“…The field trial was conducted at the University of Wisconsin Hancock Agricultural Research Station (UW HARS) in Hancock, WI (latitude: 44°12.1413; longitude: 89°53.6840; 328 m asl) in 2020 and 2021. The soil texture was a Plainfield loamy fine sand (mixed, mesic Typic Udipsamment) (Crosby & Wang, 2021; Yuan et al., 2017). The soil organic matter content was lower than 1% in both years, as it consists of excessively drained coarse sand.…”

There is a lack of nitrogen response research on dark red kidney beans (Phaseolus vulgaris L.). This is of particular importance as most cultivars form nodules and are commonly grown on sandy soil. The objectives of this study were to determine the effects of nitrogen rates and irrigation amounts on leaf area index, white mold occurrence, yield, and N uptake of dark red kidney beans. The study occurred at the University of Wisconsin Hancock Agricultural Research Station over two growing seasons (2020 and 2021), across four N rates, three irrigation levels, and five cultivars. Preceding crop for each study year was potato and field corn, respectively. More heavy rainfall events that may lead to leaching were observed in 2021. Neither irrigation effect nor general cultivar difference was observed on bean yield, disease resistance, and nitrogen use across the 2 years. Bean yield was significantly influenced by N rates across the five cultivars in 2020 but not in 2021, with 56 kg ha −1 more total N uptake at the lowest N rate in 2021. This highlights large site-year influences on N supply from fixation. Furthermore, although greater N application did lead to greater yield in 1 year, it was also associated with greater white mold disease pressure and lower partial factor productivity (PFP). Thus, there is economic risk in N application to dark red kidney beans on irrigated sandy soil from reduced quality (mold damage) and lower N use efficiency (indicated by lower PFP), although site-year effects remain unknown.

“…Al-Omran et al [49] also reported that the partial root-zone drying with 75% ETc did not result in significant yield loss as compared to full irrigation with 100% ETc. Crosby and Wang [50] also concluded that 25% deficit irrigation during late bulking and maturation stage could save significant irrigation water maintaining optimum tuber yield and quality, while over-irrigation with 125% ETc not being profitable compared to full irrigation in chipping potatoes. The varietal and seasonal differences in crop performance and tuber yield were also reported by Crosby and Wang [50].…”

Irrigation and nitrogen management are crucial for sustainable potato (Solanum tuberosum L.) production. A field experiment was conducted during the 2022 and 2023 growing seasons at Farmington, New Mexico, to evaluate the performance of two chip potato varieties (Lamoka and Waneta) under three irrigation regimes (full irrigation (FI), 20% deficit irrigation (DI) and 40% DI) and seven nitrogen fertilizer rates (0, 60, 115, 170, 220, 280, and 340 kg N/ha). The treatment combinations of irrigation regimes, nitrogen rates, and varieties were arranged in a split–split plot design with three replications as main plot, sub-plot, and sub-sub plot, respectively. The two-year results showed that irrigation regimes had the most significant effect on plant growth, physiology, and tuber yield of the potato varieties. For both Lamoka and Waneta, the plant height and canopy cover were lower under 40% DI than under 20% DI and FI treatments. The SPAD meter values were higher under 40% DI, followed by 20% DI and FI treatments, whereas the stomatal conductance was higher under FI, followed by 20% DI and 40% DI during both growing seasons. Regardless of nitrogen rates and variety, a 20% water-saving irrigation strategy reduced the total tuber yield by 4.5% and 22.1% in the 2022 and 2023 growing seasons, respectively, while the 40% water-saving irrigation strategy reduced total tuber yield by 36.8% and 58.2% in the 2022 and 2023 growing seasons, respectively, as compared to full irrigation. Shifting from full irrigation to 20% DI could save 711.2 to 1036.3 m3/ha of irrigation water. For Lamoka, the highest total tuber yield was obtained with 60 kg N/ha under 20% DI and 220 kg N/ha under FI in 2022 and 2023, respectively. For Waneta, the highest total tuber yield was obtained with 115 kg N/ha under 20% DI and 170 kg N/ha under FI in 2022 and 2023, respectively. Maximum water use efficiency (WUE) was obtained at 60 kg N/ha with 20% DI for both Lamoka and Waneta in 2022, while maximum WUE was obtained at 220 kg N/ha under FI for Lamoka and at 170 kg N/ha for Waneta in the 2023 season. The maximum nitrogen use efficiency (NUE) was achieved with 60 kg N/ha under 20% DI for both varieties during both growing seasons. Thus, for sustainable irrigation and nitrogen management, the application of a 20% deficit irrigation strategy with a lower nitrogen rate (60 to 170 kg N/ha) could be the best option to improve WUE and NUE with minimal tuber yield reduction. Our study suggested that 40% deficit irrigation would not be beneficial as compared to both full irrigation and 20% water-saving irrigation.

With a rising global population and looming water shortages in the U.S., there is a pressing need for water-efficient farming methods. The water needs of potato plants decrease in the late season due to foliage aging and tuber maturation. Therefore, proper late-season irrigation is vital in preventing water waste and maximizing potato profits. This study assessed the feasibility of reducing late-season irrigation to improve crop water productivity (WPc), tuber quality, and economic return. Field trials were planted near Othello, WA, across three years (2018–20). Treatments included five irrigation levels (ILs), 40%, 60%, 80%, 100%, and 120% of modeled evapotranspiration (ET), and five potato cultivars: Alturas, Clearwater Russet, Ranger Russet, Russet Burbank, and Umatilla Russet. Treatments started 100 to 105 days after planting (DAP), approximately 1500 day degrees (at or near peak canopy growth), and ended at vine kill, 150 to 155 DAP. Water from reduced ILs of 40% to 80% ET was more efficiently converted into yield (WPc) for Alturas than higher ILs; however, economic return for all cultivars typically peaked when irrigation was supplied at or above 80% ET. Tuber quality generally improved with a reduction in irrigation level, occasionally at the expense of yield and economic value.
