The effect of inoculation of Azospirillum brasilense individually and in combination with different levels of nitrogen on Oryza sativa L. was studied under sand culture condition during autumn season of 2007 in Tripura. The results showed that individual or combined effect of Azospirillum brasilense and nitrogen fertilizer both at high and low levels has significantly increased the in vivo nitrate reductase activity, total protein and chlorophyll content compared to control. These parameters were found enhanced in plants supplemented with nitrogen fertilizers and inoculated with Azospirillum brasilense.
