Abstract
Soil salinity has emerged as a serious issue for global food security. Salt tolerant bacteria were isolated from paddy filed and its efficiency on salt stress were evaluated by in situ method. The conventional methods were used to isolate and characterization of bacteria. Ability of isolate thrives in extremely salt concentrations is first evaluated in this study. Isolate positive sp showed positive response on salt tolerance, siderophore production, phosphate solubilisation and chromium reduction. Seed germination results confirmed the beneficial effects of Bacillus sp and Rhizobium sp individually with lowest vigour index. Plant growth promoting efficiency among dual culture showed significant results in root length, shoot length and germination rate, when compared to uninoculation, co inoculation showed significant seed germination index. The present research concludes co culturing of strain Bacillus sp with Rhizobium sp has the highest capability for stimulating plant under 3% of salt stress. PGPR mediated mechanisms of salt tolerance in tested plant and future research trends of using ST-PGPR for reclamation of saline soils.
