Abstract :

The objective of the study aimed to compare the yield effect of edible mushroom Pleurotus ostreatus by agro wastes (Paddy straw, sugarcane bagasse, Coconut sawdust and Banana leaves) as substrates for its low cost commercial production. The moist substrates were sterilized and packed in heat resistant plastic bags seeded with 8 – 10% of spawn. Over the spawn, a layer of substrate was overlaid and the process was repeated for 6–7 layers and incubated for 2 to 3 months. Different growth parameters such as spawn running time, fresh weight, temperature and humidity, yield rate were evaluated for each substrate with three replicates. The result of this study indicates, paddy straw and sugarcane bagasse was found to be the better substrate for high yield. Even at 70 to 80% of humidity and 25–27ºC banana leaves, coconut saw dust showed less yield. Summary : In this study concluded that the four different agro–wastes used as substrates for Pleurotus ostreatus production. In which, comparatively the higher flush yields were obtained in paddy straw and sugarcane bagasse than banana leaves, coconut sawdust.
