Abstract

Arbuscular mycorrhizal fungi constitute one of the important components of soil microbiota, and their inoculation directly involved in improving plant growth under the reduced fertilizer input. Green house experiments were undertaken in Bauhinia varigata L. plant seedlings were grown in phosphorus deficient sandy loam soil with single, double and triple inoculation with three AM fungi. Single and double inoculation steadily improved plant biomass production and phosphorus content in shoot and ischolar_mains. However, triple inoculation significantly improved plant growth, biomass production, and phosphorus content in shoot and ischolar_main, percent ischolar_main colonization and spore number compared to non-inoculated (control) plants. It may be concluded that triple inoculation of AM fungi for Bauhinia varigata at nursery stage considered to be good before transplantation in reforestation programmes.

Abstract

Indigenous arbuscular mycorrhizal (AM) fungus was isolated from rhizosphere soils of Pongamia pinnata. Young seedlings of P. pinnata inoculated with indigenous AMF Glomous fasciculatum showed significant growth and the plants introduced with Glomous mosseae did not show significant effect on growth. The dual inoculation with indigenous Glomous fasciculatum and introduced Glmous mosseae depicted growth response was much greater than the single inoculation. The tripartite system of indigenous and introduced VAM with Rhizobium phaseoli improved significant increase plant height, plant dry matter, nodulation number, N and P content of Pongamia pinnata over non-inoculated plants with either AMF or Rhizobium alone.
