Most scenarios of climate change in Poland predict an increase in air temperature in the coming years. However, no significant increase in precipitation is forecast. Therefore, an increase in the water needs of plants should be expected, which requires the development of irrigation systems. To precisely determine the schedule of crop irrigation, it is necessary to investigate the water needs of plants and to estimate the prospects of changes in the future. This research aimed to estimate the water needs of Jerusalem artichoke in the period 2021–2050 in the Kuyavia region located in central Poland, where the need for supplementary irrigation is the highest. Based on the calculations, it was found that, in the growing season (21 May–30 September), an increase in the water needs of Jerusalem artichoke, of 26 mm, i.e., 9%, should be expected. The highest increase of 10 mm (i.e., by 16%) is expected in August. The results of our studies are utilitarian in character and can be used for the preparation of a strategy for the development of irrigation systems for Jerusalem artichoke cultivation in central Poland.
