A survey of Azotobacter population was done form the rhizosphere and soil of 15 crop plants during different seasons. In the present study morphological and physiological characteristics of 20 Azotobacter isolates were studied. On the basis of different characteristics five species were identified such as , Azotobacter chroococcum, A.paspali, A. insignis, A.vinelandi and A.beijerinkii. This was based upon the Bergey’s Manual of Systematic Bacteriology (Krieg and Terrand, 1978; Thompson and Skerman, 1979).
