Oil palm (Elaeis guineensis Jacq.) is an oilseed crop of great economic importance. The oil palm industry has a large-scale production worldwide and uses high efficient extraction and refining processes to obtain palm oil and palm kernel oil. In Brazil, currently, there is an extensive area suitable for oil palm planting outside the Amazon rainforest; however, these areas go through long periods of water scarcity and demand artificial irrigation to be sustainable. One-quarter of the irrigated area in agriculture has a problem with salinity stress.
