Nutrient use efficiency (NUE) is widely recognized as an important indicator to evaluate the availability (uptake, utilization and recovery) of mineral nutrients. Sorghum-sudangrass hybrid tends to increase in cultivation scale due to vigorous growth and higher yield. Therefore, the aim of this study was to provide the optimal NPK fertilization rates for sorghum-sudangrass hybrid based on nutrient use efficiency and yield. The fertilization rates of N, P₂O₅ or K₂O were divided into four levels; 0%, 50%, 100% and 200%. Biomass yield of sorghum-sudangrass hybrid at harvesting stage showed an increasing trend with fertilization levels but was not significantly within treatment groups. Uptake of N or K was significantly increase by fertilization levels of N or K₂O, whereas P uptake was similar in all P₂O₅ fertilization levels. NUE was significant in N treatments, whereas P- and K-use efficiency did not differ significantly among different fertilization rates. Consequently, this study suggests that the recommended rates of N (175 ㎏ ㏊<sup>-1</sup>), P₂O₅ (150 ㎏ ㏊<sup>-1</sup>), and K₂O (150 ㎏ ㏊<sup>-1</sup>) were optimal for ensuring biomass production and nutrient use efficiency in the sorghum-sudangrass hybrid.
