The Fluorescent Pseudomonads were isolated from rhizosphere of fifteen different crops and screened based on their antagonistic effect and effect of metabolites against Jute stem rot pathogen. The five selected isolates were used for seed bacterization to study their effect on seed germination, root length, shoot length and vigour index. The treatment with UBPF20 resulted in 42.41% increase in root length over control followed by UBPF14 (36.22%) and UBPF24 (23.83%). Regarding shoot length all the isolates showed increase in length over control. The isolate UBPF24 increased 47.57% shoot length over control followed by UBPF20 (27.35%).The highest vigour index was found with the treatment of UBPF24 (20.96%) over control followed by UBPF20 (20.18%) and UBPF14 (19.38%). Better plant growth was observed in the plants treated with the selected isolates as compared to control. Jute seed treatment with five selected Fluorescent Pseudomonads isolates induced the plant to synthesize defense related enzymes like Phenylalanine Ammonia Lyase (PAL), Poly Phenol Oxidase (PPO) and Peroxidase (PO). The maximum increase in activity of PAL was found in UBPF14 followed by UBPF24 and UBPF18. The isolate UBPF18 showed highest activity of PPO followed by UBPF24, UBPF22 and UBPF14. The activity of PO was also found higher in all the plants treated with isolates than control.
