Effect of cultivar and sowing date on grain yield and quantitative traits in chickpea (Cicer arietinum L.)

This research was done in order to investigation effect of cultivar and sowing date on grain yield and quantitative traits with three chickpea cultivars (Filip-84-48-c, Ilc-482 and Arman) and three sowing date (6Mar, 21Mar and 4 Apr). A 3*3 factorial experiment in RCBD format with three replications was conducted in research field azad university of Kermanshah during 2006. The result showed that by increasing the growing season, plant height, distance of the first pod from earth surface, number of stems per plant, number of pods per plant, number of seed per plant, grain yield and biological yield were increased. The 6 Mar sowing date had the highest and the 4 Apr had the lowest grain yield. There were significant differences between cultivars about grain yield. The highest grain yield belonged to Arman with 1067.1 kg/ha. Results showed that number of seed per plant (r= 0.846**), number of pod per plant (r= 0.827**), plant height (r=0.813**) and biological yield (r= 0.798**) the highest positive correlation with grain yield.
