Growth and productivity of mushroom oyster (Pleurotus ostreatus) on mixed planting media of cocopeat with sawdust

Mushroom oyster (P. ostreatus) is one of wood type fungus commonly consumed by the community. Mushroom oyster cultivation is usually performed by planting media of sawdust. The chemical composition of the cocopeat lignin (45.8%), cellulose (43.4%), hemicellulose (10,25%), and pectin (3.0%). The advantage of using cocopeat is high waters retention and light weight. The research design of Randomized Design (RAL) was used consisting of 6 treatments, control, 10% cocopeat, 20% cocopeat, 30% cocopeat 40%, and 50 consisted of 5 replications in which each replication consisted of one % cocopeat. Each treatment was applied on baglog of mushroom oyster seedlings. The data obtained was analyzed by one way analysis (ANOVA) with 95% confident of level. If any significant influence on the treatment was detected, then it was continued with Duncan's Multiple Range Test (DMRT) with 95% level. The best planted treatment for mushroom oyster's growth was P5 treatment with a composition of 50% cocopeat because it has a higher wet weight than all treatments. The environment also affected mold growth. If the air temperature is high then the production of mushroom oyster is higher, and when the moisture is high then the mushroom oyster production is also greatly increased.
