dc.description.abstractThirty four rhizobacterial isolates were isolated from mungbean rhizosphere soil collected from different locations of the Punjab. The isolates were evaluated for their PGP traits at 35°Cand 40°C but, it was found that rhizobacteria were more acclimatized to 35°C as compared to 40°C. All the isolates showed IAA production at 35°C (0.13- 56.44μg/ml) and (0.22-36.80μg/ml) at 40°C. The isolates were effective P and Zn solubilizers with P-solubilisation index ranging from 6.9-15.5 at 35°C and from 5-13.8 at 40°C. Zn solubilisation index ranging from 3.8-24.0 at 35°C and 4.6-15.3 at 40°C, most potent isolates being G-2, G-3, G-33 and G-34. Isolates G-2, G-3, G-33 and G-34 were HCN and ammonia producers as well. The biocidal impact of the rhizobacterial isolates against F.oxysporum and R.solani was studied and eight isolates showed antagonistic activity against F. oxysporum and R. solani. Isolates G-2, G-3, G-33 and G-34 proved to be strong antagonistics with 27.0-37.5% inhibition of the phytopathogens. The field experiment conducted revealed that co-inoculation of Rhizobium and G-33 proved to be the most beneficial, resulting in the improvement of symbiotic traits viz nodule number per plant (66.6), nodule dry weight (22.2 mg/plant), root (0.29g/plant) and shoot (11.84g/plant) dry weight and the yield (1134 kg/ha) of mung bean (ML2056) as compared to Rhizobium treatment alone (1093 kg/ha).en_US
