An experiment was conducted to evaluate the potential of plant growth promoting rhizobacteria (PGPR) for enhancing yield and yield contributing characters of MR219 rice variety in limited water environment. A total of 20 bacteria were isolated from different dry rhizosphere soil samples. Nine isolates (A1, A4, A5, B4, C2, C3, D1, D2a and D3) were found to fix nitrogen by changing the colour of malate media into pale blue. Six isolates (A4, B2b, B4, C2, D2a and D4) developed halo zones on phosphate growth medium showing their ability to solubilize phosphate on such media. The significantly highest IAA was produced by the isolate D2a. Based on the results of in vitro screening test, two best performed isolates were further evaluated on rice variety MR219 under drought condition. The results of the glass house study revealed that, both the selected isolates B4 and D2a were effective in enhancing plant physiological and yield contributing characteristics over control treatment indicating their potential to be used as PGPR in rice variety MR219 under drought condition.
