Trichoderma species are commonly used as bio-control agents against phytopathogenic fungi and some isolates are able to improve plant growth. In this study, effects of 9 Trichoderma strains in sunflower on photosynthesis, dry matter partitioning were examined. Plant height, number of leaves, days to 50% flowering, days to physiological maturity, Total Dry Matter, Photosynthetic Rate, SPAD Chlorophyll Meter Readings (SCMR), Leaf Area Index, Crop Growth Rate (CGR), Net Assimilation Rate (NAR), diameter of head, head weight, number of filled seed per head, 100 seed weight, seed yield and Harvest Index were studied by the application of Trichoderma strains.

Key words: Trichoderma species, TDM, Photosynthetic Rate, SCMR, CGR and NAR.
