Abstract: This paper discuss about the growth rate and production of Indole Acetic Acid (IAA) by several fungal rot isolates collected from decayed cacao plants. Growth rate of isolates was revealed on media Malt Peptone Agar (MPA), on petridish ( 9 cm), measured based on the colony diameter daily until 7 days. BSA isolate reaches a maximum diameter on day 3, while the other isolates reached the maximum growth on the day 4th and 7th. The production of IAA was examined on Pikovskaya broth media and measured using spectrophotometer. The study showed that the fungal rot have ability to produce Indole-acetic acid (IAA). The IAA concentration range between 0.349-2.794 g l-1. The BSA, BPB, and BSF isolates had the highest concentration of IAA.
