Abstract
A field experiment was conducted to evaluate effect of planting density and variety on the grain yield and yield components of chickpea .The present research was conducted in the Agricultural Research Station, College of Agriculture, Islamic Azad University, Kermanshah Branch, Iran .The factorial experiment was based on complete randomized block design with four replication. In this experiment; the variety in three levels (Jam; ILC-482 and 12-60-31) and the planting density in three level 19; 28 and 57 plant.m-2) were considered. Grain yield; number of pod per plant; number of grain per plant; weight of 100 grain; plant height; distance between 1st pod to soil were significantly affected by variety and density but number of branch per plant and biological yield were affected by density, and harvest index were affected by variety. Results showed that there was also a significant difference (p = 5%) in terms of the interaction of variety × planting density on the number of pod and grain per plant. The maximum photo growing degree day related to 12-60-31 variety and the maximum grain yield related to density of 28 Plant.m-2
