Abstract:

A field experiment was conducted to evaluate the effect of Azotobacter isolates collected from rhizospheric soil of fodder grasses viz., Napier grass, Marvel grass, Anjan grass, Stylo grass, Johnson grass, Fodder jowar and Fodder maize as a seven treatments. The morphological, biochemical and cultural characteristics of individual isolate was studied. The nitrogen fixing ability of these seven isolates were carried out in which Azotobacter isolated from Napier grass showed highest nitrogen fixing ability with 19.62 mg /g of sucrose consumed which was followed by Azotobacter isolated from Johnson grass with 18.21 mg/ g of sucrose consumed. The application of lignite based biofertilizer of individual Azotobacter isolates as a seed treatment to the sweet corn seeds showed increased trend in various growth parameters in which the yield of sweet corn obtained due to treatment of Azotobacter isolated from rhizospheric soil of Napier grass found significantly higher (265.87 g/plant) than rest of treatments. Hence, the Azotobacter strain of Napier grass can be commercialized as an efficient biofertilizerstrain of Azotobacter.
