• It is best to install the irrigation system 1 week after planting the cashew nuts so that the cashew nuts are strong enough, because the installation activity can damage the newly planted cashew trees.
• Each tree should have 2 water discharge heads, placed about 1 m from the base of the plant.
• Cashew nuts are long-lived crops whose growth stages are divided according to their age because they need water, which varies according to their age, from the first to the eighth year.
• Irrigation is done only once a week, applying irrigation to 1 hectare of land.
