<Para ID="Par1">MATLAB<Superscript>™</Superscript> software named PRESUD (Pressurized Subunit Design) was developed to identify the optimum solid set sprinkler irrigation subunit design with a criterion of minimizing the annual water application cost (C<Subscript>T</Subscript>).

The PRESUD tool was developed using MATLAB™ to identify the optimum microirrigation system design. The lowest cost was determined by calculating the annual water application cost per unit of irrigated area (CT). This is defined as the cost of one cubic meter of water applied to crops, and is...
