Research was implemented in Tuyen Quang, Nghe An and Thua Thieu Hue on only one cassava variety HI2004- 28 with 5 fertilizer levels compared to the control of non-fertilizer. The research results showed that: Different fertilizer levels had significant differences to cassava yield. Fertilizer combination of 15 tons manure + 90 kg N + 40kg P205 + 80 kg K2O/ha had the highest yield 4.35 tons/ha, higher than the control from 1.53 to 2.4 tons/ha and had higher net interest than level of local people (significance level of 95%).
