In the present investigation total 167 non rhizobial endophytic bacterial isolates from roots of chickpea were collected and screened for qualitative P solubilization. Out of these 37 potential bacterial endophytic isolates from root were selected for further quantitative P-solubilization, Indole acetic acid (IAA), Gibberelic acid and ACC deaminase production. High P-solubilization was recorded in isolate RBR20 (20.60 mg100ml1). Maximum amount of IAA was produced by isolate LCRE 9 (39.60 μgml-1) (presence of tryptophan) and RBR164 (19.93 μgml-1) (absence of tryptophan). High amount of GA production was observed in RBR19, RBR127, RBR136 and RBR164 (112.15 μgml-1). RBR164 isolate showed highest growth in DF medium with ACC (0.9985). There is need to exploit non rhizobial endophytic bacteria with plant growth promoting traits (PGP) as single or consortium biofertilizer for sustainable agriculture.
