The results showed that six isolates of the total fungal isolates, as well as the isolate are : (A-12) A. flavus, (A-5) A. fumigatus, (A-S-7) A. flavus, (A-7) A. fumigatus, (A-J-1) A. niger in addition to (T-13) Trichoderma hamatum, which considered the best effective in promoting growth of cucumber plants according to plant growth criteria that studied such germination percentage, number of rotting seed, number of health and rotting seedling, first true leaf emergence date , relative content of chlorophyll, length and wet and dry weight of root and shoot and vigour index (VI) of seed.
