Abstract

The study was evaluated to assess the effect of co-inoculation with bacteria and arbuscular mycorrhizal (AM) fungi on the growth of sesame (Sesamum indicum L.) varieties. The two varieties of sesame TSES 1 and TSES 4 were inoculated with single, double, and triple inoculations. The results revealed that triple inoculation of Glomus fasciculatum (Gf) + Azotobacter chroococcum (Ac) + Pseudomonas fluorescens (Pf) to TSES 1 and Acaulospora laevis (Al) + Ac + Pf to TSES 4 stimulated increased root colonization, plant growth, plant biomass, phosphorus content, and number of capsules significantly over the double and single inoculation treatments. These results suggest synergistic interaction among arbuscular mycorrhizal (AM) fungi, Azotobacter chroococcum, and Pseudomonas fluorescens. The association of bacteria and AM fungi provide evidence that bacteria are involved in the beneficial effects to AMF on plant growth and can improve crop production.
