This study was carried out on the cultivation of five species of Pleurotus using fermentation substrate. Paddy (Oryza sativa) was used for spawn production. Five species of Pleurotus (identified and selected in the isolation process from mushroom farms in Lamdong province) with prepared compost were examined for time of spawn running, infection rate and biological efficiency. | Cultivation of oyster mushroom (Pleurotus spp.) using fermentation substrate
