Abstract

This research aimed to study the effect of grain spawn amount on rice straw treated with cold fermentation and lime bath treatment. The study found that rice straw prepared by cold fermentation and lime bath treatment could be used to cultivate oyster mushroom. It was found that cold fermentation rice straw with 5, 10, 15, and 20 percent grain spawn and lime bath treatment rice straw with 5, 10, 15, and 20 percent grain spawn showed different mushroom yields when compared with rice straw prepared by steam pasteurization. The yields were 19.13 26.73 31.97 38.15 31.05 48.15 51.00 63.98 and 79.15 grams, respectively. The results may reflect the different in the contamination percentage of the mushroom bags which are 53.33 26.67 26.67 86.67 60.00 20.00 20.00 and 0.00 percent, respectively. Therefore, it can be concluded that the substrate prepare by lime bath method with 20 percent grain spawn can be use in commercial mushroom production. This due to the similar yield to control and lowest contamination percentage in all methods except control.
