Abstract: Azotobacter is been studied for nitrogen fixation bacteria is soil and effect positively on growth, yield, biochemical properties along with soil quality. Thus present study was carried out to evaluate the response of bio-fertilizer (Azotobacter) in case on onion. Doses (T₀: NPK, T₁:33g/m², T₂:66g/m², T_3:99g/m², T₄:132g/m², T₅: 166g/m², T₆:199 g/m²) were decided on the basis of nitrogen requirement by the onion crop. The results shows significant increase in germination percent T₅(85%), bulb weight T₅(120.7g), maximum diameter of bulb T₅(6.2cm), bulb dry weight T₅(23.9g), plant dry weight T₅(28.2g), harvest index T₅(69.35%) and plant height T₆(57.3cm), No. of leaves T₆(11.4), chlorophyll- a T₆(0.86mg/g FW), chlorophyll b(0.47 mg/g FW) and carotenoid(0.75 mg/g FW), leaves protein T₆(0.45 mg/g), bulb protein T₆(1.2 mg/g), bulb sulphur T₆(5.64 mg/g).
