The experiment was set up by using a completely randomized design, replicated three times. The experimental results showed that the number of conidiumon mixed media ela sago + bran and ela sago + bran + husk reached up to 1011 per g media and significantly greater than that of ela sago, elasago + husk, Husk + bran, husk, bran, and corn media.
