However, higher P_pp rates increased dry biomass, P uptake, and tuber yield, with no significant differences between 49 and 74 kg ha⁻¹ P rates. Liquid P applied at a rate of 12 kg ha⁻¹ of P during tuber initiation stage significantly increased potato total and marketable yield compared to no liquid P application in 2019.

With the multitude of cultivars and variable relative maturity, numerous studies have shown that nitrogen management in potatoes is a key to tuber yield and quality. Most potato growers tend to apply high amounts of nitrogen fertilizer while yield is not always consistent with the applied nitrogen fertilizer rates. Thus, potato cropping system specialists have been developing critical nitrogen dilution curves across different environments and for different potato cultivars with quite large variability in the equations. This review aims to inventory the developed critical nitrogen dilution curves for potatoes worldwide and analysis the discrepancies. A literature search was performed using online search engines for 6 months using keywords such as nitrogen dilution curve, critical nitrogen dilution curves of potatoes. Published results collection was done for the well-known peer reviewed journals. The critical N concentration (Nc) is defined as the minimum nitrogen concentration for achieving maximum aboveground biomass at any time during the crop growing season and it is represented by an allometric function, i.e. Nc = aW^−b where W is the total shoot biomass [Mg dry matter (DM) in ha ⁻¹], Nc is the total N concentration in shoot (g kg ⁻¹ DM), and a and b are estimated parameters. The parameter “a” of all monitored critical nitrogen dilution curves falls within the range [1.5, 7] of which 50% of the parameter “a” falls within the range of [5, 5.5] and the parameter “b” falls within the range [0.15, 0.60] with a large variation. The parameters “a” and “b” are impacted by the potato genotype, environment, and the management practices. Moreover, the estimation procedures of the parameters “a” and “b” were different and impacted the magnitude of these parameters. Based on some recent studies, we recommend the use of the Bayesian hierarchical method or the pooled Bayesian hierarchical method to develop a unique critical nitrogen dilution curve for potatoes that includes several genotypes, environment, and management practices for nitrogen fertilizer application rate optimization, system profitability and sustainability while reducing soil and water pollution by the nitrate leaching due to over fertilization and inappropriate split and timing of the nitrogen fertilizer application.</p></div>","PeriodicalId":7596,"journal":{"name":"American Journal of Potato Research","volume":"102 2","pages":"107 - 118"},"PeriodicalIF":1.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143877740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional insecticides generally showed more non-target effects, and responses were always stronger for arthropods from vacuum samples than pitfall samples.

In addition, two field trials examined seed size performance (28, 42, 56, 70, 84, and 98 g (1.0, 1.5, 2.0, 2.5, 3.0, 3.5 oz)) for Clearwater Russet, Ranger Russet, and Russet Burbank. Seed type performance (whole vs cut) was also assessed for Clearwater Russet. As seed size increased from 28 to 98 g for all varieties and seed types, early plant growth generally improved, average tuber weight decreased by 22%, and stem and tuber number per plant increased by 77% and 50%, respectively. Cut Clearwater Russet seed produced 7% higher yields and 5% more economic return than whole seed. Economic return peaked for Clearwater Russet with a seed weight of 56 g (2.0 oz). Economic return of Ranger Russet and Russet Burbank peaked when seed size was between 70–84 g (2.5 to 3.0 oz) for Russet Burbank and at 84 g (3.0 oz) for Ranger Russet.

In the U.S. Northwest Potato Variety Development Program (NWPVDP), L/W accounts for 13% of the overall postharvest score. Selections with L/W ≥ 1.8 are preferred for maximum raw-product recovery (≥ 7.6-cm-long fries). However, tuber shape often depends on production location. Our objectives were to (1) model the effects of production location on L/W using 26 years of historical data from the NWPVDP, and (2) quantify the variability in tuber shape phenotype of selected NWPVDP varieties across production locations (WA, ID, OR). A mixed linear model demonstrated that tuber L/W was strongly affected by location, year, and location-by-year interactions (40% of total variation), while variety and variety-by-location accounted for 43% of total variation. L/W of the 227-284-g tubers of twenty-two released varieties from the NWPVDP averaged 1.65, 1.70, and 1.92 for WA, OR, and ID, respectively, and ranged from a low of 1.51 and 1.53 (<i>cvs.</i> Payette Russet &amp; Palisade Russet) to a high of 2.06 and 2.12 (<i>cvs.</i> Ranger Russet &amp; Echo Russet) across locations. The round phenotype of Palisade was stable across locations, leading to consistently low fry recovery (84% FW). By contrast, Payette tubers were invariably round in WA and OR, but elongated when grown in ID. The elongated phenotypes of Echo and Ranger from all locations ensured maximum fry recovery (94 to 95% FW), despite the relatively high variation in L/W (9–13%) attributable to location. Collectively, our results suggest an opportunity for genetic selection of L/W that are stable across locations for market specific reductions in shape waste. Future work should focus on identifying key mechanisms which are impacted by production environment for improved stability of L/W.
