Interaction of Glomus fasciculatum, Rhizobium and Meloidogyne incognita on black gram Cv. T-9

The plants inoculated with Rhizobium + VAM and VAM alone significantly increased plant growth characters and number of nodules over the plants inoculated with nematode alone. All the treatments, except with Rhizobium + nematode in respect of pod yield were found to be effective in increasing plant growth parameters, number of nodules, number of pod. Rhizobium + VAM + nematode and Rhizobium + nematode combination were found to be effective in reducing galls, egg masses on the roots of black gram and nematode population in soil over the plants inoculated with nematode alone. Rhizobium + VAM combination showed highest mycorrhizal colonization percentage and VAM spore population followed by the plants inoculated with VAM alone.
