In this study, I aimed to suggest political data on the plantation of chestnut trees given the local features by conducting an analysis on the economic efficiency of the plantation of chestnut trees aimed at chestnut tree plantation farmhouses (total 67 farmhouses) in Chungbuk, Chungnam, Jeonbuk, Jeonnam and Gyeongnam, which are the chief producing place in Korea. As a result, the central area (Chungbuk, Chungnam) was proven to post 2.7 times as many as the average total income, 3.9 times as many as income, and 12.1 times as many as net income per ha when compared with those in the southern area (Jeonnam, Gyeongnam). That is, the southern area demonstrated a very low economic efficiency on the plantation of chestnut trees compared with that of the central area, and this was caused by the reduction of chestnut production and the degradation of chestnut quality due to the aging of chestnut trees. Therefore, it is imperative to consistently renovate aged chestnut orchards and manage them in the southern area.

작물은 그 종류에 따라서 지대에 따르는 적응성에 차가 있는 것인데 이것은 작물종류에 따라서 각각 적합한 자연적, 사회적인 조건이 다르기 때문이다. 현재 각지에 조성되어 있는 여러가지 종류의 작물의 주산지는 그 대부분이 오랜 시일에 걸쳐서 그 지대에 적응하므로 써 자연적으로 형성된 것이다. 근래 일부에서는 인위적으로 어떤 작물의 주산단지가 조성되는 경우도 있기는 하지만 이러한 경우에 있어서도 그 지대의 자연적, 사회적 조건이 그 작물의 재배에 적합할 때에 비로소 주산단지의 조성이 성공을 거두게 되는 것이다. (중략)

Cyperus rotundus has been grown for a long time in korea to be used as medicinal crop. This study was conducted to survey the production status and economic analysis in chief producing area of Cyperus rotundus in Koryong, Korea. The Koryong area where was the major production area of Cyperus rotundus was composed of 0.6hectare cultivation size per farm household and the processes like cultivation, processing, shipping were formed unitedly. The most general management type was labor-extensive one which use the Nakdong river basin or idle land effectively. The cultivation area have been decreased gradually because the price was very low so that the income per hectare was just 3,880 thousand won and productivity per hectare was just 6,280kg. Thus, production condition was very inferior, it needs some self-help to encourage the production because it has some possibility as only regional special product.
