Cultivars Effect of Row Spacing and Plant Density on Some Morphological Traits, Yield, Yield Components and Seed Protein in Two Chickpea (Cicer arietinum L .) Cultivars 113 126 1527 FA A Yeilagh Cheghakhor M Mesgarbashee R Mamghani M Nabipour Journal Article 2014 06 18 An experiment was conducted to evaluate the effects of row spacing and plant density on some morphological traits, yield, yield components and seed protein in two chickpea cutivars in 2007 -2008 at College of Agriculture, Chamran University of Ahvaz, Iran. The design of experiment was a split plot factorial in a randomized complete block design with three replications. Main plots were devoted to a three row spacing (40 , 50 and 60 cm ), while minor plots assigned to two plant densites (25 and 35 plants per m² ) as well as two cultivars (Arman and Hashem). Results showed that row spacing had no significant effect on all investigated traits. Howevere, number of pods/unit area, seed yield, biological yield and 100 seed weight were relatively smaller in row spacing of 60cm. Plant density had positive significant effect on number of pods/unit area, seed yield and biological yield, so that plant density of 35 plants/m² has greatest yield. The number of branches were also significantly more in density of 25 plants/m². Hashem cultivar had greatest plant height, first pod height and biological yield. So, Arman cultivar had maximum harvest index as compared with Hashem cultivar. Howevere, using combinded treatments of narrow row spacing (40 or 50 cm) and higher plant density (35 plants/m²) produced greatest seed yield in the two cultivars.  An experiment was conducted to evaluate the effects of row spacing and plant density on some morphological traits, yield, yield components and seed protein in two chickpea cutivars in 2007 -2008 at College of Agriculture, Chamran University of Ahvaz, Iran.
