Azotobacter in soil supplemented with 1 % glucose. Soil was kept at Held capacity moisture level (16%) and inoculated with Azotobacter strains (Al, A2. A3. A4. A5 and A6) at room temperature for 150 days. All the strains increased the nitrogen content of soil significantly as compared to control. Linear increase in soil nitrogen content was observed upto 90 days incubation and after that a slight decrease was noted. Strain A4 showed the higher activities and fixed 144 Kg N ha which was 12.03% higher than control (after 90 days incubation). Keywords: Nitrogen fixation, Azotobacter, Inoculation, Incubation.
