In recent years due to drought yield of crop is adversely affected. In this context to increase the crop yield by utilising drought prone region, influences of moisture stress tolerant rhizobacteria on growth parameter of sorghum plant were examined under moisture stress conditions. Four autochthonous moisture stress tolerant bacterial strain isolated from semiarid region identified as Serratia marcescens strain L1SC8, Pseudomonas putida strain L3SC1, Enterobacter cloacae strain L1CcC1 and Serratia marcescens strain L2FmA4. Sorghum bicolor crops inoculated these bacterial isolates were subjected to moisture stress conditions. These isolates showed enhanced 1-aminocyclopropane-1-carboxylic acid deaminase and IAA production. The enhanced ACC deaminase activity can helps plants to lower the deleterious effect of excess ethylene. Seed priming of these bacterial isolates enhanced germination%, functional leaves, height and yield of Sorghum bicolor significantly over control under drought conditions. Hence it can be conclude that these bacterial cultures can be potentially use as PGPR as well as drought stress mitigating cultures to mitigate deleterious effect of drought stress in Sorghum bicolor crops in arid and semi-arid areas.
