Effect of supplemental irrigation and iron spraying on chickpea genotypes in Kermanshah

In order to investigate the effect of supplementary irrigation and iron spraying on morphological and physiological traits of four chickpea genotypes,including two Kabuli types and two Desi types,an experiment was conducted in field conditions.The cultivation was done at Research Field of Islamic Azad University, Kermanshah branch during 2012-2013 using split plot based on complete randomized block design with four replications. The effect of supplemental irrigation at flowering stage on seed yield and some other traits have positive and significant, as it leads to an increase of 48% and 45%, respectively, in the number of pods per plant, number of seeds per plant and 30 percent seed yield compared to the lack of irrigation.Local genotype Kabuli Bivanij compared with other genotypes increased 60 percent seed yield, the best answer to the supplementary irrigation.the iron spraying led to increase seed yield was small,but significant.In total iron spraying with supplemental irrigation, all genotypes showed a greater impact on yield.
