In order to study the responses of grain yield of chickpea to drought stress and application methods of nitrogen fertilizer, an experiment carried out as split-plot at Campus of Agriculture and Natural Resources, Razi University, Kermanshah, Iran, during 2009-10 and 2010-11. The supplementary irrigation at three levels (1. without irrigation, 2. one irrigation at flowering, 3. two irrigations at flowering and podding stages) as main-plot and the combination of different amounts and application methods of nitrogen fertilizer were as sub-plots. The results showed that grain yield was increased significantly due to increasing of the number of grains per plant and 100-grain weight in response to supplementary irrigation treatments. There was no significant difference in grain yield between one and two supplementary irrigation treatments with 1646 and 1728 kg/ha, respectively. Methods of nitrogen application had significant effects on grain yield and some yield components, but had not effect of 100-grain weight. Foliar spraying accompanied by soil application of N increased significantly grain yield. Finally, to get high grain yield in chickpea we recommend supplementary irrigation at flowering stage and also usage of both nitrogen application methods (soil application + foliar spraying).
