ABSTRACT

Micro irrigation system is a solid set system for supplying filtered water and fertilizers in a small quantity and under low pressure, directly near the root zone. Water through a trickle network flows in predetermined direction, starts from the water source, passing through control unit/conveying lines (main and submain), distribution pipes (manifolds and laterals) and finally to “emitters.” Micro irrigation system design is a decision-making process to match the operational, physical and economic settings. The design is based on crop water requirements, hydraulic principles, emitter characteristics; field properties, economics of the system, and criteria of water application uniformity [5].
