khoramabad and Kangavar cities in Kermanshah province during 1382-83 growing season at dry farming system. The intercropping treatments comprised of: sole medic (100% medic), 100% medic + 50% barley, 100% medic + 75% barley, 100% medic + 100% barley, 75% medic + 50% barley, 75% medic + 75% barley, 75% medic + 100% barley, 50% medic + 50% barley, 50% medic + 75% barley, 50% medic + 100% barley and sole barley (100% barley). Annual medic and barely were sown at 20 and 140 kg pure living seed per hectare in intercropping system, respectively. The first forage harvest was carried out at early flowering stage of annual medic for both medic and barley above the third growing node of the medic plant. The regrowth was harvested from the soil surface. The compound analysis of the data from two experimental sites showed that intercropping of 100% medic and 100% barley and 75% medic and 100% barley produced the highest yield (1906.8 and 1870.8 kg DM/ha, respectively) and protein (319.1 and 269.7 kg/ha, respectively) among all the cropping combinations. Intercropping system of annual medic and barley was more successful in quantity and quality of forage produced in Khoramabad compared to Kangavar because of more suitable climatic conditions.
