This paper is studied in order to examine eight provinces as Agricultural zone in the early Chosun-Dynasty. The research method of this study depends on discriminant analysis. The research data is obtained from geography of Sejong sillok. In this approach, we believe the possibility of more scientific analysis of agricultural zone. So all cross-sectional data of this period were analysed by means of the discriminant analysis method. In the discriminant analysis of the eight provinces, 54.6% of the country were discriminated. In the territorial map, Kyongsang and Cholla were crossly adjoined and Chungcheong was located in the middle of them. While, Kyonggky and Hwanghae were adjoined in the center, and Pyongan and Hamgil were crossly adjoined, too. And Kangwon was located in the middle of them. Consequently their regional distribution varied widely and the agriculture of this period had considerable regional gaps.
