Abstract
This study was conducted to increase the productivity and quality of C. auriculatum Royle ex Wight according to the various ridge height. The higher ridge height increased the vine length, leaf length, leaf width, leaf number, chlorophyll content, and leaf dry weight; however, the lower ridge height increased the stem diameter and branch numbers. The tuber number and length was increased at less than 20cm of ridge height, but the overall growth was retarded in the treatment of over 20cm ridge height. The tuber diameter was also thicker in the lower ridge. The rootlet ratio among the non-commercial tuber was increased in the 20cm and 30 cm ridge, and the decayed tuber ratio was increased in the lower ridge. The yield of tuber has increased with 3% and 11% in the 20cm and 30cm ridge height compared to 10cm ridge(515kg/10a).
