Interpretive Summary:

Technical Abstract: Potato responses to different rates of pre-plant and in-season N management are evaluated under reduced and conventional tillage under center pivot irrigation. Tuber yield, tuber size distribution, and tuber specific gravity were largely similar across different tillage and N management practices. Potato was rotated with two years of sweet corn in this study. Frequency of in-season N application from 5 to 10 at a given N rate had no significant affects on tuber yield or quality. Reduced tillage offers savings in energy and labor costs, therefore, net return is expected to be greater under reduced tillage than that with conventional tillage despite similar yields and tuber quality under both treatments.
