  Rezumat:  The results of our research were obtained in Oradea, Western Romania, during 2001-2005. Maize water consumption was determined by using the water balance method on 0-150 cm profile of the soil, in both nonirrigated and irrigated conditions. Determinations made every ten days in the irrigated variant, maintained the soil moisture between easily available water content and field capacity on 0-75 cm profile of the soil. Water use efficiency was calculated by reporting the yield to water consumption. All the components of the technology applied, such as crop rotation (melioration, crop rotation of 3 and 2 years, monocrop), hybrid use, plant density (25, 40, 55, 70 and 85 thousand plants/hectare), soil tillage (plow at 25 cm and 12 cm depth, ciesel, disk), fertilization (manure, manure + N90P45), irrigation and weed control, significantly influenced the values of the maize water consumption and of the water use efficiency. These findings underline the importance of optimizing every technological component of the maize crop.
