YIELD PERFORMANCE OF MUSHROOM (Pleurotus ostreatus) ON DIFFERENT TREATMENT OF SUGARCANE BAGASSE AND SAW DUST AND ITS NUTRIENT ANALYSIS

Pleurotus ostreatus has more economic, ecological values and medicinal properties. Huge amounts of ligno – cellulosic agricultural crop residues by products rich in organic compounds are annually generated. This study was conducted to compare effects of different concentration of sugarcane bagasse, saw dust and nitrogen source (wheat bran, cauliflower leaves and ammonium sulphate) on growth and bioconversion efficiency of oyster mushroom. In the present study the parameters such as days, spawn run, primordial formation, harvest days, total yield and biological efficiency were evaluated. The utmost substrate was found to be T1 (Sugarcane bagasse+ Saw dust + Wheat bran) in terms of spawn run (16 days), primordial formation (24 days), average number of fruiting bodies (116), stem length (6 cm) and cap diameter (20.5 cm). Total yield of Pleurotus ostreatus on different treatment substrates T1, T2 and T3 was found as 266.23±2.52g, 248.7±2.41g and 234.18±2.35g respectively. The biological efficiency of Pleurotus ostreatus was found high in T1 (86.28±8.51%) followed by T2 (78.41±7.80%) and T3 (74.25±7.40%). The protein (3.80%), fat (0.008%), carbohydrate (7.61%), crude fibre (6.01%) and ash content (0.80%) found maximum in T1 than T2 and T3.
