For each of the treatments, two flushes were harvested during the study. The study revealed that different substrates showed varying yields and BE with or without supplements. Yield, mushroom size and BE are presented in Table 3. In the first flush, maize stalk yielded 213.17 g, 158.96 g, and 156.50 g with rice bran, control and chicken manure respectively. The total yield in maize stalk with rice bran was 348.13 g followed by 280.66 g and 271.57 g in control and chicken manure respectively
