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.

Keywords
