ABSTRACT

Azotobacter is free living, diazotrophic bacteria found in soil, which fixes atmospheric nitrogen non-symbiotically. Isolation, characterization of Azotobacter from drought area and testing its ability to fix atmospheric nitrogen can be helpful to use it as a biofertilizer in such area. Thus we can enhance the crop yield in these area. Nitrogen fixing ability of isolates is studied using different nutrients like, carbon source, molybdenum, ferrous and at various temperature, pH. NFA of the isolate can be enhanced by adding the nutrients at specific conc.
