The utilization of low value agro-industrial wastes as a valuable end products has become a key research priority in the recent past. At present, in Malaysia, the commercial cultivation of Pleurotus ostreatus utilize sawdust from rubber tree (RS) as the base substrate. However. the high demand of rubber tree sawdust is leads to increasing price and has become a serious problem to mushroom grower's in Malaysia. In order to increase the food security in Malaysia, the an alternative substrates need to be explored. This research was undertaken to evaluate the performance growth and biological efficiency of sugarcane bagasse (SB) as an alternative substrate which is widely available in Malaysia for the cultivation of Pleurotus ostreatus. In this study, three different substrates were prepared either alone or in combinations in the ratio of 0.25 and 0.5 with RS. These substrates were supplemented with fixed ratio of wheat bran and limestone to increase the yield of Pleurotus ostreatus. There are four steps involved in cultivation Pleurotus ostreatus which were bagging, sterilization, spawning and harvesting the substrates. The mycelia growth, spawn run, pin head formation, yield and biological efficiency were observed. The 100% composition of (RS) gave the best yield in terms of the mean height of stipe 7.75cm. Mean fresh weight of sawdust was the highest with 50.4g and number of fruiting bodies around 6. The least yield was recorded with 50% composition of substrates with mean height of stipe 9.12cm. Among the substrates used, the (RS) showed the highest biological efficiency with 56.3% followed by 45.1% and 44.8% mixed composition of 25% and 50% substrates respectively. Hence, it proved that in terms of quantity and quality, the unmixed substrates produced better edible mushrooms. However, the results obtained show by (SB) also show a great potential as an alternative substrate for the cultivation of Pleurotus ostreatus when incorporated with rubber tree sawdust (RS).
