Mushrooms have been identified as a relatively good source of nutrients. The<br />

demand for mushrooms is getting increased every year due to its nutritional<br />

benefits. On the other hand, Malaysians have generated massive amount of<br />

food waste every day. Therefore, alternatives to reduce food waste by reusing<br />

the leftovers as additional substrates in cultivation of mushrooms. This study<br />

aims of using food wastes as additional substrates to determine the effects on<br />

the yield, growth, moisture and ash content of grey oyster mushroom.<br />

Additional substrates such as eggshells (treatment A), banana peel (treatment<br />

B) and bagasse (treatment C) were treated in mushroom bags. Each waste was<br />

prepared in powder form and added to the standard substrate in mushroom<br />

bag. Each treatment A, B, C and control had 10 replicates. Treatment C showed<br />

the highest average number of fruitbody (6), followed by treatment B (6),<br />

treatment A (4) and control (3).<br />
