The isolate Fusarium oxysporum F2 was selected based on its high production of growth regulator IAA and used in the present study .The optimal condition for the production of Plant hormone (IAA) by using cultural medium composed of 4.5% sucrose, 0.6% Yeast extract, 0.3g KH2PO4 , 0.05g MgSO4 , 3mM Tryptophane and optimum inocula size was 1×106 spore/ ml and the initial pH was 8.5 the incubation period was 10 day at 28 Co in dark by using shaker incubator at 120 rpm.
