title: Nodulation studies in species of genus Cassia.
abstract: An examination of eight species of Cassia for nodulation under natural unsterilized soils of different types from varied agroclimatic regions, as well as under aseptic conditions, inoculated with rhizobia, representing all the 8 cross inoculation groups, showed lack of nodulation in all the tested species. The absence of specific strains of rhizobia and the morpho-physiological features of the non-nodulating species of Cassia were considered the possible non-nodulating causes.
