YIELD AND BIOLOGICAL EFFICIENCY OF Pleurotus ostreatus (JACQ. FR.) CULTIVATED UPON VARIOUS WEEDS AND AGRICULTURAL WASTES
Waqar Islam and Asif Riaz
Oyster mushrooms are fleshy edible fungi which have acquired huge importance due to their nutritional and medicinal properties. These mushrooms are cultivated upon various substrates which directly affect their yield and biological efficiency. So the present experiment was designed to study different weeds, agricultural wastes and their mixtures for understanding their efficacy in enhancing yield and biological efficiency of oyster mushrooms. The yield of mushrooms was calculated up to three flushes while biological efficiency was recorded upon dry weight basis. Our results illustrated that cotton waste showed better performance as substrate as it yielded maximum oyster mushrooms in all the three flushes followed by Chenopodium album and mixture of cotton waste + Chenopodium album. These substrates also provided better results regarding Biological efficiency of the mushrooms by recording 92.90%, 83.34% and 75.77%, respectively. Hence, we conclude that Chenopodium album alone or mixture of particular weed and cotton waste can be utilized for efficient cultivation of mushrooms.
