Plant Growth Promoting Rhizobacteria (PGPR) are the plant rhizosphere inhabiting bacteria that can promote plant growth by direct and indirect mechanisms. By considering usefulness of PGPR in sustainable agriculture, isolation and screening of multifaceted PGPR was carried out from banana rhizosphere soil samples. Total 54 isolates were obtained in pure culture from fourteen banana rhizospheric soil samples collected from different locations by considering diverse past cropping pattern. In vitro characterization data revealed that 72.22% showed antagonistic potential; 61.11%, 70.37% and 35.19% were positive for protease, amylase and lipase secretion respectively. In terms of increase in nutrient availability, 37.04%, 38.89%, 35.19% and 16.67% were showing positive phosphate solubilization, potash mobilization, zinc solubilization and nitrogen fixation respectively. Indole-3-acetic acid production was detected in 16.67% isolates and 24.07% were found positive for ACC deaminase activity. Two most potent isolates with multiple plant growth promoting characters were identified as Bacillus subtilis and Enterobacter cloacae. Therefore, exploring such multifaceted isolates in the sustainable way to solve the problems associated with overuse of synthetic chemicals in conventional agriculture. This is a step ahead for healthy food production along with enhancement of nutritional value of food.
