The research was carried out at ARDS Marculesti, Calarasi County, Romania, in 2017, 2018 and 2019 years. The experiment had two factors, namely: the maize hybrid and the irrigation regime. The investigated maize hybrids were: P9175 (FAO 330), KWS BELLAVISTA (FAO 330), KWS SMARAGD (FAO 350), KWS KASHMIR (370 FAO) and KWS DURANGO (FAO 480). Four irrigation regimes were researched: rainfed, stressed at and after flowering, stressed before flowering and full irrigated throughout the vegetation period. The yield results obtained in the three years of experimentation showed that the lowest yield was obtained for the hybrid P9175, of 10,920 kg/ha. The hybrids Durango, Kashmir and Smaragd gave very significant positive differences compared to the hybrid P9175 taken as a control; these production differences were between 890 and 1760 kg/ha. The Bellavista hybrid gave yields close to those of the P9175 hybrid. Regarding the moisture content of grains at harvest, the lowest values were obtained by the hybrid P9175.
