azotobacter as biofertilizer

The commercial history of biofertilizer start with the introduction of “Nitragin” by Nobbe and Hiltner, a laboratory culture of Rhizobia in 1895, followed by discovery of Azotobacter and then blue green algae (Ghosh, 2004; Mazid et al., 2011; Mazid and Khan, 2015; Das et al., 2015). Azotobacter is a biofertilizer which provides the required amount of nitrogen to the plant from the soil.  |  Azotobacter biofertilizer. The highest weight gain and specific growth rate recorded in Azotobacter treated fish may be attributed to the highest NPP, NO 3 and PO 4 recorded in that treatment.
