Oyster mushroom (Pleurotu sp.) is the most commonly cultivated mushroom<br />

in Malaysia due to its delicious taste and high nutritional values; however the<br />

local production of mushrooms did not meet the requirement. In nature, oyster<br />

mushrooms fruiting under favourable conditions, especially after rain and<br />

thunderstorm. This study aimed to determine growth performance and yield<br />

production of oyster mushrooms treated with electrical stimulation (15V), free<br />

fall pressure (6.86 kPa), and acoustic sound (55-75 dB). These stimulations<br />

were used to mimic the natural events that signal the advantageous time for<br />

mushrooms fruiting. The results showed that free fall pressure required the<br />

shortest spawning time and produced the largest fruitbodies. This project has<br />

potential to strengthen scientific evidence of the effects of physical stimulations<br />

on mushrooms growth and helps to discover alternative techniques in<br />

mushrooms cultivation. Overall, the free fall pressure was the best treatment<br />

among three physical stimulations.<br />
