A ten millimeter disc of Trichoderma harzianum Rifai was utilized in this study. Growth response of the test organism was evaluated in potato dextrose agar and nine selected indigenous culture media. Six out of nine indigenous culture media produced a significant growth in the test organism. Mycelia of Trichoderma harzianum Rifai proliferated the plate of sawdust sucrose gulaman, coconut water sucrose gulaman and rice washing sucrose gulaman; and the plate of corn grit sucrose gulaman, sugarcane bagasse sucrose gulaman and rice straw sucrose gulaman with an average of three days and 3.6 days, respectively. Potato dextrose agar (control medium) took four days to be fully ramified by the test organism. The longest duration of mycelial proliferation was noted in water sucrose gulaman with an average of 9.6 days. Moreover, coconut water sucrose gulaman and potato dextrose agar produced the highest number of spores with a mean of 10.9 x 10 and 10.3 x 10, respectively. Statistical analysis showed insignificant difference between the two culture media.
