Various percentage concentration of wheat bran was used to
examine their effect on yield of mushroom in terms of total
and average yield. Wheat bran was added to saw dust the main
substrate medium used for mushroom growth.
The treatment used are control, 2.5%, 5%, 7.5%, 10%, 12.5%, 15%, 17.5% and 20%.
Six replicas of each treatment was made, sterilized and inoculated with spores of (Pleurotus ostreatus) mushroom. Data was collected over a 30 day period. Data obtained were analysed statistically using Duncan multiple range test (DMRT) at 5% level of probability. Results indicate a gradual increase in both total and average yield of mushroom from 2.5% to 12.5%. The highest growth yield (average) of 22.78g and total yield of 683.5g was observed for 12.5% wheat bran concentration. Also, after 12.5% of wheat bran concentration both average and total yield declined sharply due to contamination of the fruiting bags.
Consequently, higher nutrient concentration above 12.5% favoured the growth of competing organisms which cause spoilage. The study indicated that best results in terms of yield can be obtained by using wheat bran concentrations of 7.5% to 12.5%.
