Cassava peel based substrate formulations as an alternative substrate were used to grow mushrooms. The effect of two compost heights, three composting periods on the mycelia growth, physical characteristics, yield, and nutritional qualities of Pleurotus ostreatus (Jacq. ex Fr.) Kummer was studied. Mean mycelia growth of 16.2 cm after a period of seven (7) weeks was the best for 1.5 m compost height. Cap diameter and stipe length differed significantly (P < 0.05) with the compost heights (0.8 m and 1.5 m). The yield on compost height of 1.5 m, composted for 5 days, differed significantly (P < 0.05) from that of 0.8 m and gave increasing yields as follows: cassava peels and manure, cassava peels only, cassava peels and corn cobs (1 : 1 ratio), and cassava peels and corn cobs (1 : 1 ratio) with chicken manure. Composting periods (3 and 7 days) gave varying yields depending on the compost height. Based on the findings an interaction of 1.5 m compost height and 5 days composting period on cassava peels and corncobs (1 : 1 ratio) with chicken manure produced the best results. The nutritional quality of the mushrooms also differed significantly (P < 0.05), indicating that cassava peels could be used as a possible substrate in cultivation of mushroom.
以木薯皮为基础的基质配方作为替代基质用于种植蘑菇。研究了两种堆肥高度、三个堆肥周期对平菇（Jacq. ex Fr.）Kummer菌丝体生长、物理特性、产量和营养品质的影响。对于1.5米的堆肥高度，七（7）周后的平均菌丝体生长为16.2厘米，这是最佳效果。菌盖直径和菌柄长度因堆肥高度（0.8米和1.5米）而有显著差异（P < 0.05）。堆肥高度为1.5米、堆肥5天的产量与0.8米的产量有显著差异（P < 0.05），产量增加顺序如下：木薯皮和粪肥、仅木薯皮、木薯皮和玉米芯（1∶1比例）、木薯皮和玉米芯（1∶1比例）加鸡粪。堆肥周期（3天和7天）根据堆肥高度产生不同的产量。基于这些发现，1.5米的堆肥高度、5天的堆肥周期以及木薯皮和玉米芯（1∶1比例）加鸡粪的组合产生了最佳结果。蘑菇的营养品质也有显著差异（P < 0.05）,表明木薯皮可作为蘑菇栽培的一种可能基质。
