This study was conducted to provide a fundamental information for a income raise of agricultural and mountain villagers and a policy planning by analyzing I45 chestnut producing farms in Korea. The results of this study are as follows : 1. Though the proportion of forest by-products in #arm household economy was very slight, it is very important for agricultural and mountain villagers who have relatively lower income level to become a valuable income source. 2. As chestnut cultivating orchards have very small-scale that account for 50.0% of 0.5 to 1.0 hectares and 40.3% of 1.0 to 3.0 hectares reaching 90.3% of total farmers, the small-scale ownership makes the normality and rationalization of management difficult, and therefore the economity of scale has to be accomplished. 3. The difficulties on chestnut cultivating management were in order of the following ; Labour-power shortage(38.5%), desease and pest demage(24.8%), economity(15.2%), management(11.7%), inferiority of site condition(5.9%), technical acquirement(3.8%). 4. In the matter of storaging facilities, 87.6% of total surveyed farmers were recognizing the need of storaging facilities, but only 12.4 of surveyed farmers were possessing these facilities, and therefore the measurement has to be considered such as the forest associations invests to cold storaging facilities unable to privately invest, in order to increase a receiving price of producers.
