The total emitter flow variation indicates the degree of uniformity of output from a trickle/drip irrigation system into the field which is a key factor to determine irrigation application efficiency and scheduling. The total emitter flow variation is mainly affected by hydraulic design, manufacturer's variation, temperature changes and plugging. Assuming the temperature variation is small and the plugging problem is under control, the total emitter flow variation will be a combination of hydraulic variation and the variation caused by the manufacturer. It is very important to know the total emitter flow variation, the hydraulics and manufacturer's, so the proper irrigation schedule can be made based on the uniformity of the drip irrigation system selected and designed.
