Agriculture is known to accounts for about 70 – 80% use of available water in the world. However, dwindling water availability has made it necessary to improve on the way water is used in Agriculture. Rainfall is the single most important factor affecting crop production. The objective of this study is to develop a gravity drip irrigation system for selected vegetable crops. This study was carried out in Auchi Polytechnic, which is located between latitude 70 10’ and 70 20’ north of the equator and longitude 60 16’ and 60 36’ east of the Greenwich Meridian with an altitude of 207m. Field preparation was done by clearing, ploughing and harrowing. PVC pipes were laid, 2 mm holes was made at distance of 30 cm on the 6 m PVC pipes. Components of drip irrigation system consist essentially of main line, sub mains, laterals and emitters. The main line delivers water to the submains and the submains to the laterals. The set up was tested to determine the uniformity of water emission from the drip emitters into the field, maize, pepper, tomatos was used as the test crops and there was uniform growth observed across the entire field. The low cost drip system developed in this study showed a high level of efficiency and uniformity of water emission across the entire study area.
