Abstract

Sprinkler irrigation system was designed and built in response to the need, to irrigate fields and gardens using a technique that would simulate natural rainfall if it were unavailable during the dry season. Research on irrigation farm enhancement is scarce throughout the southern region, according to the data that is currently available. The purpose of this study was to build an irrigation system for carpet grass (Axonopus affinis) that uses pressurized water application efficiently to increase crop output productivity on both small and large farms. The design was predicated on irrigating a small plot using a rotating sprinkler system (a pump, plastic pipes, and fittings such as t-joint, end-plug, elbow-joint, pegs, sprinkler nozzles, measuring tape, risers, and hydrometer apparatus such as stopwatch, beakers, millimeter sieve, pestle, and volumetric flask), which offers a valid scientific foundation for appropriate water scheduling, system evaluation, and reducing water waste and runoff. The sprinkler nozzle was designed for crops and was tested on a lawn of 12 m by 8 m. The outcome demonstrated that the sprinkler's discharge rate was calculated to be 12.01 mm/h, and the sprinkler's application rate was 17.155 mm/h, its sprinkler spacing range was 10 m, and the irrigation period was assessed at 6 h. The evaluation of delivery performance ratio (DPR) and coefficient of uniformity (CU) both recorded 86% and was sufficient to suggest the system to irrigators. This system is feasible and less expensive to employ locally made materials and the effective specifications required for sprinkler irrigation.
