This study was conducted to establish the environment-friendly cropping system of soybean in paddy field with different soil textures. When the soybean was cultivated in paddy fields, growth responses of testing cultivars varied depending on soil texture and cultivation method. Growth responses of soybean in sandy loam tended to be better than those in clay, however the effect of high ridged cultivation was distinguished in clay loam. Especially, formation of rhizome nodule was significantly different depending on soils ; more numerous rhizome nodules were formed in sandy loam compared to that in clay. Plant heights of Taekwangkong and Eunhakong were highest in clay and sandy loam, respectively, while the number of pods and branches of Eunhakong were most in both soils. In clay paddy field, growth responses of Eunhakong were best among the testing cultivars, however high ridged cultivation was more appropriate to the cultivar compared to level row cultivation regardless of soils. Taekwangkong showed the highest leaf area indexes during whole growth stages. Leaf development of Daewonkong was suppressed in clay at early growth stage, while it significantly increased as growth stages progressed. Most retard leaf development was observed in early maturity cultivar, Hwaseongputkong, since it seemed to be seriously damaged by excessmoisture injury in both soils. Comparing the dry weight of top plants and roots, plant growth was more affected by soil texture than cultivation methods at early vegetative growth stage, via verses at R2 or R5 stages. In yield characters and yields at R8 maturity stage, pods number of Eunhakong was significantly higher than those of Daewonkong and Taekwangkong estimating to 107 and 124 in clay and sandy loam, respectively. The ratio of ripened seeds was highest in sandy loam in combination with high ridged cultivation, while the lowest in clay with level row. The yields of Deawonkong and Eunhakong were higher compared to other testing cultivars ranged from 182~286㎏/ha depending on soils and cultivation methods. In results, growth responses and yields of testing cultivars tended to be higher in sandy loam in combination with high ridge compared to clay with level row.
