Cultivation of oyster mushroom [Pleurotus ostreatus (Jacq.) P. Kumm] through substrate enriched with tea waste

A study was conducted to assess yield, biological efficiency and nutritional contents of Pleurotus ostreatus on different formulations of wheat straw, sugarcane bagasse, coconut green husk, banana pseudostem and waste paper mixed with tea waste, lime, gypsum and sucrose at various proportion. The data showed the maximum yield of Pleurotus ostreatus on wheat straw + tea waste + lime + gypsum + sucrose (711.6 g/kg substrates) and sugarcane bagasse + tea waste + lime + gypsum + sucrose (702.3 g/kg substrates). The nutritional contents of the mushroom grown on mixed substrates were comparatively higher as compared to control. Mix substrates gave the maximum protein content (27.316 mg/g), total sugar (27.670 mg/g), phenol (1.952 mg/g), Moisture (91.6 %).
