Nitrogen fixing efficiency all of the isolates was determined by microkjeldhal method and the nitrogen fixing efficiency ranged from 10.03 to 13.11 mg N/g substrate. The growth of <em>Azospirillum </em>isolates was significant affected by different physiological factors such as pH, temperature and salinity. Most of the isolates showed optimum growth at pH 6.8, temperature 37°C and in the absence of NaCl. <em>Azospirillum </em>has the potential to be used as a substitute and or supplement of N-fertilizers. Further research is needed to estimate N-supplement potentials of biological nitrogen fixation (BNF) systems at the farm level.</p><p>Jahangirnagar University J. Biol.
