Abstract

• Mushroom is a crop which is cultivated in many countries using different agricultural wastes. This study was carried out to investigate the effects of paddy straw substrates on growth of Pleurotus ostreatus (Jacq. ex. Fr.) Kummer. The oyster mushroom, P. ostreatus (Jacq. ex. Fr.) Kummer was cultivated on paddy straw in polythene bags (containing 500 g paddy straw on dry weight basis per bag) using sorghum grain spawn. In this investigation, the substrate paddy straw yields a product average of 416g per bag. Therefore, it can be concluded that paddy straw is most suitable substrate for yield of oyster mushroom (Ngwe-Hnin-Hmo).
