EVALUATION OF MYCELIAL GROWTH OF OYSTER MUSHROOM (Pleurotus ostreatus) FROM CASSAVA AND TARO PURE CULTURE MEDIA IN CRACK CORN

Abstract

The study aimed to evaluate mycelial growth of cassava + agar and taro + agar OM pure culture in cracked corn subculture media. Pure culture from cassava + agar (treatment 1) and taro + agar (treatment 2) were used in the inoculation of subculture media.
The data gathered was compared using T-test. The evaluation of the first mycelial growth appearance from inoculation in two treatments exhibited significant difference with an average of 1.33-day period in treatment 1 and 2.33-day period in treatment 2.
The analysis in number of days from inoculation to full mycelial colonization also showed significant differences. The shortest time was recorded in treatment 1 with average of 9.53-day period followed with an average of 10.76-day period for treatment 2. The result confirmed the result of Stanley and Nyenke (2011) that the cassava stimulated luxuriant mycelial growth rate and extension.The use of cassava + agar pure culture in oyster mushroom subculture production was recommended for its faster response to the cracked corn subculture media due to its fast mycelial growth.
