Generally, no significant differences in agronomic characters and yield components of sweet potato were observed using either the traditional methods or the recommended practice of planting. Varying the number of cutting per hill significantly influenced only the fresh vine weight of Kaimay, BNAS-51 and Samar Big Yellow sweet potato varieties. Plants that developed from one cutting per hill produced heavier herbage than the other treatments. Root yield was likewise not markedly affected by the number of cuttings per hill although the varieties, Kaimay obtained the highest value in yield and nearly all yield components.
