To identify the limited and adaptable sowing date and select the double cropping system, two different cropping systems such as potato (Sumi, Chubaek) - maize (Ilmichal, Yanganok) and maize (Ilmichal, Yanganok) - potato (Chubaek) were conducted in paddy and upland field condition. We observed and co

maize at this study sites. The GDD was calculated from sowing (May 1) to harvesting (Sep. 30). The average GDD of this region between 2010 and 2015 was 1323.0℃ day (595.3-1838.9). The spatial distribution of GDD showed a similar pattern during the different years surveyed. Double cropping for maize

maize through continuous twice cropping was 4.05% of total soil P in average, and the uptake in the second cropping was twice as much as that of the first cropping. 8. Three determination methods, i.e. Soltanpour-, Double lactate-, and Bray No. 1-method seemed to be more suitable than Lancaster met

Determination of the late marginal heading date (LMHD), which would allow estimation of the late marginal seeding date and the late marginal transplanting date, would help identification of potential double cropping areas and, as a result, establishment of cropping systems. The objective of this stu

BACKGROUND: During the off-season, the cultivation of Chinese cabbage and water dropwort is often used to desalinize plastic film house soils. The objective of this study was to verify the effect of double-cropping systems on the salt removal in oriental melon cultivated plastic film house soils.MET

double-cropping is effective in reducing nematode populations in soils. METHODS AND RESULTS: Nematode population in plastic film house soil was measured during oriental melon cultivation from April to July in short term crop rotation systems of oriental melon. Double-cropping of chinese cabbage in o

double cropping was specialized. But Byoengjak(竝作) system was distributed in the regions where upland crops are specialized and ratio of paddy field is comparatively low. Especially new types were emerged where ratio of paddy field was very low. These show that increase of productivity of land di

double crops a year and triple cropping for two years. The system of intercrop was promoted which would increase the degree of intensity in the field. The policy toward mixture cropping method fell into confusion by allowing some regions to practice and prohibiting in other districts. The practice o
