Abstract: A field experiment was conducted with potatoes to examine the effects of hydrogel application and weather conditions on total tuber yield and the content of potentially harmful compounds - glycoalkaloids and nitrates. The first experimental factor comprised three table cultivars: Lawenda, Rima and Provita. The second factor consisted of three treatments: the application of the hydrogel AgroNanoGel Basic at 60 and 90 kg/ha, and a control treatment without hydrogel. Statistical analysis demonstrated significant effects of cultivar, hydrogel application rates, and hydrothermal conditions in the study years on potato tuber yield. The highest yields were produced by cv. Lawenda, and the most favourable yield-forming effects were observed when the hydrogel had been applied at 90 kg/ha. The levels of antinutritional compounds were significantly affected by the experimental factors and weather conditions during the study years. Cv. Rima accumulated the lowest levels of glycoalkaloids, whereas cv. Lawenda contained the least nitrates (V). The hydrogel increased the content of both glycoalkaloids and nitrates relative to the control treatment, although their levels posed no risk to human health. Higher concentrations of antinutritional compounds were recorded in the dry and warm 2024 season than in the cooler and more humid 2025 season.
