Mushroom, as believed by many people, grows on specific time and condition as in the wild it grows after a heavy rain falls. The effects of lightning and thunderstorm may suppress the mychorrizal structure to grow and eventually forming fruiting body. This study was conducted to determine the effect of different acoustic sound treatments on the growth and yield of grey oyster mushroom (Pleurotussajor-caju). Five different acoustic sound treatments had been applied during spawning period which were thunder storm, hardcore music, soothing instrumental, Quranic recital and without any sound treatment applied which served as control. The parameters studied were mycelium growth rate, days of mycelium filled up the bags, days of pinhead emergence, days of fruiting body formation, total weight, percentage biological efficiency, pileus color and texture. There were significant differences (P<0.05) in the mycelium growth among different acoustic sound treatments where sound treated mushroom showed faster growth than control. Similar trend was also observed in yield (total weight and biological efficiency) where there were significant differences (P<0.05). However, there were no significant differences (P>0.05) observed in other parameters, such as pinhead emergence, fruiting bodies formation, pileus color and texture. In summary, treatments using different acoustic sound at 75 dB could be considered as better treatment to enhance the mycelium growth thus accelerate the mushroom cultivation process as well as increasing the mushroom productivity. This research could help farmers to grow and harvest their mushroom at specific time frame and fulfill customer’s demand.
