Abstract
Ten isolates of nitrogen fixing bacteria were isolated from roots of wheat,barley and tomato grown in different areas in south of Iraq. Isolated bacteria were puried then identified .Results indicated that all isolates belong to Azospirillum genus and Lipoferum species .Nitrogenase activity differs for all isolates ranged from 112.19 to 803.07 nmole .ml-.hr-. highest activity were associated with isolate A3 while the lower activity was associated with isolate A4 . Results showd that difference efficiency in nitrogenase activity for different isolates with in genus and species habited same plant
