production and trade of oyster mushroom is meager, being only an
estimated 2000 t, the potential for the future is rated as high for a variety

straw, paddy straw, bagasse, chicken manure, tea waste, and de-oiled
cakes are easily available all over India and can therefore be most suitable
and inexpensive substrates for expanding future cultivation.
