Deficit irrigation is a water management strategy used in agriculture to intentionally apply less water than the full water requirements of the crop. This approach aims to optimize water use efficiency and increase water productivity in irrigation systems. By strategically limiting water application, farmers can induce controlled stress on the crops, which can lead to better resource allocation, improved crop quality, and potentially higher yields. Deficit irrigation is often used in regions with limited water availability or where water resources are scarce. It requires careful monitoring and management to ensure that water stress does not negatively impact crop growth and yield.
