This study was conducted to evaluate the efficiency of three local isolates of the fungi Trichoderma spp.(T.9,T.26,T.28) in increasing availability phosphor and some micronutrients (Mn, Zn, Fe and Cu) as one of the supposed mechanism of growth enhance.
The results revealed the ability of the three tested isolates in increasing the solubility of Rock phosphate and increasing the (P) availability which recorded (0.53,1.34 and 1.57) mg/ L respectively compared to 0.02 mg/L at in control treatment.
Results also showed that isolates T.9,T.26 and T.28 soluble of MnO2in broth culture (3.46 ,3.03 and 3.o3 )mg/L and ZnO (37.63, 31.63 and 36.62 ) mg /L as compared to (28.7and 2.3 ) mg/L for two element in control treatment.
No increment in Cu and Fe solubility was recorded .
