Abstract:

48 genera 122 species of tree legumes were examined for nodulation in field and seedling nursery. Among them, 82 species were found to be nodulated. 123 strains of root nodule bacteria from nodules of the trees were isolated following the method suggested by Vincent (1970). Isolates of rhizobia were purified and maintained on YEMA slants. Strains of rhizobia obviously differ from one another in characteristics of colonies and growth rate.

Key words: Tree legumes, Root nodule bacteria, Nodulation, Symbiotic nitrogen fixation
