In this study, eleven soil samples were collected from Terai zone of West Bengal. The Azotobacter were isolated by serial dilution method from each sample in specific Azotobacter agar (Mannitol) and incubated at 28±2 °C for 48 hour than kept in refrigerator. The best strains of Azotobacter were evaluated by in-vitro and in-vivo screening. The highest population and nitrogen fixation ability was recorded in rhizosphere soil of Mathura tea garden designated as UBAZ-5 (7.3x109). UBAZ-5 was also found significantly superior in physical characteristics of chilli plant. The shoot length (12.03 cm), root length (14.33 cm), shoot fresh weight (1.26 g) and root fresh weight (0.55 g), shoot dry weight (0.30 g) and root dry weight (0.21 g) of UBAZ-5 bioinoculated chilli plants were found to be superior to un-inoculated check. Hence, use of bioinoculant will increase the physical characteristics and further increases crop productivity.
