In Korea, the largest agricultural lands are paddy fields which have poor infiltration and drainage properties. Recently, Korean government pursuits cultivating upland crops in paddy fields to reduce overproduced rice in Korea. In order to succeed this policy, it is critical to understand topographic information of paddy fields and its effects on upland crops cultivating in paddy field soils. The objectives of this study were characterizing growth properties of soybean and adzuki bean from paddy fields with three soil topographic features and soil water effects which were induced by topographic features on sesame and perilla. The crops were planted in paddy fields located in Miryang, Gyeongnam with different topographies; mountain foot slope, local valley and alluvial plain. Soil water contents and groundwater levels were measured every hour during growing season. The paddy field of mountain foot slope was significantly effective to alleviate wet injury for soybean and adzuki bean in paddy fields. The paddy field of mountain foot slope decreased average soil water content and groundwater level during cultivation. Stress day index (SDI) from the alluvial plain paddy field had the greatest values from both crops and the smallest from ones of mountain foot slope. This result meant that soybean and adzuki bean had the smallest stress of soil water from the paddy field of mountain foot slope and the greatest from one of alluvial plain. It is important to consider topography of paddy fields to reduction of wet injury and to increase in yields.
