Response of peanut to rhizobia depended on indigenous rhizobial populations and their effectiveness. The aim of this study was to identify the indigenous peanut rhizobia and their effectiveness variations in relation to cropping system. Indigenous rhizobia were present in a high number in an area where peanut was cultivated continuously and in cultivated areas having legume rotated or in fallow where native legumes are present. The low populations were found mainly in cultivated areas continuously planted to other crops rather than legumes. There was no relationship between the variation in effectiveness and cropping system.
