Nitrogenase activity (C2H2 reduction) was found to be associated with the following grasses in the field: Agropyron dasystachyum, Agropyron smi thi i , Aristida purpurea, Oryzopsis hymenoides and Stipa comata. Uptake of fixed nitrogen was also demonstrated for these grasses. Two unidentified nitrogen fixing bacteria were isolated, one from Stipa comata and one from Aristida purpurea. Cynodon dactyl on and Agropyron cristatum were successfully inoculated with the unknown isolate obtained from Stipa comata. The inoculated plants exhibited nitrogenase activity (C2 H2 reduction) whereas uninoculated controls gave negative results.
