Dired Cassava Chip as a Growth Substrate Supplement for the Cultivation of Phoenix Mushroom (Pleurotus sajor-caju)

Abstract

Using pararubber sawdust as the base substrate, different levels of dried cassava chip supplement were compared with the standard substrate (comprising 95 percent sawdust, rice bran, MgSO4and CaCO3) for suitability for growing Pleurotus sajor-caju. The sawdust : cassava chip combinations studied were 100:0, 90:10, 80:20, and 70:30; a substrate comprising 95 percent sawduct and 5 percent rice bran but without the addition of MgSO4and CaCO3, was also tested. The results demonstrated that a growth substrate comprising sawdust and between 20 and 30 percent dried cassava chip was capable of giving a yield comparable to that obtained with the standard substrate.
