The data describes yield and quality traits for sweetpotato cultivated under drought and irrigated conditions in Kuru, Plateau state, Nigeria The experiment evaluated the effect of drought on the yield and proximate composition of fourteen accessions of sweet potato grown in Kuru, Nigeria. The accessions were laid out in the field using the randomised complete block design. Sweetpotato plants were subjected to drought-stress at 103 DAP (days after planting) until harvest at 150 DAP. Fresh tuber ranged from 2.14 t ha-1 to 21.18 t ha-1 but was reduced by as high as 68% in drought-stressed plants. Total storage root yield, crude protein, carbohydrate and dry matter content (%) were higher in the control than in the drought-stressed plants.本数据集记录了尼日利亚高原州库鲁地区于干旱与灌溉栽培条件下甘薯（sweetpotato）的产量与品质性状。本试验以尼日利亚库鲁地区种植的14份甘薯种质系为材料，评估了干旱胁迫对其产量及常规营养组分的影响。供试种质系采用随机完全区组设计（randomised complete block design）进行田间布局。甘薯植株于播种后103天（DAP，days after planting）开始遭受干旱胁迫，直至播种后150天收获。块根鲜产量介于2.14吨·公顷⁻¹至21.18吨·公顷⁻¹之间，但干旱胁迫处理组植株的块根鲜产量最高可降低68%。对照组的总贮藏根产量、粗蛋白、碳水化合物及干物质含量（%）均高于干旱胁迫处理组植株。
