Although initially introduced to irrigate highly productive crops and orchards, where water was scarce and costly and in areas of irregular topography, pressurized irrigation systems are now used to irrigate a wide range of crops and orchards and under diverse conditions.
The optimal design of pressurized irrigation systems can be an important way of increasing agricultural profit by investing in a more efficient irrigation method. Parameters that need to be considered in pressurized irrigation design are: pipe diameter and length; number, discharge, and working pressure of the emitters; number of subunits; number of subunits operating simultaneously; and number of laterals per subunit or number of laterals that operate simultaneously for mobile systems.
The initial cost of pressurized irrigation systems is generally high and constitutes one of the principal disadvantages. Design models for drip irrigation have been developed to minimize implementation costs while satisfying maximum water requirements.
