“…These values were within the normal range of potato yields for the area where the experiment was conducted [37]. Yield depended on the growth conditions, crop management, and soil N supply, coinciding with the results obtained by Zebarth et al [2].…”

“…The ONR, ne- cessary to predict MY, varied between growing seasons for each cultivar, with the values ranging from 150 to 250 kg•N•ha −1 . This response reflects the fact that the variation in soil N supply can often be as important as crop N demand in determining the optimal fertilizer N rate [2].…”

“…Fry color index is an important indicator of food product characteristics because it is the essential quality parameter that is evaluated by consumers even before the food is consumed [36]. The N fertilizer rate has an inconsistent effect on chip or fry color [2]. Chip color has been reported to be unaffected by the N fertilizer rate [13, 16, 37, 38].…”

Nitrogen (N) is an important factor that influences potato production; appropriate N fertilizer management can optimize tuber yield and quality and thus reduce the risk of environmental N losses. The present study aimed to evaluate the effects of different nitrogen (N) application rates (0, 75, 150, 225, 300, and 375 kg ha−1) on the total tuber yield, marketable yield, dry matter content, reducing sugar content, sucrose content of tuber, and fry color index of two potato cultivars (Kennebec and Shepody) in 2016 and 2017. N supply significantly affected tuber yield and processing quality, but these effects depended on the year and/or cultivar. The results indicated that low (75 kg ha−1) and medium-N application rates (150 or 225 kg ha−1) had a positive effect on tuber yield and processing quality; however, high-N application rates (300 and 375 kg ha−1) resulted in lower yield and poor quality. Total and marketable yields responded quadratically to N, and they were optimized at 150 kg ha −1 for Kennebec and 225 kg ha−1 for Shepody in both the years. The processing quality of tubers also responded quadratically with increasing N application rates. The optimal range of N application was approximately 145–185.83 kg ha−1 for Kennebec and approximately 93.44–288.67 kg ha−1 for Shepody according to the processing quality standards of French fried potatoes in China. To achieve the goals of high yield and high quality, N application rates should be 150 kg ha−1for Kennebec and 225 kg ha−1 for Shepody.

Nitrate leaching from potato (Solanum tuberosum L.) production is of great concern because of its potential effects on water resources. Suction lysimeters were used in combination with a one-dimensional flow model to quantify NO 3-N leaching under irrigated potato produced on sandy soils near Québec City, QC, Canada. The 3-yr (2010−2012) study compared a single application of polymercoated urea (PCU) and split-applied soluble N fertilizers (ammonium nitrate, AN; ammonium sulfate, AS) at three N rates (120, 200, and 280 kg N ha −1) in addition to an unfertilized control. Fertilizer N application increased total seasonal NO 3-N leaching. A single application of PCU increased total seasonal NO 3-N leaching in 2011 compared with AN and AS, which was attributed to a greater soil NO 3-N concentration under the PCU treatment in combination with increased rainfall during the tuber bulking phase (60−90 d after planting). Total seasonal NO 3-N leaching in 2012 was reduced with PCU and AS compared with AN, which was attributed to reduced soil NO 3-N concentrations between planting and hilling when rainfall was high. Regardless of the fertilizer N source, NO 3-N leaching was primarily driven by precipitation, as leaching occurred when elevated soil NO 3-N concentrations coincided with excess water in the soil. The results suggest that a single application of PCU is an effective strategy for reducing NO 3-N leaching in years when there is significant rainfall during the period between planting and hilling. 1 INTRODUCTION Potato (Solanum tuberosum L.) is an economically important crop in Canada. In 2017, approximately 138,339 hectares of potato was harvested, of which about 13% was in Quebec (Statistics Canada, 2019
