In order to evaluate the effects of foliar application of methanol and irrigation intervals on yield and yield components of chickpea cultivars a factorial experiment as split plots based on randomized complete block design with three replications was conducted in spring 2008 at the Agricultural Research Station of Ferdowsi University of Mashhad. The treatments were 10 and 20 irrigation intervals as main plots and factorial combination of cultivars, ILC482 (Kabuli type) and Piroz (Desi type) with concentration of methanol 0, 10, 20 and 30 volume percent as subplots. Methanol sprayed on chickpea shoots after podding with 10 days interval. The results showed the effects of foliar application of methanol on yield and yield components were significant. Spray of 30 percent concentration affected yield and yield components more than other treatments. So that it increased number of pods, 100 seed weight, seed weight, seed number per plant and harvest index. Biological yield was the highest (2198 kg/ha) for 30 percent methanol and the lowest for zero percent (1823 kg/ha). In addition, 30 percent methanol had the highest grain yield (1243 kg/ha) and the lowest (904 kg/ha) was related to zero percent methanol. According to the results, foliar application of 30 percent methanol could be recommended for increasing the yield of chickpea.
