ABSTRACT
An experiment was carried out to determine the symbiotic effect of mycorrhiza on the yieldand root characteristics of Sorghum vulgare under water stress. The experiment was carried out in afactorial test using a Randomized Complete Block Design (RCBD) in three replications. Treatmentswere conducted base on drought stress in four levels and mycorrhiza were applied in two ranges M1(inoculated by mycorrhiza) and M0 (non-mycorrhiza). The Results showed that, the drought stress hadsignificant influences on dry matter of shoot, length of the root and percentage of the mycorrhizacolonization. It seemed that, the mycorrhiza had significantly increased the biomass of sorghum byinfluences on the root characteristics, such as: root length, colonization and root/shoot ratio.
