The present investigation was undertaken to find out efficient strains of arbuscular mycorrhiza (AM fungi) alone or in combinations with Trichoderma viride for inoculation of Dendrocalamus strictus seedlings. The inoculated seedlings showed good response having higher plant height, phosphorous ions concentrations in roots and shoots, AM spore number and root colonization than non-inoculated seedlings in both single and co-inoculation experiments. T. viride showed significant growth followed by Glomus mosseae, G. fasciculatum and mixed AM with single inoculation. In co-inoculation, the best growth responses were observed with G. fasciculatum + T. viride followed by G. mosseae + T. viride, mixed vesicular arbuscular mycorrhizas (VAM) + T. viride, G. mosseae + G. fasciculatum + T. viride + mixed VAM, G. mosseae + G. fasciculatum + T. viride and G. mosseae + G. fasciculatum after 120 days. In addition, maximum increase in P concentrations in shoots and roots was observed when compared with other inoculated seedlings. However, all the inoculated seedlings showed significant increase in P concentration when compared with control seedlings.
