EFFECTS OF INOCULATION WITH GLOMUS-MOSSEAE, AZORHIZOBIUM-CAULINODANS AND ROCK PHOSPHATE ON THE GROWTH OF AND NITROGEN AND PHOSPHORUS ACCUMULATION IN SESBANIA-ROSTRATA

A study was carried out to evaluate the influence of single or dual in oculation with Glomus mosseae and Azorhizobium caulinodans with and wi thout rock phosphate on the growth of and N, P and K accumulation in S esbania rostrata grown in sterilized soil. Height of plants inoculated with G. mosseae in combination with A. caulinadans and/or rock phosph ate was significantly higher than that of uninoculated plants or plant s inoculated with A. caulinodans alone before but not after 28 days. H owever, the oven-dry weight of shoots and roots from all treatments di d not vary significantly. Generally, concentration and uptake of N and P but not K in shoots and roots of plants were improved by dual inocu lation with G. mosseae and A. caulinodans plus or minus P. Mycorrhizal infection of roots was enhanced significantly by A. caulinodans.
