The negative effects of water stress, reduced water use and nutritional disorders in plants. So in order to study the effects of foliar application of iron and manganese on some morphological and physiological characteristics of Mungbean (cultivar beam) under water deficit stress, this experiment was conducted in the Faculty of Agriculture of Tarbiat Modares University as randomized complete block design arrangement in split plot with three replications. Treatment of water difficit stress, is irrigation regims in three levels: [optimal irrigation, withholding irrigation from vegetative growth (stage of Primary growth to the fast formation of leaves) and withholding irrigation from flowering stage to the first pod formation stage] As main plot and and foliar application of micronutrients included were (no foliar application, water foliar application, iron sulfate 1%, iron sulfate 1.5%, manganese sulfate 0.5%, manganese sulfate 1%, iron sulfate 1%+ manganese sulfate 0.5% and iron sulfate 1.5%+ manganese sulfate 1%) Were considered as sub plot. The results showed that foliar application of iron and manganese could prevent the devastating effects of drought stress And the effect of combined treatment of iron and manganese were higher than other treatments of foliar application. Foliar application of 1.5% Fe+ 1% Mn Reduced proline content in the vegetative and reproductive stress conditions, respectively 62 and 64 percent and total chlorophyll content in the vegetative and reproductive stage increased  respectively 43.5 and 45.8 percent.
