ABSTRACT: Effects of various sawdust substrates, namely Fig tree (T2), Rain Tree (T3), Mahogany tree (T4), Ipil ipil tree (T5), Eucalyptus tree (T6) and mixture of all sawdust (T1), supplemented with 30% wheat bran and 1% lime were analyzed on the growth and nutritional composition of Pleurotus ostreatus mushroom. The highest amount of carbohydrate (42.36%), calcium (31.98 mg/100g) and magnesium (19.85 mg/100g) were found in the T4 sawdust substrate treated mushrooms. Whereas, moisture (90.20%), ash (13%), phosphorous (0.91%) and molybdenum (14.76 mg/100g) were highest for the T1 substrate treated mushrooms. The highest amount of dry matter (10.53%), lipid (4.46%), nitrogen (4.52%), iron (42.55 mg/100g), zinc (27.65 mg/100g) and selenium (6.77 mg/100g) were obtained for T2 substrate treatment. The highest amount of crude fiber (20.53%) and the lowest lipid (3.43%) was found for T6 substrate. Protein (27.30%) and potassium (1.28%) were found to be highest for T5 substrate treatment. However, the highest level of cobalt (22.40 mg/100g) was found for T3 substrate treatment. Among all aspects, best nutritional composition containing mushroom was grown on T2 sawdust substrate, followed by T1, T5, T6, T3 and T4.

KEYWORDS: Pleurotus ostreatus, edible mushrooms, nutrition, proximate composition, saw dust, wheat bran.
