“…Moreover, Mozafar [71] reported that excessive nitrogen rates may have a variable effect on the ascorbic acid content of food plants such as potato. On the other hand, Boydston et al [72] did not observe statistical differences in the ascorbic acid content under different nitrogen rate levels, but also noticed a significant year effect indicating the variable environmental effect.

“…According to the literature, fertilization rates may affect antioxidant properties of colored-flesh potato tubers through the increase of polyphenols content such as chlorogenic acid and anthocyanins [16]. In contrast, Boydston et al [72] estimated the antioxidant capacity of two potato varieties without recording any significant differences for the different tested nitrogen rates. Moreover, Seijo-Rodríguez et al [73] evaluated the antioxidant activity and total phenols and flavonoids content in tubers of 35 potato varieties with varied skin and flesh color and reported a great variation in the tested parameters among the tested varieties, as well a strong correlation of antioxidant activities with polyphenols content.…”

Potato cultivation is quite demanding in inorganic nutrients and adequate fertilization is a key factor for maximizing yield and producing tubers of high quality. In the present study, a field experiment was carried out to evaluate the effect of various forms of fertilization on crop performance and the nutritional value and chemical composition of two potato varieties (cv. Spunta and cv. Kennebec). For this purpose, five different fertilizer treatments were applied namely: control (C), standard fertilizer (T1), standard fertilizer + zeolite (T2), manure (T3) and slow release nitrogen fertilizer (T4). According to the results, it was observed that slow release treatment (T4) achieved the highest yield for both varieties, while the control treatment presented significantly lower yield compared to the studied fertilization regimes. The dry matter of leaves and shoots was higher in T1 treatment for cv. Kennebec and in T2 and T4 treatments for cv. Spunta, whereas the control treatment presented the highest dry matter content in tubers for cv. Kennebec and T2 and T3 treatments for cv. Spunta. A significant effect of the fertilization regime was also observed on the nutritional value of tubers and more specifically the protein, ash and fat content was increased by treatments T1 and T4, while carbohydrate content was also increased by T3 and T4 treatments for both varieties. Similarly, the total sugars, organic acids, β-carotene and lycopene content was increased in T3 treatment for the Spunta variety, while the antioxidant capacity showed a varied response depending on the fertilizer regime and the tested variety. In conclusion, the fertilization regime has a significant effect not only on the tuber yield but also on the quality of the final product and should be considered as an effective tool to increase the added value of potato crop.

“…Quality traits, such as skin color and skin set, drive consumer preference in this market class. We expect these traits may be affected by N because excess N delays vine maturity (Boydston, Navarre, Collins, & Chaves‐Cordoba, 2017), and vine maturity determines skin set (Wiltshire, Milne, & Peters, 2005). Consequently, we examined skin color and skin set in addition to yield, NUE, NUtE, NUpE, and root mass.…”

Potato (Solanum tuberosum L.) production on sandy soils requires added N. Only 40-60% of the applied N is acquired by the crop. Increased N use efficiency (NUE) and its components, N utilization efficiency (NUtE) and N uptake efficiency (NUpE), could reduce fertilizer rates and environmental losses. We compared N efficiency in fresh-market red potato varieties, in terms of yield and quality traits, and examined potential mechanisms for that efficiency including uptake, utilization, and increased root growth. We grew selections from a red potato breeding population and commercial varieties under two N rates: 101 and 202 kg N ha −1. We compared NUE, NUpE, and NUtE in low and high N. We compared root phenotypes at tuber initiation and yield and skin quality metrics at harvest. Values for NUtE correlated with NUE and yield in low N and NUpE correlated with NUE and yield in high N. Low-N conditions produced smaller tubers, while high N resulted primarily in medium tubers. Nitrogen did not affect skinning and redness but low N did result in slightly lighter skin color. Total root mass 45 d after planting (DAP) correlated with final yield and NUE but did not correlate with measures of N uptake across treatments. Larger roots correlated with NUpE only in the high-N treatment. Selection under low N may reveal NUE and expose more stable representations of the genetic components of skin quality phenotypes. While skinning and skin color were more variable among varieties in low N, within variety they exhibited year-to-year consistency. 1 INTRODUCTION Potato (Solanum tuberosum L.) is the third most important food crop in the world (FAO, 2018). As the global population increases (United Nations, 2015), potato production must

“…Previous studies report similar findings where the presence of a relationship between N and yield depends on the level of N being compared. Boydston et al [40] reported no N rate effect on tuber skinning, size distribution, and weight loss in table stock potatoes. Makani et al [58] also reported a significant yield increase for table stock potatoes when N rate was increased from 0 to 224 kg/ha.…”

“…In processing potatoes, N influences specific gravity, sugar content, tuber size, hollow heart, and scab severity [38,39].

Genotype and Variable Nitrogen Effects on Tuber Yield and Quality for Red Fresh Market Potatoes in Minnesota

et al. 2021

View full text Add to dashboard Cite

Potato (Solanum tuberosum) production generally requires added nitrogen (N), which is costly and potentially environmentally damaging. One path to limiting N application is breeding N efficient potatoes. Effective use of nitrogen, across crops, is typically characterized in terms of yield. However, tuber quality characteristics affect potato marketability, especially for red fresh market potatoes. While optimal N rates maximize yield, the genotype-specific effect of N on tuber quality traits is unclear. In order to highlight quality traits effected by N, identify germplasm with lower N requirements, and determine optimal N rates for red-skinned clones, we conducted a variable N rate experiment over two years in Minnesota. Eight red fresh market genotypes were grown in RCB factorial design with five nitrogen application rates ranging from 0 to 81.6 kg/ha. Best linear unbiased estimates were calculated for yield, skin color, skin set, and tuber shape. The models for yield and quality traits included significant genotype by N rate interaction effects, suggesting that there is variation in the way clones respond to N. Established varieties were more responsive to added N than breeding lines. Similarly, established varieties tended to produce more oblong tubers under higher N conditions, while the breeding lines remained round. Color traits also responded to N in a genotype-specific way, while the interaction effect for other traits depended on unmeasured environmental factors. No clone exhibited increased yield above the 54.4 kg/ha rate. Our results suggest that the 81.6 kg/ha rate produced less favorable phenotypes for all traits.
