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,...

Demand for tablestock potatoes with a smaller tuber size profile is increasing. A study assessing the effect of narrow row width on fresh market yield and economic value was conducted in 2022 and 2023, near Becker, MN, and Inkster, ND, using a split-plot design with factorial arrangement of treatments. Five row widths (71, 76, 81, 86, and 91 cm as the standard industry row width) and four cultivars (Agata, Musica, Modoc, and R...

Tablestock growers must produce high yields of optimally sized tubers to maximize market opportunities and economic returns. The effects of row width and seed spacing on tuber yield and profitability for Red Norland were evaluated in 2022 and 2023 near Becker, MN, using a split-plot factorial arrangement of treatments. Five row widths (71, 76, 81, 86, and 91 cm) and three seed spacings (20, 25, and 30 cm) were assessed. The 91...

Adoption of new cultivars is challenging for commercial growers. To understand the best nitrogen fertilization rate (90, 134, 179, and 224 kg N ha -1 ) and within-row spacing (15, 23 and 31 cm) for two potential potato cultivar releases from North Dakota State University, a study was carried out in 2019 and 2020 in North Dakota. The advanced chipping selections ND7799c-1 and ND7519-1 were compared to a chip industry standard,...

Summary Perylenequinones are a family of structurally related polyketide fungal toxins with nearly universal toxicity. These photosensitizing compounds absorb light energy which enables them to generate reactive oxygen species that damage host cells. This potent mechanism serves as an effective weapon for plant pathogens in disease or niche establishment. The sugar beet pathogen Cercospora beticola secretes the perylenequinone...
