Abstract

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, Dakota Pearl. In 2019, ND7799c-1 grown at 23 cm within-row spacing had similar marketable yield to Dakota Pearl. In 2020, ND7519-1 at all within-row spacings, and ND7799c-1 at 15 and 23 cm within-row spacing, yielded similarly to Dakota Pearl. Nitrogen rate did not affect yield or chipping quality in 2019 or 2020. The advanced selections had lower sucrose and glucose levels one month after harvest compared to Dakota Pearl in 2020. ND7799c-1 stored for 8 months, and ND7519-1 for 6 months, before chip quality declined. This research demonstrates the potential for ND7799c-1 and ND7519-1 to be successful chip processing cultivars for the Northern Plains.
