Abstract

The present investigation was undertaken to study the synergistic effect of recommended Mesorhizobium sp. (LGR -33) (Meso) and native potential PGPR Pseudomonas sp. (PGPR 2 and PGPR 3) along with reference strain Pseudomonas diminuta (LK884) on bio-enhancing activity, symbiotic parameters and grain yield in desi (PBG 1) and kabuli (BG 1053) under field conditions in chickpea during rabi 2009-2010. Significant improvement in growth and symbiotic parameters was observed with co-inoculation of Mesorhizobium sp. with native potential Pseudomonas sp. PGPR as compared to single inoculants of Mesorhizobium sp. in both varieties. Maximum improvement in symbiotic parameters was observed with co-inoculation of Mesorhizobium sp. and PGPR 3 followed by native PGPR 2 as compared to LK884 (reference). On an average, co-inoculation of Mesorhizobium sp. with PGPR 3 improved the yield by 7.0% (desi) and 5.3% (kabuli) over Mesorhizobium sp. alone. It appears that native potential Pseudomonas sp. PGPR can be explored as potent bio-enhancers and bio-fertilizers along with Mesorhizobium sp. in chickpea under low input technology programme of sustainable agriculture
