STUDY ON SUPPLEMENTATION OF WHEAT BRAN WITH SUGARCANE BAGASSE ON YIELD AND PROXIMATE COMPOSITION OF OYSTER MUSHROOM (Pleurotus ostreatus)

Abstract

The present study was carried out during the period of February to July, 2009 to investigate the performance of different levels of wheat bran as supplement with sugarcane bagasse on the production of oyster mushroom and analysis of their proximate composition. The highest mycelium running rate was observed due to sugarcane bagasse supplemented with wheat bran @ 40% (T ) (0.96 cm). The highest time from stimulation to primordia initiation was observed in T 5 days). The lowest time from primordia initiation to harvest was in the treatment of T4 (3.23 days). The highest average number of primordia/packet (70.67), average number of fruiting body/packet (61.00) was observed in the treatment of T . The highest average weight of individual fruiting body was observed in the treatment of T (3.69 g). The highest biological yield (254.7 g), economic yield (243.3 g), dry matter (23.40 g), biological efficiency (87.82%) and cost benefit ratio (8.29) was counted under treatment of T 4 . The highest moisture content (90.45 %) was observed in T 5 4 where as the highest dry matter percentage of (10.07 %) was found in the fruiting body of T . The highest content protein (30.31 %), ash (9.15 %) and crud fiber (24.07 %) and the lowest lipid (3.90 %) and carbohydrate (32.57 %) was found in the treatment of T 2 4 . The highest percentage of nitrogen

1 (11.5 5 (4.85), potassium (1.39g/mg), calcium (22.08mg), magnesium (20.21mg), sulfur (0.042g/mg), iron (43.11mg) was counted under T but the highest percentage of phosphorus was counted under treatment of T 4 (0.92). Therefore, it can be concluded that sugarcane bagasse supplemented with 30% wheat bran can be further used as a better substrate for oyster mushroom production reducing cost and increasing the yield and nutritional quality. 1
