摘要：Chickpea is a major food crop and the world＇s third most widely-grown legume after bean （phaseolus vulgaris L.） and pea （pisum sativam L.）. The yield of chickpea can be improved by planting of optimum density of chickpea cultivars. The purpose of this research was to investigate the effect of plant density on yield and some characteristics of chickpea （Cicer arietinum L. var. Philips）. A field experiment was conducted on research farm of, Gonbad High Education Center, Iran. The study was laid out factorial in randomized block design with four replications. The treatments were factorial row spacing （A1=35 cm, A2=45 cm and A3=55 cm） and plant spacing in the row （Plant-within-spacing row） （B1=5 cm, B2=7.5 cm and B3=10 cm）. AIBI=（35×5）=57.14, AIB2= （35×7.5）=38.09, A1B3=（35×10）=28.57, A2B1=（45×7）=44.44, A2B2=（45×7.5）=29.26, A2B3=（45× 10）=22.23, A3B1=（55×5）=36.36, A3B2=（55 ×.5）=24.24, A3B3=（55 × 10）=18.18 plant.m^-2. At the harvest time, 5 plants of each plot were selected randomly and used for determination of pods per plant, unfilled pod per plant, height and number of branches. Result showed the yield was not affected by density. The maximum yield obtained in row spacing 55 cm and plant spacing in the row 7.5 cm which was equal 1802.87 kg·ha^-1. Row spacing had statistically significant effect on the pod number per plant, branches number per plant and plant height.
