Pleurotus sajor-caju, mostly known as the grey oyster mushroom, is a popular delicacy in Malaysian dishes. Currently, the production of mushrooms is relatively low compared to the demand by the consumer. Therefore, cultivating the best mushroom strain with the best growth performance will alleviate mushroom production. This study evaluated the growth performance of two P. sajor-caju strains by measuring the mycelium linear growth and days for the mycelium to fill up the bag. The strains were cultivated in sawdust substrate supplemented with rice bran and calcium carbonate at a dry matter basis in the ratio of 100:10:1. The linear mycelia growth measurement was recorded every three days at intervals for three weeks. The result shows no significant difference (P>0.05) in mycelia growth and days needed to fill the substrate bag, as both strains took 22 days to fully colonise 12 cm substrate bags. However, the texture and density of mycelia exhibited by strain TK48 were more abundant and denser than strain TK60. Thus, the P. sajor-caju strains cultivated on sawdust produced similar mycelial growth performance.
