“…SPAD generally tends to increase with increasing nitrogen level. Lombardo et al, (2020) reported that SPAD readings were higher in N fertilizing plots than in non-fertilized plots and same result was found by Anning et al, (2022). The results showed that SPAD values increased with decreasing irrigation amount (Fig.…”

“…Fertiliser N rates may increase tuber speci c gravity and reduce sugar concentration in tubers. The excessive use of N fertilizer resulted in eutrophication of water resources, acidi cation, leaching, air pollution and yield loss, and has adversely affected sustainable energy production from agricultural soil (Anning et al, 2022). Insu cient nitrogen suppresses leaf elongation, slows growth and inhibits photosynthesis (Gregoriou et al, 2007).…”

Water and nitrogen are agricultural inputs that are widely used in potato production areas. Excessive and inappropriate use of these two important inputs causes rapid consumption of water resources and results in inappropriate nitrogen leakage. In potato production, understanding the effects of water and nitrogen on the physiological properties will help to overcome these di culties. This study was therefore conducted to determine the effects of different nitrogen and irrigation levels on the physiological (photosynthesis rate, leaf area index, leaf chlorophyll content, leaf temperature) characteristic of potato.Field experiments were conducted during the 2021 and 2022 main potato cropping seasons to select the suitable combination of irrigation and fertilization levels for potato production in the Nigde Province of the Central Anatolia Region of Turkey. The study conducted in a factorial design with six nitrogen fertilization rates and three irrigation levels. The experiment included no nitrogen (control, N0), 100 kg N ha − 1 (N1), 200 kg N ha − 1 (N2), 300 kg N ha − 1 (N3), 400 kg N ha − 1 (N4) and 500 kg N ha − 1 (N5) and I1 = 100%, I2 = 66%, I3 = 33% of Field Capacity (FC). All the measurements were taken at ve different times (40, 50, 60, 70, 80 days) after emergence. The results revealed that nitrogen treatments improve the crop physiology traits by increasing the photosynthetic rate, chlorophyll content and leaf area index, except the leaf temperature, compared with the control (no-nitrogen treatments) while the full irrigation (I1) treatment recorded the highest photosynthesis and leaf area index values. I1N3 was the most e cient treatment for both photosynthesis and leaf area index. The increase in irrigation treatments resulted in a decrease in leaf chlorophyll and leaf temperature (Pt). Leaf chlorophyll content tended to increase with increasing nitrogen, but leaf temperature did not show a regular increase or decrease. The highest N and I interaction for leaf chlorophyll content and leaf temperature were obtained from I3N0 treatment. This study identi es the most appropriate nitrogen and irrigation application for optimum physiological yield of the potato for crop producers. The study used only one commercial potato cultivar (agria), so more research should be carried out on several cultivars in order to arrive at a more conclusive conclusion, since it may be that this result is unique to agria potato cultivars only. In addition, both biochemical and physiological assessments in comparison with tuber yield should be conducted using different nitrogen and irrigation levels to assess their correlations.

The use of sulfur is an important factor in potato production. At the beginning of this study, a hypothesis was put forward according to which sulfur carrier affects yield (TY) and nitrogen efficiency (EN). The three-year study was conducted in a two-factor system: (1) sulfur fertilization, SF (control—without S, elemental sulfur—S0, calcium sulfate—CS), and (2) nitrogen fertilization level, NF (0, 30, 60, 90, 120, and 150 kg N·ha−1). In addition to TY, the following EN indicators were analyzed: agronomical efficiency (EA), physiological efficiency (EPh), partial factor productivity (PFP), and recovery (R). For both sources of sulfur, an increase in TY was confirmed. After applying CS, the optimum for the maximum yield was 106 kg N·ha−1, while the application of S0 resulted in 134 kg N·ha−1. The impact of SF on the nitrogen economy decreased in the direction of EA = PFP > EF > R and depended on the sulfur carrier. A positive trend was found, associated with the increase in R under the influence of S0 and the clearly higher EPh after the application of CS. A particularly strong effect of CS on EA was evident in the range of lower nitrogen doses. The EN values depended on the meteorological conditions during the research years. The strongest variability was subject to EPh, which, as a result of SF, was significantly higher in relation to the control (without S) during the growing season, with an unfavorable distribution of precipitation. The application of CS reduced the unit nitrogen uptake (UU-N). Using path analysis, a direct relationship of Ca accumulation (controlled by N and S) with TY was demonstrated. The conducted research indicates a significant impact of sulfur fertilizers, related to TY and EN, especially visible under conditions of limited nitrogen supply.
