The effect of circuit irrigation, mycorrehiza inoculation and zeolite on yield and water use efficiency of mung bean

In order to evaluate the effects of irrigation intervals, mycorrhizal fungi and zeolite fertilizer on some Mung bean traits, a factorial splitting experiment was conducted in a randomized complete block design with four replications in the Izeh region in July 2015-1016. The main factor included irrigation interval at three levels (7, 10 and 13 days) and various factors were Mycorrhiza inoculated (inoculated and non-inoculated) and zeolite (without consumption and 2 tons per hectare) as a factorial.The results of analysis of variance showed that only interaction effect of irrigation, mycorrhiza and zeolite on stem weight, number of seeds per pod and water use efficiency were significant. The highest grain yield was observed in irrigation intervals of seven days under inoculation and non-inoculation with fungus, as well as irrigation intervals of 10 days in inoculated mycorrhizal fungus. The use of zeolite in irrigation intervals of 10 and 13 days increased the most of traits. The results of water use efficiency showed that use of Mycorrhiza fungus and zeolite fertilizer increased water use efficiency. So that, by increasing the irrigation interval from 7 days to 10 days, using mycorrhiza and zeolite can prevent decreasing of water use efficiency. According to the results of this study, using mycorrhiza fungi and zeolite fertilizer can increase the irrigation interval of mung bean from seven to 10 days in the studied area.
