Abstract: A single factor randomized block experiment design was used to explore the suitable fertilization level of cassava variety GR5. The results showed that the plant height of cassava GR5 was significantly increased(P<0.01),and the internode spacing of stem and leaf number were significantly increased(P<0.05),and the yield and the starch content of fresh tuber root were significantly increased(P<0.01)under the ratio of 100-50-0 “NPK”treatment;100-50-0 was the best fertilization treatment for GR5; GR5 was a barren-tolerant variety that required less potassium fertilizer.

Key words: cassava, GR5, ratio of “NPK”
