Effect of Different Sawdust Substrates on the Growth, Yield and Proximate Composition of White Oyster Mushroom (Pleurotus ostreatus)

The present study was to analyze the effect of different saw dust substrates namely Magifera indica (Mango tree, T1), Albizia saman (Rain tree, T2), Tectona grandis(Segun tree, T3), Gmelina arborea (Gamari tree, T4), Swietenia mahagoni (Mahogony tree, T5 ) and mixture of all five tree sawdust (T6) with wheat bran 30% and 1% lime on the growth, yield and proximate composition performance of Pleurotus ostreatus (white oyster mushroom). The experiment was laid out in single factor Completely Randomized Design (CRD). The highest average number of fruiting body per packet (57.20) was observed in T5, whereas the lowest (47.00) was found in T2. The highest average weight of fruiting body (4.45 g) was observed in T5 while the lowest (3.76 g) was recorded in T4. The highest biological yield (227.68 g) was found in T5, while the lowest (204.78 g) was observed in T4. The highest economic yield (207.58 g) was recorded in T5, while the lowest (181.96 g) was found in T4. The highest BCR (4.25) was observed in T5, whereas the lowest (3.62) was found in T4. The highest moisture content (87.77%) was observed in T4, while the lowest (85.84%) in T5. The highest dry matter content (14.16%) was observed in T5, whereas the lowest (12.23%) was recorded in T4. The highest protein content (24.97%) was found in T5, while the lowest (24.12%) was observed in T4. The highest lipid content (6.15%) was observed in T5, while the lowest (5.72%) was recorded in T4. The highest calcium content (17.33 mg/100 g) was found in T6, while the lowest (15.72 mg/100 g) was recorded in T4. The highest magnesium content (14.50 mg/100 g) was observed in T5, while the lowest (13.35 mg/10) was observed in T4. The highest iron content (47.46 mg/100 g) was found in T1, while the lowest (44.89 mg/100 g) was recorded in T4.
