Abstract
This study aims to use agricultural wastes rice stalk, bran and husk as alternative substrates for Pleurotus ostreatus. The study was done at Western Visayas Integrated Agricultural Research Center, in ratios of 50:50 and 100:0, wastes to sawdust respectively. After harvest, the masses were weighed, the caps counted, and the biological efficiency was measured. Rice stalk treatments had the highest biological efficiency while rice bran and hull treatments did not produce any caps for the first flush. The dry mass post hoc results showed significant difference amongst all substrates, proving that rice stalk treatments have the highest biological efficiency and are most compatible with P. ostreatus.
