The objective of this study was to characterize the rhizobial isolates obtained from root nodules of Arachis hypogaea plants and to investigate their tolerance efficiency towards salt and Carbaryl insecticide based on growth response analysis. The isolates were then tested for IAA, EPS and HCN production. Eight isolates viz., S1, S2, S3…S8 were found to be tolerant to high concentrations of salt and insecticide. Growth response analysis studies indicated that the tolerance ability of the organisms varied. Of all the strains,   S5 showed high salt and pesticide tolerance and produced substantial amounts of growth factors. Therefore, S5 bacteria may be beneficial to improve growth and development of leguminous plants. Further studies are needed to characterize the strains on molecular basis and to substantiate the results through pot and field cultivational studies under stress conditions.

Keywords: Rhizobium, Carbaryl, Salt, Growth Factors, IAA, EPS, HCN.
