Growth and productivity of oyster mushrooms (Pleurotus ostreatus) on media rice straw mixed with sawdust

Abstract

Pleurotus ostreatus can be cultivated in a medium derived from wood dust or lignin which has been weathered and wrapped in plastic. The purpose of this research is to measure the effect of the composition of rice straw mixture on white oyster mushroom growing media on the growth and productivity of white oyster mushrooms (P. ostreatus) and get the best composition of planting media for growth and productivity of white oyster mushrooms (P. ostreatus). The research design used was a Completely Randomized Design consisting of six treatments. The treatment used is the composition of the planting media with a mixture of rice straw 0, 10, 20, 30, 40, and 50%. The results showed that the mixture of rice straw resulted in mycelium growth and the age of harvest began to be longer. The composition of the best growing media for growth and productivity of white oyster mushrooms is a mixture of 30% rice straw (300-gram rice straw + sawdust 550 grams).
