Biological fertilizers are natural inputs that can be used as complementary or alternative fertilizers in sustainable agriculture. A split plot experiment has been conducted in a randomized complete block design with three replications in Khuzestan province during 2018-19. Three different planting methods (spraying), linear and atmospheric and stack plots in main plots and three levels of application of 100% urea, 70% urea plus 100 g Azotobacter, 50% urea plus 100 g Azotobacter in plots. Sub-comparisons. The results of analysis of variance showed that the main effects application of urea fertilizer plus azotobacter and planting pattern had a significant effect on number of pods per plant, number of seeds per pod, grain yield, protein percentage, parietin yield. The use of 70% urea plus Azotobacter significantly increased the yield of rapeseed oil but was in a class with 100% urea treatment. The use of 70% urea plus Azotobacter significantly increased the yield of rapeseed oil but was in a class with 100% urea treatment. Interaction between sowing pattern and the combination of urea and aztobacter had a significant effect on grain yield and biological yield. The most appropriate yield of method planting furrow and 70% of urea with azotobacter application. In this study, considering the 25% savings in nitrogen fertilizer consumption, in addition to 33% increase in canola quality, it reduced the costs by 30%, which is economically viable and recommended.

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.
