The Effect of Cassava Peel Powder on the Productivity of the Brown Oyster Mushroom (Pleurotus cystidiosus)

Abstract

The oyster mushroom cultivation medium is generally sengon sawdust. As time goes by, there is a buildup of agricultural waste, one of which is cassava skin. Cassava peel contains nutrients that are in accordance with the nutrients needed as a medium for oyster mushroom cultivation. The purpose of this study was to determine the effect of a mixture of sengon sawdust and cassava peels with different weight ratios on the productivity of the brown oyster mushroom (Pleurotus cytidiosus). The research design used was a completely randomized design with 7 treatments, including M0, M1, M2, M3, M4, M5, and M6. Then the data were analyzed with One Way Anova using SPSS 20. The results showed that the M2 treatment (90% sengon sawdust + 10% cassava peel powder) had the highest average wet weight, namely 84.9 g, and the fastest pinhead appearance time, which was 40.2 days after inoculation. Then in the M5 treatment (75% sengon sawdust + 25% cassava peel powder), the highest average number of fruit caps was 22.8 fruit caps. And the One Way Anova test shows that all three parameters have F count > F table. Thus, there is an effect of adding media mixed with sengon sawdust and cassava peels with different weight ratios on the productivity of brown oyster mushrooms.
