Abstract
The effects of two different substrates, sawdust and coconut residue and mixture ratios on oyster mushroom cultivation were determined. The mycelium growth was unable to completely colonized the coconut residue substrates. Percentage of mycelium colonized on the substrate was reduced when percentage of coconut residue supplemented in cultivation substrate was increased. Even the mycelium growth was not totally colonized the coconut residue substrates but the mass of whitish mycelium was thick, dense and comparatively compact when compared to sawdust (control). A substrate combination of 25% coconut residue + 75% sawdust accelerated the mushroom growing processes and gave the highest in both mushroom yield (559.67 g) and percentage Biological efficiency (BE; 109.80%). Even the substrate combination of 25% coconut residue + 75% sawdust gave the maximum mushroom yield but this yield was insignificantly different to those found from 100% sawdust (536.85 g). Least yield (278.78 g) and low BE (56.76%) were revealed from coconut residue alone and these values were significantly different to those found in all cultivation substrates at a confidence level of 95%. For oyster mushroom (Pleurotus ostreatus) cultivation, it is clearly indicated that the by-product waste such as coconut residue can be used as a supplementation material with sawdust and the appropriate ratio added should not be exceeded 25%.
