Utilization of Different Locally Abundant Materials as Substrates for Oyster Mushroom (Pleurotus Ostreatus) Production Under CAPSU-Tapaz Conditions

Abstract

These studies were conducted from June 17, 2019 to September 27, 2019 at the Tissue Culture Laboratory of Capiz State University, Tapaz Satellite College to determine the effects of using different locally abundant materials as substrates on the production of oyster mushroom under CAPSU Tapaz conditions. The experimental design used in the study was Completely Randomized Design with four treatments each replicated four times. The treatments for study 1 were as follows: A – 50% sawdust + 25% rice hull + 23% rice bran + 1% sugar + 1% lime (control), B – 78% sawdust + 20% rice bran + 1% sugar + 1% lime, C – 50% corn cob + 30% sawdust + 18% rice bran + 1% sugar + 1% lime, D – 50% rice hull + 28% sawdust + 20% rice bran + 1% sugar + 1% lime. For study 2 treatments consisted of: A – 50 % rice straw + 50 % sawdust (control); B – 78% rice straw + 20% rice bran + 1% brown sugar + 1% lime; C – 50% rice straw +29% sawdust + 20% rice bran + 1% lime; and D – 90% rice straw + 10% rice bran. The data gathered were analyzed using the Analysis of Variance and F-test for Completely Randomized Design. Differences among treatment means was determined using Least Significant Difference test, interpreted at 5% and 1% levels of significance.
