Main objectives of study were to know the general characteristics of the mushroom producer, cost and return of each mushroom production as well as the production function and efficiency of input in producing Oyster mushroom and Pleurotus sp.. Collecting primary data from the crop year 1993 was conducted by interviewing producers in 4 regions; Northern, North-Eastern, Central, and Southern through questionaires. There were 122 samples. The result of the study shows that most of mushroom producers have experienced in producing mushroom approximately for 5 years, fifty seven percent of the sample have been producing mushroom as their main career. There are 7 kind of mushroom being produced: Oyster mushroom, Pleurotus sp., Ear mushroom, Abalone mushroom, Lentinus squarrosulus, Lentinus polychrous and Shiitake. These mushrooms can be cultured plastic bag containing sawdust. An analysis of cost and return found that the average cost of producing mushroom per kg ranged from 5-8 baht and the producer gets the net profit ranging from 8-12 baht per kg depending on the kind of mushroom. The average cost of producing spore bag was 3 baht per bag, and the net profit from selling spore bag ranged from 0.08-1.45 baht per bag. The estimation of Oyster mushroom and Pleurotus sp. production function by Quadratic form revealed that there are only 2 input factors that have significant impact on production namely, sawdust and labor. The total elasticity of the production at 1.17 indicated the increasing returns to scale. To maximize profit from these two kind of mushroom production, the increases in the use of sawdust and decreases in the use of labor must be adjusted to reach the optimum level.
