Abstract: This paper reports the experimental results of 8 leaf-vegetable sweet potato in Hainan Province, China. The results as below: the fresh tender stem-leaf yield of Guangshucai 2 was 24.3t/hm², best taste, rich nutrition and widen tolerance. The fresh tender stem-leaf yield of Fucaishu 1 was 18.7t/hm²，better taste and rich nutrition, moreover, its fresh root and dry root yield were 18.6t/hm² and 4.2t/hm², respectively, best taste and rich nutrition for root-eating. The fresh tender stem-leaf yield of Fushu 7-6 was 12.6t/hm² owing to weak adaptation, but it possessed excellent taste and nutrition. Suggestion: Guangshucai 2 is adapt to extensive cultivation, Fucaishu 1 is good for leaf-vegetable also root-eating, Fushu 7-6 can harvest high yield and income under the better management condition according to some other experiment.
