Abstract: The influence of different combination of organic and inorganic fertilizers was analyzed on the yield of sweet potato tuber and shoot in fresh. The results showed that combined application of organic and inorganic fertilizers was an important way to improve the production. The recommended fertilization combination rate was organic fertilizer 15 000 kg per hectare (rotten cow dung), N214.5 kg per hectare, P90 kg per hectare and K150 kg per hectare. The yield of fresh sweet potato tuber and shoot would reach 60 202.5 and 57 355.5 kg/hm2, respectively.
