Abstract

Despite the abundance and potential of agro-waste materials like cassava peels and corn cobs, these materials have not been extensively utilized as substrates for cultivation. This study therefore explored the use of corn cobs, cassava peels and rice straw as substrates for oyster mushroom (Pleurotus ostreatus) and milky mushroom (Calocybe indica) cultivation. The objective is to evaluate the effectiveness of these materials as substrates in enhancing growth by assessing fruiting body yield, biological efficiency and size of caps. Compost bags made with the different agro-waste materials were inoculated with spawns of the different mushroom species and were monitored for mycelium growth and appearance of fruiting bodies. Measurements were taken to determine yield, number of fruiting bodies, diameter of caps and biological efficiency. “Rice straw achieved 78.89% biological efficiency for C. indica. Analysis of variance and Duncan’s post hoc test showed no statistically significant differences in number of fruiting bodies and diameter of caps of C. indica and P. ostreatus on the different substrates. However, statistically significant differences were observed in the yield and biological efficiency. Mushrooms with high biological efficiency often have better nutritional profiles and functional benefits, making them more desirable. The yield recorded corresponds to the biological efficiencies observed.
