This experiment was carried out to elucidate the effect of row width and hill space on growth and yield in cynanchum wilfordii on experimental fields of chungbuk Provincial Rural Development Administration. Emergence date was May 25 and had no differences between planting density. Vine length was 219cm with row 40cm, 220cm, with 50cm and 225cm with 60cm, and in hill spaces, it was 225cm with hill space 10cm, 219cm with 15cm, and 218cm with 20cm. No. of leaves was same tendencies to vine length and was more increased as the hill space was narrower. Root length was longer about 0.9cm to 1.4cm as the hill space was wider, and no. of root had no difference between planting tensity. Yield was more increased row width was wider and was decreased hill space was wider. And the profitalble planting density was row width 50cm and hill space 10cm in the cultivation cynanchum wilfordii.
