Oyster mushroom (Pleurotus Ostreatus) on sawdust substrate. Due to the decreasing supply of sawdust, there was an urgent need to identify alternative substrates. This study aimed to evaluate palm oil husk as an alternative substrate for oyster mushroom cultivation. The first step was to assess the growth of oyster mushroom mycelium on palm oil husk extract. Antifungal substances found in palm oil husk slowed mycelium growth but did not turn it off. The positive results obtained, substrate mixtures containing different proportions of palm oil, grass, tea waste in a mushroom bag. The substrate containing 70 palm oil husk, and 30% of tea wastes showed promising results in terms of mycelium growth. This substrate was select for further trials with lime. The highest yield of mushroom obtained with a substrate mixture supplemented with 0.05% lime. Results obtained showed that palm oil husk could be successfully used to cultivate oyster mushroom, but it needs mixing with tea wastes for the source of cellulose. Substrate mixture which contained palm oil husk and tea waste, supplemented with lime, indicate the most promising outcome in term of yield percentage.
