Labor required for managing and harvesting the oyster mushroom bed was evaluated. Although vinyl mulching cultivation method needs more hours for spawning, it saves more than 50% of labor for harvesting and managing of the mushroom bed. Harvesting hour of 1st-3rd flush in vinyl mulching method was 48~50% for Plerutus ostreatus and 36~41% for P. sajor-caju. Labor for bed management after harvesting in vinyl mulching method was also 38~50% for P. ostreatus compared to conventional method, and 20~35% for P. sajor-caju. Vinyl mulching is believed to be a very efficient method for saving labor in oyster mushroom cultivation.
