Abstract
In order to investigate the effect of irrigation disruption at reproductive stages on grain filling of chickpea cultivars, a split-plot experiment based on randomized complete block design with three replications was conducted in 2010 at the Research Farm of the Faculty of Agriculture, University of Tabriz, Iran. Irrigation treatments (I1, I2, I3 and I4: Well watering and irrigation disruptions at flowering, grain filling and during flowering and grain filling, respectively) and chickpea cultivars (Azad, Jam and ILC482) were allocated to main and subplots, respectively. Water stress during reproductive stages caused reduction in leaf chlorophyll content index. In all of the stages of crop growth and development, leaf chlorophyll content index of ILC482 was higher than that of the other cultivars. Grain filling duration, maximum grain weight, grains per plant and grain yield per unit area were significantly reduced by irrigation disruption during flowering and grain filling (I4). The lowest grain yield of Jam was attributed to the lowest grain filling rate, grain filling duration and maximum grain weight of this cultivar.
