The interspecific estimation for tolerance capacities of upland crop species to excessive soil water stress in paddy field is significant in agricultural practices. Most of upland crops can be damaged by either excessive soil water or capillary rise of the water table during rainy season in paddy fields. The major objective of this study was to evaluate water stress of upland crops under different drainage classes in converted paddy field. This experiment was carried out in poorly drained soil (PDS) and imperfectly drained soil (IDS) of alluvial sloping area located at Toero-ri, Bubuk-myeon, Miryang-si, Gyeongsangnam-do. The soil was Gagog series, which was a member of the fine silty, mixed, nonacid, mesic family of Aeric Endoaquepts (Low Humic-Gley soils). Two drainage methods, namely under Open ditch drainage methods (ODM) and, Closed pipe drainage methods (PDM) were installed within 1-m position at the lower edge of the upper paddy fields. The results showed that sum of excess water days (SWD 30 ), which was used to represent the moisture stress index, was 42 days (the lowest) in the PDM compared with 110 days in the ODM. Most of upland crops were more susceptible to excessive soil water during panicle initial stage on more PDS than on IDS. Yield of upland crops in the PDM was continuously increased by the rate of 15.1% on sorghum, 15.4% foxtail millet, 53.6% proso millet, 49.6% soybean and 47.9% adzuki bean as compared in the ODM. The capacity for tolerance by excessive soil water based on yield of each upland crop in the poorly drained sloping paddy fields was the order of sorghum, soybean, foxtail millet, proso millet and adzuki bean. Therefore, Sorghum is relatively tolerant to excessive soil water conditions and, may be grown successfully in converted paddy field.

In South Korea, the area of agricultural land has steadily decreased and the overall food self-sufficiency rates have consistently dropped with a decrease in farm population since 2000. This study aimed to evaluate water requirements of crops soybean, sorghum, and sesame using lysimeter. Using the lysimeter with different groundwater levels, 20 cm and 40 cm, and different types of soils, sandy loam and clay loam, the evapotranspiration for crops was measured to determine the water requirement and the water use efficiency. The results showed that the maximum evapotranspiration of soybean and sesame was at the blooming stage, and that of sorghum was at the panicle formation stage. In water use efficiency, the optimal soil texture (groundwater level) for soybean was clay loam (40 cm), for sorghum was sandy loam (20 cm), and for sesame was sandy loam (40 cm). The water requirement of soybean and sesame was lowest at sandy loam (40 cm), while sorghum had the lowest at sandy loam (20 cm). The 100-kernel weight of soybean was found to be higher under the groundwater level 40 cm than 20 cm regardless of soil types, and 1,000-kernel weight of sorghum and sesame was found to be the highest under the sandy loam (40 cm). In consideration of these results, sandy loam (40 cm) was more suitable for cultivating soybean and sesame, and so was sandy loam (20 cm) for sorghum. The results of this study are expected to provide useful data for the development of an irrigation system which is possible to set the groundwater level as desired.

Double cropping system including paddy field soybean is widely adopted nationwide, due to rise in market price and its higher income than paddy field rice. Sowing date of soybean as a second crop is being delayed depending on first crop's growth period and harvesting time. Due to the increased temperature in October and delayed first frost date, soybean could be harvested without frost damage even in late-plating. Therefore, selection of soybean cultivar which is appropriate for this environment is very important. The effect of sowing date and genotype of soybean on growth and yield was investigated for three planting dates (June 20, July 5, and July 20) with ten cultivars developed for soy-pate production, to figure out plant development and yield pattern in delayed planting. As planting date is delayed, plant height and pod number was decreased and this pattern was more clearly detected in mid-late maturity cultivars. Hundred-seed weight did not show significant changes even in late planting, due to compensations between yield components. Yield reduction of July 20 in contrast to that of June 20 showed that Nampung (9.6%) showed the least yield decline. Maximum yield was achieved from Daepung, Taekwang, and Uram among other soybean cultivars in late planting. Shortening of growth period was strongly detected in reproductive stage while length of vegetative stage was regularly maintained in both early and mid-late maturity cultivars.
