Field experiment was conducted in Agricultural Research site in Baghdad using nitrogen fixing bacteria (Azotobacter)and Trichoderma during planting of tomata and eggplant crops.Results showed a clear differnce of growth and yield parameters for all treatments used. The treatment of the mixture of Azotobacter and Trichoderma was the best which increased the dry weight to 240g/plant and yield to 2050g/plant comparing with control (175,1100/plant)respectivelly for tomata,while dry weight and yield for eggplant increased to 200,1900g/plant comparing to control treatment which recorded 110,1300g/plant respectivelly.
