Abstract

In order to investigate the effect of drought stress and inoculation with mycorrhizal fungi and rhizobium bacteria on quality and quantity of soybean yield, an experiment has been conducted as a split-plot factorial in a RCBD with three replications at research farm of Agricultural Highschool of Urmia during 2017 cropping season. The main plot has been drought stress, including optimum irrigation, and moderate and severe drought stress, while the sub plots include mycorrhizal fungi in three levels (without mycorrhiza and inoculation with Glomus mosseae and G. intraradices) as well as Rhizobium japonicum in two levels (without inoculation and inoculation with R. japonicum). In response to moderate drought stress, protein percentage has increased, though raising the severity of drought stress reduces protein and oil percentage. Irrigation along with inoculation with mycorhizal fungi, especially G. mosseae, enhances the number of seeds per plant, protein percentage, and protein yield. Under three irrigation conditions, inoculation with bacteria, in comparison with non-inoculation, boosts seed, oil, and protein yield, with inoculation with bacteria and mycorhizal fungi increasing seed and oil yield. Study of correlation coefficient shows that there is a positive and significant correlation between seed yield with 1000-seed weight, number of seeds per plant, and oil and protein yield. According to the results of this research, using mycorrhiza G. mosseae and inoculation with R. japonicum can have a positive effect on the quantitative and qualitative traits of soybeans.
