Effect of Different Substrate Supplements on Oyster Mushroom (Pleurotus spp.) Production

To compare the effect of different agricultural wastes on growth and yield of mushroom production, three species of Pleurotus viz. P. sajor-caju (V1), P. ostreatus (V2), and P. djmor (V3) were grown on three different substrates cotton waste (T1), wheat straw (T2) and paddy straw (T 3). The fastest spawn running, primordial initiation, harvesting stage, maximum number of fruiting bodies and maximum yield was observed in T 1 took minimum number of days T3 showed maximum yield in 1st flush showing no significant differences with treatment T1 whereas T1 took maximum yield in 2nd flush and 3rd flush. P. djmor showed the highest percentage of dry matter (17.23%) and moisture content was found high in P. sajor-caju (87.37%). P. ostreatus and P. sajor-caju showed the maximum protein (27.23%) and fiber (26.28%) contents. The ash contents were found maximum P. sajor-caju (9.08%).The highest fat and carbohydrate contents were found in Pleurotus djmor (3.07%) and P. djmor (37.69) respectively.
