In: Mansoura University Journal of Agricultural Sciences 2009.v.34(2)Summary: The use of biofertilizers has become a great hope for Egyptian agricuiture, particularly in the field of production of medicinal plants, especially when the economic and environmental points of view are considered. since they reduce the environmental pollution and production costs, in addition to improving the quality. Therefore, the influence of using locally isolated nitrogen fixing bacteria as biofertilizers were studied. The isolates used were three representative strains of either Azotobacter and Azospirillum (two isolates of Azotobactar out of 60 isolates, these isolates were Az.NP7- AZ.PR1, and one isolate of Azospirillum out of 60 isolates, this isolate was As. Pp1 ) which were screened for their activity in nitrogen fixing and stimulation effect by used root exudates of black-cumin plants and used for further inoculation studies as biofertilizers.
