Abstract

The effect of applying special fertilizers on the yield and quality of sweet potato was studied. The results indicated that the yield of sweet potato increased by 14. 0% which reached the high significant level, the income increased by 23. 9%, the quality of sweet potato was improved by applying special fertilizer I and the content of soluble sugar , crude protein and amylum increased by 0. 85, 0. 25 and 3. 60 percentage respectively compared with those of the normalized fertilizer application. The effect on increasing yield and improving quality of sweet potato reached the high significant level compared with the tradictional fertilizer application. The content of soluble sugar, crude protein and amylum increased by 1. 76, 0. 41 and 2. 91 percentage point and the benefit increased by 13. 0% and 23. 9% respectively. The special fertilizer I showed significant effect on increasing yield , quality and efficiency of sweet potato.
