The object of this study conducted to investigate the effect of paddy-upland rotation cropping system on soil properties and crop productivity in newly reclaimed tidal land. Five types of paddyupland rotation cropping system were evaluated : Rice-Rice (RR) Rice-Maize (RM), Mize-Maize (MM), Rice-Soybean (RS), Soybean-Soybean (SS). The soil bulk density was the lowest RM treatment, and soil pH was a tendency to be lower in all treatments of the paddy-upland rotation cropping system. RM treatment showed a higher moisture content and lower Electrical conductivity than RR treatment. Results of maize productivity in paddy-upland rotation cropping system, Except for the stem diameter growth, RM treatment showed good growth and productivity than MM treatment. Soybean growth and yield increased in the rotated upland cultivation from rice-paddy field compared to the SS treatment. But, overall treatments indicated poor growth and yield. In this study, we offer the effects of paddyupland rotation cropping system on the soil properties and upland crop growth and yield, and also out results can be provide supporting basic data that introduced paddy-upland rotation in reclaimed tidal land.
