Indigenous And Introduced Arbuscular Mycorrhzae (Am) And Rhizobium On Growth, Nodulation And Physiology Of Albizzia Lebbeck Benth. In Red Lateritic Soil

Albizia lebbeck Benth. is used for afforestation in dry nutrient poor area, in agro-forestry as shade tree for tea and coffee. Dry nutrient poor soils constrain the growth of the plant. Interaction between Rhizobium and two AM fungi, isolated Glomus aggregatum from lateritic soil and introduced G. mosseae and their symbiotic effect on growth and nutrition of Albizia lebbeck seedlings were studied. Rhizobium enhanced root and shoot growth, shoot Nitrogen and soluble sugar content more than AM fungi while other parameters were enhanced by AMF. Dual interaction of Rhizobium and AMF enhanced all parameters over single inoculations except soluble sugar content and root shoot ratio.
