Efect of nitrogen fixing bacteria and Trichoderma on growth and yield of some vegetables

Abstract

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.
