Button mushroom(Agaricus bisporus) are cultivated on wheat straw or rice straw based compost. In this study different compost formular, sawdust as carbon source and chicken manure as nitrogen source were used for button mushroom cultivation. Two steps of sufficient composting process was required to be successful in the cultivation. 1) the substrates are needed to be mixed periodically under the aerobic condition in the phase I process. 2) the temperature is need to be maintained between 55 and 65? for more than three days in the phase II process. Results showed that button mushroom was possible to grow normally with sawdust based compost. However the mushroom yield was less than that of the conventional compost formular(rice straw or wheat straw). The new compost formular developed from this study may be useful but further research may need to improve button mushroom cultivation more efficiently.
