| Abstract: | Three species of AM fungi, Glomus mosseae, Glomus microcarpum, Gigaspora margarita and a fungus that mimics the properties of AM fungi, Piriformospora indica, were tested on green gram Phaseolus aureus Roxb. (= Vigna radiata var. radiata)] individually and in combination with Rhizobium for their influence on growth and seed yield. The growth parameters analyzed were dry biomass, total leaf area, total chlorophyll,% root colonization, nodulation, and nitrogen, phosphorus, and potassium (NPK) content of leaf tissues using standard methodologies. Glomus microcarpum was found to be more effective in promoting biomass and seed yield when applied alone. But in combination with Rhizobium, G. mosseae enabled highest production of biomass. The tissue nitrogen content was high in G. microcarpum—Rhizobium dual inoculated plants. Many other characteristics were high in dual inoculation, while tissue P was high in individual treatment of G. mosseae. Piriformospora indica was not found to be a good synergist on green gram. |
