In the agroclimatic conditions of the Vojvodina Province, the application of an economic water regime and modern technology is necessary for stable and intensive potato production. A two-year experiment on calcareous chernozem was carried out to determine how irrigation and different pre-irrigation soil moisture affect potato yield and distribution of tuber fraction in the potato yield. The block-design trial had four replicates and was adapted for sprinkler irrigation conditions. It included four treatments: irrigation with pre-irrigation moisture levels of 60% of field water capacity (FC), irrigation with pre-irrigation moisture levels of 70% (FC), irrigation with pre-irrigation moisture levels of 80% (FC), and a non-irrigated control treatment. Irrigation significantly increased the yield of potato, which increased from 37.27% to 75.86%. Under irrigation, the percentage of small fractions decreased in favour of the 55 mm one, or fractions above the 45-55 mm range. On average, irrigated treatments produced significantly more tubers than the conditions of natural water supply.
