摘要：There is a worldwide effort to produce food with less water consumption, due to scarcity trend of this resource.The study aimed to evaluate water productivity, simulated by the decision support model CSM-CERES-Maize, for irrigated maize sown at different dates.Simulations were made based on management conditions of Riacho´s Farm, located in Matozinhos, Minas Gerais State, Brazil.One observed large seasonal and interannual amplitude on crop water requirement and water productivity values.The highest water productivity values of 1.73 to 1.81 kgm-3 were observed between February 6th and 27th, a period that coincides with recommended maize crop sowing window in region.The simulation model proved to be a useful tool for planning and optimizing water resources use.
