Abstract
The row width for chip processing potato cultivation in the Upper Midwest ranges from 91 to 96 cm, with 91 cm as the industry standard in Minnesota and North Dakota. A smaller tuber-size profile is desired for packaging and improved production. A study evaluated the effects of narrow row width on tuber yield and profitability. A split-plot design with a factorial arrangement of treatments evaluated five row-widths (71, 76, 81, 86, and 91 cm) and four cultivars (Dakota Pearl, Lady Liberty, Manistee, and Snowden) in 2022 and 2023, near Becker, MN, and Inkster, ND. Row widths of 71 and 76 cm increased marketable yield by 11 to 14% compared to 91 cm. Widths of 71, 76, and 86 cm increased profits by $1,392, $1,162, and $616 ha −1 , respectively, compared to the standard. Results demonstrate that producers can adopt narrower row widths to maximize efficiency and profitability in the Upper Midwest.
