The importance of plant growth promoting rhizobacteria in growth promotion and their ability to elicit
‘induced systemic tolerance’ against abiotic stresses has been documented. However, the performance
of these microbes under various abiotic stresses especially saline-sodic conditions will be of great
importance in the current agricultural scenario. In this study, we isolated 16 rhizobacteria through
natural selection from saline sodic soils, and characterized them using morphological and biochemical
parameters. These bacteria were assessed for their plant growth-promoting rhizobacteria (PGPR) traits
like indole-3-acetic acid (IAA) production, ammonia and hydrogen cyanide (HCN) production, phosphate
solubilization, etc. Furthermore, they were screened for in-vitro salt (NaCl) tolerance and Na+
uptake
pattern, where two stress tolerant rhizobacteria B-1 and B-3 identified as Bacillus pumilus and Bacillus
subtilis showed all PGPR traits with tolerance to salinity. These isolates also elicited significantly
higher vigor index in tomato seedlings grown in pot culture experiments under saline sodic soils of pH
9.35 and EC 4.2.
