Abstract

Mushroom is an enlarged complex aboveground fleshy fruiting body of a fungus (such as a basidiomycete) that consists typically of a stem bearing a pileus especially one that is edible. Wheat bran, lime and sugar were used which serves as supplements and added to the sawdustwere varied into five treatments. The treatment (T1) consist of wheat bran, lime and sugar, treatment (T2) consist of wheat bran and lime, treatment (T3) wheat bran only, treatment (T4) lime only and fifth treatment (T5) wheat bran and sugar. One kilogram of substrate was used per bag. The protein content ranged from 25.12- 30.72% from the five treatments, while the moisture content in percentage obtained ranged from 73.42-79.35%. In terms of ramification of the bag placed in the dark room, all five treatments attained full ramification stage (100%) at fourth week. The analysis of variance carried out showed significant difference (P≤0.05) in yield (g/kg) of mushroom. Hence, T1 had the highest yield, followed by T2, T4, T3 and T5, with mean yield values of 141.65±7.86, 92.56±4.71, 86.96±3.45, 64.08±2.22 and 52.11±2.04 (g/kg) respectively. Range of 31.79-84.61% biological efficiency (BE) was obtained across the five treatments.
