Earthen pot experiments were conducted in a randomized block design with three replications to evaluate the effects of sesame varieties, DS 1 and E 8 on a single inoculation of Glomus fasciculatum (Thax. sensu Gerd.) Gerd. and Trappe and Acaulospora laevis Gerd. & Trappe respectively, dual inoculation of arbuscular mycorrhizal fungi (AMF) with Azotobacter chroococcum (Ac) or Pseudomonas fluorescens (Pf) and a triple inoculation of AMF, A. chroococcum and P. fluorescens. The results revealed that inoculation of AMF + Ac + Pf to DS 1 and E 8 varieties stimulated increased AMF colonization, plant growth, i.e. shoot, root length, fresh and dry weight of shoot and root, phosphorus uptake and number of capsules significantly over the dual and single inoculation treatments. The association of bacteria and AMF provides evidence that bacteria are involved in the beneficial effects to AMF on sesame varieties.
