Abstract : Shiitake mushroom was cultivated on sawdust of timber plants babla, champa, garzon, ipil-ipil, jackfruit, mango, segun, shimul, shisoo, rain tree, sawdust mixtures and rice straw to test for growth and fruiting characteristics. Cultivation on jackfruit resulted in significantly faster mycelial growth compared to other substrates. Shiitake mushroom required 43 days to complete mycelial growth on jackfruit sawdust while requiring up to 55 days for other substrates. However with respect to fructification, jackfruit produced the first pinhead (primordium) significantly early compared to other substrates used. Number of primordia and effective fruiting body was also highest in mushroom raised on jackfruit sawdust. Yield attributes of shiitake mushroom such as stalk length, stalk diameter, pileus diameter and pileus thickness were significantly higher in mushroom raised on jackfruit sawdust. Biological efficiency, yields (biological yield, economic yield and dry yield) at first harvest and final harvest were highest on jackfruit substrate. The lowest biological and economic yields were found in mushroom raised on teak chambul. Rice straw, surprisingly, did not produce any fruiting bodies as well as showing no yield attributes.
