ABSTRACT
A pot experiment was performed to see the effect of co-inoculation of endomycorrhizal fungi with other beneficial microbes on establishment and growth of E. saligna seedlings. The dominant VAM fungi i.e. Glomus mosseae, Glomus fasciculatum and mixed VAM consortium (species of Glomus, Acaulospora, Sclerocystis and Gigaspora) along with Trichoderma viride were isolated from the rhizosphere soil of Eucalyptus saligna and mass produced in laboratory for further studies. Double inoculation of mixed VAM + Rhizobium sp. showed maximum increase in seedling height over other treatments and control. Glomus mosseae + Rhizobium sp. showed more root P content than other treatments, where as shoot P content was more in mixed VAM + Rhizobium sp. and G. mosseae + Rhizobium sp. inoculated seedlings. Triple inoculation also exhibited significant positive response on growth of E. saligna seedlings. Mixed VAM + Rhizobium sp. + Trichoderma viride had more increase in height, VAM spore number and percentage mycorrhizal root colonization than other treatments and control. G. mosseae + Trichoderma viride + Rhizobium sp. treatment showed more root P content over other treatments while shoot P content was also more in G. mosseae + Rhizobium sp. + Trichoderma viride followed by mixed VAM + Rhizobium sp. + Trichoderma viride treatment. However, P content of shoot and root in all double and triple inoculations was more over control. Dual and triple inoculation (co-inoculation) of microbes (bioagents) has beneficial effects on plant growth and development. Although, dual inoculation had good response but triple inoculation had more pronounced and significant response on growth and development of this plant.
