Pistachio trees are capable to be profitable under rain-fed conditions. They also have a good response to low amounts of irrigation water, so are a great candidate to be considered for water-scarcity scenarios. The pistachio tree has a singular way of alternate bearing, losing a percentage of its floral buds in the year preceding the harvest year. This percentage of abscission of the fruit buds increases in situations of water stress, making irrigation strategy follow as a 1-year determinant for the next season fruit yield. Despite its high resistance to severe water stress conditions, the pistachio tree has high water requirements. To overcome this issue, regulated deficit irrigation (RDI) was tested as a technique to save water without affecting yield. Coupling the use of plant biosensors to this technique is a research approach that can improve its efficiency. The recourse to these techniques created a greater preference of the resultant product by the consumer.
