Problem statement: In order to evaluate drought stress and methanol on yield and yield components of soybean in field experiments with factorial experiment inform of a randomized complete block design with three replication in field faculty of agricultural of Islamic Azad University Karaj, at 2008. First factor were sprayed aqueous solutions 0 (control), 7, 14.21, 28 and 35% (v/v) methanol by 3 times during growth season of soybean with 12 days intervals on shoot of soybean. Second factor were drought stress condition in two levels 40 and 70% base of depletion available soil moisture. Approach: This study measured grain yield, biomass HI, 1000 grain weigh, high plants, number of branch, diameter of stem, number of pod on plant, number of hollow pod. Results: Results of the experiment indicated that significant differences exist (p>0.05) between sprayed of solution methanol on parameters. Results also showed that was significant (p>0.05) differences between effect of drought stress levels on measured parameters. Effect of aqueous solution 14, 21 and 28% (v/v) methanol on measured parameters was greater than other treatments. Foliar application of 14 and 21% (v/v) methanol increased leaf area index, crop growth rate, pod growth rate, leaf area duration, pod yield, seed yield, weight of 1000 kernel, mature pods per plants. Conclusion: The lowest grain yield obtained in control and 35% (v/v) methanol treatments. Interaction effects were not significant.
