In the MD of Vietnam, one of the popular uses
of rice straw is for mushroom production.
An assessment for this practice was done recently to find the role
of the collection cost in this production,
which resulted in the cost components shown in Fig. 6.
The rice straw cost, including collection and transportation (50 km),accounted for 25.8%
of the total investment cost; net profit of mushroom
production using 1 ton of straw was US$123 (±14).
