Abstract
The influence of 15 kGy dose of gamma radiation on the performance of eight lignocellulose agro-wastes for mushroom (Pleurotus eous, P-31) cultivation was evaluated. The agro-wastes investigated included coconut coir, rice husk, rice straw, banana leaves, cassava peels, corn cobs, elephant grass and sawdust (control). Corn cobs performed overall best with 23.2mm/day, 13 days, 9 days, 0% and very dense for spawn running parameters studied which were the rate of mycelia colonization, time taken to complete colonization, percentage contamination and mycelia
density respectively. Also recorded for growth parameters were 95mm for cap diameter, 80mm for stipe length, 52 for number of primordia, 51 for number of fruit bodies, 6.5 for mushroom size and 9days for time between flushes. The biological efficiency (B.E %) was 63%, mushroom yield was 377g and biological yield recorded was 0.63 g/g substrate. The gamma irradiated substrates significantly (p<0.05) influenced both growth and yield of mushroom differently. The results of this study revealed that gamma irradiation could be used as an alternative method for the pretreatment of lignocellulose agro-wastes substrates for mushroom cultivation.
