To evaluate effect of different irrigation regimes and mycorrhizal fungi on the growth and grain yield of mungbean (Vigna radiata (L.), a pod experiment was conducted in factorial arrangement based on completely randomized design with three replications at Urmia university in 2009. Treatments were irrigations (after 25, 50, 75 and 100 mm evaporation from class A pan) and mycorrhiza (Glomus mosseae, G. intraradices and a non-inoculated treatment as a control). Results showed that total dry weight, leaf dry weight, leaf area increased by diminuting of irrigation intervals. So, the highest (5.14 g/plant) and lowest (1.97 g/plant) grain yield were observed at 25 and 100 mm evaporation from class A pan, respectively. But, application of fertilizer sources to compensate the undesirable effects of drought stress, so the maximum grain yield (63 %) was obtained from mycorrhizal mungbean plants compared with non mycorrhizal plants due to the highest total dry weight, leaf dry weight and leaf area in symbiosis conditions. Water deficit stress caused to decrease pods/plant (49.82%), grains/plant (20.26%) and grains/pod (60.43%). Mycorrhizal fungi species enhanced grain yeild of mungbean through their effects on pods/plant, grains/plant and grains/pod. In conclusion, these results showed that the mycorrhizal inoculation have compensated the water deficit induced yield (49.61%) losses.
