英文摘要	The potential for significant variability in potato (Solanum tuberosum L.) yield and quality caused by soil properties can be employed as a foundation for site-specific soil management. The current work investigated the relationship of soil properties, including the texture, moisture, and nitrate-nitrogen, with the variability of potato yield and quality on 28 ha center-pivot irrigated fields located in northwest China, where the soil was improved in 2014 by mixing Aeolian sandy soil with feldspathic sandstone. Geostatistic and correlation analyses were utilized to extract the relationships among soil properties and potato tuber properties. K-means clustering methods were utilized to establish critical sample points and soil factors for spatial variability of potato yield and quality. The spatial dependence of the potato tuber yield and quality varied from weak to strong, and most had unstable spatial structure considering the soil temporal variability, except reducing sugar content. More than 66% of the correlation coefficients between soil sand content and tuber variables were significant. The evaluation of the K-means clustering algorithms' effectiveness showed that circle minus v-All, PC-All, and texture had superior prediction results for tuber yield, dry matter content, and starch, respectively. N-All and soil texture datasets exhibited the best performance for reducing sugar content. Unsatisfactory prediction results were obtained for protein and VC. The results can be utilized to realize different objectives for in-field site-specific potato management.
