Cultivation and development of suitable fodder crops under rainfed conditions is important in order to provide a part of the fodder needs of the country and to create a suitable cultivation pattern in the rainfed lands. In order to, pure cultivation of vetch, bitter vetch, fodder pea and grass pea, and mixed cultivation of these crops with barley plant was compared in a randomized complete block design with three replications at the Sarab-Chengai research station. Mixed cultivation of fodder pea+ barley and pure cultivation of fodder pea and mixed cultivation of bitter vetch+ barley had the highest of dry forage yield with mean yield of 9731, 9282 and 7194 kg/ha, respectively. Mixed cultivation of forage pea+ barley, pure cultivation of forage pea and mixed cultivation of bitter vetch+ barley were ranked first to third with precipitation productivity of 3.24, 3.1 and 2.4 kg/m3, respectively. The mixed cultivation of forage pea+ barley, pure cultivation of forage pea and mixed cultivation of bitter vetch+ barley with net profit and benefit-cost ratio (702785 thousand rials/ha and 3.58), (646410 thousand rials/ha and 3/29) and (485,721 thousand rials per hectare and 3/07) were ranked first to third, respectively. Based on the results of obtained, the mixed cultivation of forage pea+ barley is recommended as the best treatment in areas with similar climate in experimental site due to the higher dry fodder yield, and higher values of precipitation productivity, as well as the economic advantage compared to other treatments
