Highest pH, moisture, and sodium content were in the PS compost, the highest nitrogen and calcium content was in the CGMW compost, and the highest potassium content was in the PS + CGMW compost. The highest population of thermophilic fungi and bacteria was in the PS compost, followed by the PS + CGMW compost. Predominant thermophilic fungi in different types of composts were Humicola insolens and Scytalidium thermophilum. The CGMW compost not only supported the fastest mycelial colonization and earliest first harvest (9 days) but also the highest mushroom yield in both trials (36.60 and 39.34 kg/q dry substrate). The next best mycelial colonization and first harvest of mushrooms were in PS + CGMW compost. However, mushroom yield was higher in PS + CGMW compost in trial 1 and PS compost in trial 2. The number of fruiting bodies did not show much variation in higher yielding substrates, and higher yield was a manifestation of significantly higher average fruiting body weight in the superior yielding substrate. The dry matter, protein, sodium, potassium, and calcium contents in the mushrooms varied with the compost as well as with the flushes: protein, potassium, and calcium were highest in mushrooms from the CGMW compost, sodium was highest in mushrooms from the PS compost, and dry matter of mushrooms was highest from PS + CGMW compost. %8 2009-11-16
