Abstract

An experiment was conducted to evaluate the effects of single inoculation of cowpea Bradyrhizobium (RA-5) and dual inoculation of Cowpea Bradyrhizobium (RA-5) and PGPR Burkholderia cepacia (RRE-5) on growth parameters of pigeonpea under various salt concentrations at different time intervals. Results indicated that growth parameters of the dual inoculated plants were significant and more desirable over the respective single inoculated ones. Increased salt concentrations impose undesirable effects on the growth parameters. Best growth was observed in treatment containing dual inoculation of RA-5 + RRE-5 with no salt. Very poor growth was observed in single inoculated plants applied with 200 mM saline solution. Dual inoculated plants significantly reduced the accumulation of sodium (Na+) in their leaves than the respective single inoculated plants.
