This presentation will help consultants, growers, and other practitioners manage nitrogen (N) for irrigated potato production in the upper Midwest. Of the essential elements required for potatoes, N is the one that often has the most important effects on tuber yield and quality. The topics addressed in this presentation include a brief review of potato N needs and the N cycle; N requirements in relation to specific potato growth stages; factors to consider when developing an N management plan; and potato responses to N from various research trials. From this presentation, the practitioner should learn how to make N rate and timing recommendations for optimal potato yield and quality.
