Chinese yam (Dioscorea Opposita Thanb) has been cultivated as medicinal crop and food. The experiment was carried out to determine the effect of tuber head origin and fertilizer application method on its agronomic characters of shoot and root tuber to get some imformation on its cultivation. The tuber head cultivated were cut from normal or branched root tuber. 37-28-32-2000 : N-P-K-Humus(Kg/10a) by dispersal but 30% N reduction of Con(RN) or strip application on the two-side of hill(SRN), were applied but N and K were given by the above method with the rate of 40% in March, 30% in June and 30% in July. Agronomic characteristics related to shoot and root tuber were measured and their relationship was analyzed. Tuber head origin had no effect on emergence rate, vine length, branch and node of vine, while emergence date of the tuber head from the normal root which showed the greatest emergence rate, vine length and node in Con treatment was earlier than the others. The tuber head from the normal root, furthermore, had greater length and diameter of root tuber harvested from the field and fresh weight per plant of per 10a compared to the tuber head from the branched root, whereas in both the normal and the branched tuber head RN had the worst result in the characters related to tuber yield except tuber diameter. The tuber head from the normal root produced heavier root tuber than that from the branched tuber and SRN had the best economic yield among the application methods, which resulted from production of less branched root tubers and their rate. In both the normal and the branched tuber head, moreover, yield per plant and economic yield were positively correlated to tuber length but negatively done to number. of branch of vine.
