A split-plot study was conducted to evaluate the yield response of ‘Whatley-Loretan’ sweetpotato when planted in single and double rows at four planting dates (March, April, May, and June) in a Wiregrass Tunnel House located at S&B Farm in Eufaula, Alabama. The main plots consisted of planting dates, sub-plots single, and double rows, with each treatment combination, replicated three times. The results showed a significant linear and quadratic effect for US#1 grade of sweetpotato and total marketable yields. Yields were highest at the first and second planting dates and declined at the two later planting dates. Single vs. double row planting significantly affected canner grade of sweetpotatoes, while the other grades were unaffected.
