Abstract :
    In order to evaluate the effect of biological fertilizers and drought stress on the agrophysiological characteristics of mung bean in Khodaafrin region, a factorial experiment was conducted based on a randomized complete block design with three replications in the 1400-1401 crop year. The first factor included four levels of irrigation (100% of agricultural capacity (optimal irrigation), 80% of agricultural capacity (mild stress), 60% of agricultural capacity (moderate stress) and 40% of agricultural capacity (severe stress). The second factor included biological fertilizers in There were four levels (no inoculation (control), inoculation with mycorrhizal fungi, inoculation with Azotobacter and combined use (Azotobacter + mycorrhiza). The results of the analysis of variance of the studied traits showed that the application of stress on all the evaluated traits at the probability level of 1% was significant. The effect of using biological fertilizers on soluble carbohydrates, relative water content was significant at the five percent probability level and other traits were significant at the one percent probability level. The results of variance analysis showed that the interaction of drought stress and biological fertilizers on plant height at the level The probability of a significant percentage and had no significant effect on other traits.
