Abstract The Present study was conducted in mushroom house to determine the effect of different substrates like saw dust, paddy straw and sugarcane bagasse on growth and production of Pleurotus ostreatus (oyster mushroom). Initially, the stalk length and pileus diameter of oyster mushroom was recorded . Among the three treatments, the maximum stalk length (6.87± 2.10) and pileus diameter (6.41± 0.60) was observed in paddy straw treatment followed by saw dust (4.40± 0.05),(5.50± 0.06) and sugarcane bagasse (3.14 ± 0.77), (4.48± 1.41). Mycelium running took less time i.e. 11 days on paddy straw as compared to sugarcane bagasse (12.33) and saw dust (15.33). The appearance of pinhead and their maturity also took less time i.e. 17 days and 22 days, respectively on paddy straw and sugarcane bagasse. The maximum number of fruiting bodies were observed in paddy straw treatment (12.33) and saw dust treatment ( 10.66). The highest yield was recorded on paddy straw ( 41.66± 17.55) followed by sugarcane bagasse ( 32.1±16.70) and saw dust (19.24± 11.13) treatment. Among the three different substrates tested, paddy straw substrate was recorded in better growth and yield of Pleurotus ostreatus.
