Evaluation of Different Substrates for the Production and Economics of Oyster Mushroom (Pleurotus ostreatus)

The experiment was carried out at Krishi Vigyan Kendra, Jaunpur of eastern Uttar Pradesh. during 2019. Oyster mushrooms draw their nutritional requirement from a host substrate or the agricultural wastes rich in lignin, cellulose and hemicellulose used for its cultivation. Nutrient content varied with the substrate which lead to varied mushroom yield. An experiment was conducted to evaluate commonly available agro-wastes viz., wheat straw, paddy straw, sugarcane leaves, sugarcane bagasse, stalks of maize, stalk of pearl millet for the cultivation of oyster mushroom (Pleurotus ostreatus). Among tested substrates wheat straw was found to yield more yield (710.50 g/ kg dry substrate), biological efficiency, net returns and benefit cost ratio than other treatments.
