Maize is a drought-resistant plant, a feature ensured by low water consumption, the highly developed and deep root system, and has the ability of the plant to adapt to drought conditions by reducing the perspiration surface. In this paper, the water productivity model simulation Aquacrop was used for maize crop. AquaCrop is a crop water productivity model developed by the Land and Water Division of FAO to address food security and to assess the effect of environment and management on crop production. AquaCrop simulates yield response to water of herbaceous crops, and is particularly suited to address conditions where water is a key limiting factor in crop production. There were analyzed climatic, water, soil and crop parameters from April 1st to August 31 for the years 2014-2017 for maize crop. In the Aquacrop model we used two different methods for evaluate the evapotranspiration: simulated Evapotranspiration with ETo Calculator module and calculated Evapotranspiration using Penman-Monteith. Constantly monitoring and observation the risk/stress phenomena, lead to the most effective measures to prevent and mitigate the effects on the obtained agricultural productions.
