In order to investigate the effect of magnetized water on improvement of drought tolerance of mung bean (cv. Partow) a pot experiment was done in Yadegar-e-Imam Khomeini Branch, Islamic Azad University at 2013. This experiment was conducted in factorial at the basis of completely randomized design with four replications. The first factor consisted of two irrigation levels including irrigation after 50 mm evaporation from class A evaporation pan as control and irrigation after 100 mm evaporation from class A evaporation pan as drought stress. The second factor consisted of two types of water including tap water and magnetized water. Results showed that drought stress decreased pod number, seed per pod, 1000-seeds weight, seed yield, biomass and harvest index. Nonetheless, magnetic irrigation increased all measured traits under normal anddrought conditions. Under normal conditions seed yield was recorded 6.81 and 9.70 g plant-1 at tap water and magnetized water treatments respectively. Under drought stress conditions also seed yield was achieved 2.56 and 4.55 g plant-1 at tap water and magnetized water treatments respectively. Therefore, it suggest that irrigation with magnetized water as simple, safe and applicable method can use for improvement growth and yield of mung bean under both normal and drought conditions
