Abstract: In the rain-fed production system area, vegetables normally can be grown in wet season (> 200 mm/month) between December and April. During dry season (<200 mm/month) between May and October, vegetable farmers have serious problem in water availability. Periodic shortage of irrigation water during dry season leads to drought and decreased yields. Drip irrigation systems have the highest potential water application efficiency of the irrigation system used in commercial vegetables production. Drip irrigation is a tool to reduce water use, increase fertilizer efficiency, and improve profit, while simultaneously reducing the potential risk to the environment due to enrichment of surface and ground water. This research was conducted to evaluate the effect of Low Cost Drip Irrigation System on the yield of Amaranth (Amaranthus sp), Kangkong (Ipomoea reptans), Yard Long Bean (Vigna unguilata), Green Bean (Phaseolus vulgaris), and Katuk (Sauropus androgenous) growth and yield during wet season. The result showed that there no significant response of vegetable yield to the drip irrigation application during wet season. The experiment should be conducted on the dry season to evaluate the effectiveness of drip irrigation on traditional vegetable production.
