The early Joseon Dynasty is very important period of studying about Korean history of ceramics because various kinds of porcelain were produced like celadon, brown porcelain, white porcelain, inlaid white porcelain, blue porcelain etc, $\ulcorner$sejongsilrok$\lrcorner$ $\ulcorner$Jiriji$\lrcorner$ was published and Saongwon established its branch. Moreover, there also had a sudden political change to Joseon Dynasty, so ceramic industry in Gangjin was closed and artisans in Gangjin scattered to find safer place. One of these place was Imiwueri and Chuhyunri, Joongmohyun in Sangju.(the name of the place in that times, now Modongmyun) Also, Sangju in Gyeongsangbuk-Do is one of the places where can get materials for producing white porcelain, so artisans in Gangjin could migrate to the place during change of regime to Joseon Dynasty which based on Sung Confucianism. In $\ulcorner$Tejongsilrok$\lrcorner$, it mentioned specific areas like Joongmo, Hwaryeong in Sangju, Gyeongsang-Do and we can find out about situations of ceramic production in the early 15 centuries with producing dishes for a Royal family. $\ulcorner$Sejongsilrok$\lrcorner$ $\ulcorner$Jiriji$\lrcorner$ mentioned Imiwueri and Chuhyunri and Sangju produced the half of porcelains. In $\ulcorner$Gyeongsangdojiriji$\lrcorner$, Sangju takes charge of 8 spots which is one third of ceramic production. $\ulcorner$Gyeongsangdojiriji$\lrcorner$ and $\ulcorner$Sejongsilrok$\lrcorner$ $\ulcorner$Jiriji$\lrcorner$ were published with same goals at the same year. In $\ulcorner$Gyeongsangdosokchanjiriji$\lrcorner$, there was deleted nine spots which included high, middle, low level compared with $\ulcorner$Seiongsilrok$\lrcorner$ $\ulcorner$Jiriji$\lrcorner$, and in $\ulcorner$Donggukyeojiseungram$\lrcorner$ there was entirely deleted the locations of porcelain spots and potteries.

General procedures of seed preparation as conventional guide had been established in China before most of Korean literature documented them. ‘Chwijongbeob’ (method of seed select) was to select good quality of seeds and to discard the rest. In ‘Seonjongbeob’ (method of seed grading) although China employed only ‘Sooseonbeob’ (method of seed select with water), but seeds were selected in order of selection of seeds by winds, selection of seeds by sieve and selection of seed with water in Korea. As compared with the recent techniques, those methods were perfect techniques for selection of good quality seeds of rice, except for method of seed selection by salt water was developed. The method for measurement of seed moisture, and for measurement of melted snow, spoiled urine and extracted juice by boiling water with the bone of livestock were originated from ancient China. The farming books in Korea were more or less followed the above methods. However, these techniques were complicated and impractical interms of validity and rationality. Also, it is judged that these tchniques are more appropriate in dry areas and alkaline soil of China rather than in Korean conditions. The plowing is a work to begin farming, and is operated for air ventilation between atmosphere and earth. Also, this techniques was adopted in the farming books from the early to the late Chosun dynasty without changes. Fields were deep-plowed in the first, in fall (or in spring) and for cultivation, and were shallow -plowed in the second, in spring (or in summer) and in intertillage. The former was for water reserve and land preparation, and the later was for weed control with intertillage. However, plowing in fall which was different from fallowing in dry areas, was recommended in Korea (Jikseol). but was not practiced in Sejongsilrok. This was changed with time, and plowing for cultivation in Korea was interrelated with use of green manure crops, method of plowing of upseting plough, method of manure practice and sometimes dry plowing. In addition, until the 15th century method of using a kind of plowing-tool made of log as farm tools was created to support reclamation for enlargement of farm land in mountaineous and coastal areas. For desolate farm lands by many internal and external disturbances, one tried to recover yield ability by increasing labor productivity from the 17th or 18th century. To do this, ‘Banjongbeob’ (culture method by upset plowing weed control) and ‘Hwanubeob’(culture method by firing weed control) which were cultural methods of ancient China were readapoted but the results were not clearly informed. Also, the reality of those was reexamined in the end of the Chosun dynasty.
