Abstract:

Stress tolerant Plant growth-promoting rhizobacteria (PGPR) are the rhizosphere bacteria that can enhance plant growth under stress condition. In our present study, 32 stress tolerant PGPR strains (8 Rhizobium. 8 Pseudomonas, 8 KRB, 8ZSB) were isolated from the rhizosphere soils of blackgram crop and screened for their ACC deaminase and Exopolysaccharide (EPS) production. Out of 32 isolates four isolates (1 Rhizobium. 1 Pseudomonas, 1 KRB, 1 ZSB) were selected on the basis of their ACC deaminase activity and Exopolysaccharide production. A pot experiment was conducted by inoculating these four isolates with blackgram crop. Four different moisture levels (20%, 40%, 60%, 80%) were maintained to create stress condition. The results revealed that the pot containing combined inoculants of bacteria with ACC deaminase and EPS gives highest yield compared to control during stress condition.
