Abstract :

In order to study the effect of supplementary irrigation on yield, yield components and protein percentages of three cultivars of chickpea an experiment carried out as split plot, based on randomized complete blocks design, with three replications in Ilam, in 2009-2010 growing season. Irrigation treatments were: control, without irrigation (I0), irrigation at the stage of %50 blooming, irrigation at the stage of %50 flowering, irrigation at the stage of pods filling, which were allocated to main plots and genotypes, ILC482, Filip93-93 and local variety to sub plots. Irrigation treatments had significantly effect on seed and biological yields, harvest index, pod numbers per plant, seed numbers per pod and 100 seed weight. The Filip93-93 produced highest (1140.51 kg/ha) and the local variety lowest seed yields (1056.98 kg/ha).Irrigation at the stage of pod filling and blooming increased by seed yield %41.3 and %29.3 respectively as  compared to control .Irrigation at the pod filling period produced the highest seed yield. The Filip93-93 produced highest yield (1263.31 kg/ha) when the field irrigated at pod filling stage and the local variety at control treatment (without irrigation) the lowest seed yield (893.26 kg/ha).
