“…This part of the study discusses the common opinion regarding tuber yield response to water and nutrient supply to potato (Cambouris et al., 2016; Tan et al., 2016). The tuber yield obtained was significantly governed by two factors, interacting with each other.…”

Potato (Solanum tuberosum L.) tuber sink strength is determined by the maximum nitrogen concentration (N cmax ) in the tuber within the growing season. This hypothesis was verified based on data from two seasons with contrasting weather conditions, that is, the wet 2007 and the dry 2008. A field experiment, including four levels of nutrients: absolute control (AC), NP, NPK, and NPKMgS, was the basis of the hypothesis evaluation. Vines and tubers were collected periodically at 10-11 d intervals in 10, and nine consecutive samplings, respectively. Tuber yield growth was described by the linear and polynomial functions under favorable and unfavorable growth conditions, respectively. The polynomial functions indicated lower tuber yields (+20 t ha-1 for NPK vs. NP in 2007). The N cmax of the growing tuber is the key yield driver, defining the tuber sink capacity. As compared to the in-season variability in N a (N accumulated in vines-source capacity), the N cmax was a conservative trait, up-regulating the source activity. The narrowed N/P from 5.9 to 2.1, but from 4.6 to 1.9 and for N/Mg from 26 to 12, but from 22 to 14, respectively in 2007 and 2008, increased the steepness of the N c during its descending course. The tuber sink capacity can be fulfilled, provided there is a good supply of K during potato bulking. It can be concluded that the higher the N cmax , the higher the potato requirement for K. Any factor lowering the N cmax simultaneously decreases the potato requirement for K, subsequently leading to yield losses.

“…The TY obtained in NB and in QC was above that obtained in NB by Snowdon, Zebarth, Burton, Goyer, and Rochette (2013; 30.2 Mg ha −1 ) and in QC by Cambouris et al. (2016; 16.3–38.3 Mg ha −1 ) for Russet Burbank variety. In PEI, potato yield was in the range of those reported by Nyiraneza, Peters, Rodd, Grimmett, and Jiang (2015) for Shepody variety (20–27 Mg ha −1 ).…”

In acidic soils with high phosphorus (P) fixing capacity, P application at levels higher than crop requirements is common in crops with high P demands such as potato (Solanum tuberosum L.), which could lead to eutrophication. Recycled sources of P fertilizer, such as struvite, can be efficient in meeting crop P demands while minimizing P losses. The objective of this study-conducted in four provinces over 3 yr (2016-2018, with 12 sites in total) in Eastern Canada-was to assess potato response to P fertilizer as triple superphosphate (TSP) or a mixture of TSP with struvite. Eight P treatments were applied with five increasing P rates as TSP (0, 26, 52, 79, and 105 kg P ha −1 ) and three treatments as a mixture of TSP and struvite (25, 50, and 75% (w/w) struvite) at a rate of 79 kg P ha −1 . Phosphorus availability indices measured multiple times over the growing season were composed of Mehlich-3 extracted P (P M3 ), soil P adsorbed on anion exchange membranes (P AEMs ), and petiole P-PO 4 (P petiole ) concentrations. There was a potato yield response to P inputs at all sites, with the control treatment showing lower potato yield at all sites. Potato yield, P petiole , P M3 , and P AEMs were comparable between 100% TSP and TSP+struvite at the same rate, except at one site where struvite at a higher proportion depressed yield and was associated with lower P uptake. Overall, the use of struvite could be a sustainable mean to address long-term globally P scarcity.

“…All sites were fertilized with P, K, and Mg at rates recommended in each region from the soil analysis. Information on the soil available P and K contents along with the rates of P, K, and Mg fertilizers can be found in Cambouris et al (2016) for the Québec site and Nyiraneza et al (2015) for the Charlottetown site. We assumed that P, K, and Mg were not limiting potato growth and yield at any of the sites.…”

“…The plant N concentration was determined using the dry combustion method on an Elementar analyzer (Vario Max, Elementar Analyzer). More details about site description and sampling protocol are available in Morier et al (2015) and Cambouris et al (2016). All data from 2012 were used for model calibration, while data from 2010 and 2011 were used for model performance evaluation.…”

Simulating Potato Growth and Nitrogen Uptake in Eastern Canada with the STICS Model

The ability of process‐based soil–crop models to simulate potato (Solanum tuberosum L.) yield and N uptake for a range of N fertilization under the conditions of eastern Canada has never been tested. Our objectives were (i) to calibrate and evaluate the performance of the STICS model for the Shepody and Russet Burbank cultivars with cultivar‐specific critical N concentration dilution curves, and (ii) to quantify the gain in model performance with cultivar‐specific N concentration curves rather than a generic curve. Data sets including measurements of leaf area index (LAI), total and tuber biomass, and total and tuber N uptake for several N rates (0–280 kg N ha−1) collected at Charlottetown, PE; Fredericton, NB; and Québec, QC, Canada were used. Calibration was done with one data set from Charlottetown for Shepody and one data set from Québec for Russet Burbank, while all the other data sets were used to evaluate model performance. Following calibration, the STICS model generally performed well, with a normalized root mean square error (NRMSE) < 30% and a normalized mean error (NME) ranging from –8% to 23%, for LAI and biomass. Model performance was slightly worse for total and tuber N uptake, although cultivar‐specific N concentration curves for Shepody and Russet Burbank improved model performance compared with a generic curve with a lower NRMSE (18–50% vs. 21–63%) and NME (–9 to 23% vs. –14 to 23%). Cultivar‐specific critical N concentration curves should therefore be used for assessing the N budget of potato cropping systems.Core Ideas The STICS soil–crop model was calibrated and evaluated for two potato cultivars. Calibrated and evaluated variables were LAI, total and tuber biomass, and total and tuber N uptake. Cultivar‐specific critical N concentration curves are recommended for N budget assessment.
