Author(s): Devendra Kumar Kurrey, Mahendra Kumar Lahre and Gaurav S Pagire
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, T3:99g/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).
