Maize cultivation in Portugal is closely linked to irrigation, taking advantage of the soil and climate potential offered by its geographical location, but also because this location makes irrigation an essential contribution to the crop's vegetative development (ANPROMIS, 2023). In 2023, the maize production area accounted for 91,785 ha of Portugal's agricultural area, of which 85.2 per cent is irrigated and 14.8 per cent is non-irrigated. The main maize producing region in Portugal is the Centre of the country, specifically the district of Santarém, accounting for 20.4% of the national production area (IFAP, 2023). In evolutionary terms, the wheat production area in 2023 decreased by 67.2% compared to 2013, representing a decrease of 44829 ha in the production area over ten years. In fact, national maize production has been on a downward trend in recent years, leading to a gradual increase in imports of this product. Portugal is not self-sufficient in maize production, with only 35% of the wheat consumed coming from domestic sources (IFAP, 2023; Costa ,2023).
