In order to evaluate the possibility of the balangu intercropping with chickpea in the rainfed condition at Mashhad during 2015-16. A factorial experiment was conducted in the randomized completed block design with three replications at the research farm of Ferdowsi University of Mashhad. Treatments were included plant ratio of balangu / chickpea (0:100, 100:100, 75:100, 50:100, 25:100, 100:0) and weeding time (50 and 70 days after planting). Results showed that the weeding time had significantly (p≤ 0.1) increased the balangu dry matter and seed yield. Weeding, 70 days after planting increased 10 and 24.5 percent of dry matter and seed yield respectively.By increasing balangu plant ratio, biomass and seed yield significantly increased. According to the results, planting ratioes (100:50 , 100:75) can be useful and economic so that had the most (LER) was obtained at those planting ratioes.
