Among the nine substrates for the cultivation of oyster mushroom,
wheat straw and rice straw gave the faster mycelial
growth rate, time to primordial formation, time to first crop
than cotton seed hull, however, this did not correspond with
mushroom size and yield.
Oyster mushroom on rice straw and wheat straw substrate
in the present study have much low yield and BE, similar to the
results of Zhang et al. (2002), but lower than some reported
