This study collected data on MG2 Lingzhi mushroom production and its spores from six buildings, cov-
ering three crops, containing 30,000 bags, 34,955 bags and 32,032 bags per crop respectively. The total cost
was derived from the total fixed cost plus total variable cost.
The result of this study showed that the first crop of Lingzhi mushrooms producted were stem-shaped
and looked like deer antlers due to the fact they were grown in the winter. The cost of production was 10.97
baht per bag, or 1,135 baht per kilogram. The second crop was destroyed by fungus; it cost 6.22 baht per bag.
The cost of production for the third crop was 10.66 baht per bag or 1,168.99 baht per kilogram.
The overall cost of production for the 3 crops was 888,149.90 baht per year, 9.16 baht per bag, and
1,526.27 baht per kilogram. While dry Lingzhi mushroom in the Thai market costs 850 baht per kilogram, its
spores were priced at 2,000-100,000 baht per kilogram. Therefore, it will be possible for Muang Ngai Special
Agricultural Project to produce Lingzhi mushroom and its spores for commercial sale.
However, if the crops are promoted among farmers, the farmers must be taught skills in proper produc-
tion methods (good agricultural practices (GAP)) in order to be effective in producing this type of mushroom
and for selling it commercially.
Key words: cost of production, Lingzhi mushroom, Lingzhi spore, good agricultural practices (GAP)
