Drought is the limiting factor that manifests itself on the largest agricultural area.The agricultural areas most vulnerable to soil water scarcity are those of Dobrogea, the south of the Romanian plain, the south-east and east of Moldova, as well as the west of the Tisei Plain. The purpose of the research was to calculate the moisture deficit and the need for water for irrigation based on climate scenarios made with different global climate models, as well as determining the water consumption of irrigated crops according to the expected climate change in the Romanian climate regime. In order to predict the effects of climate change, it was followed in the areas served by Constanta and Tecuci weather stations the modification of the elements of the irrigation regime in case of possible increases in average temperatures by 20C respectively 50C. The management of irrigation water in a given area was established according to the estimated moisture deficit as the difference between water consumption and useful rainfall during the growing season of crops.
