Abstract: A study was conducted to evaluate the performance of drip irrigation system for vegetable crop sequence. Three level of drip irrigation viz IW/CPE ratio 0.5, 0.75 and 1.0 (low, medium and high) were selected to irrigate the paired row planted crop. Similar planting technique was used for furrow irrigation method. Two years study shows that yield of green chilly (variety Sanour Anal) and cauliflower (variety Pusa Snowball) was significantly higher at low level of drip irrigation as compared to medium, high level of drip irrigation and furrow irrigation method. Low level of drip irrigation resulted in 30 and 38 percent higher yield as compared to furrow irrigation for green chilly and cauliflower, respectively. At the low level of drip irrigation, drip saves 63.3 and 38.5 percent of water for chilly and cauliflower crop, respectively as compared to furrow irrigation. Irrigation Water Use Efficiency was maximum (1021.6 kg/ha-cm) at low level of drip irrigation and minimum (316.56 kg/ha-cm) with furrow irrigation for the whole crop sequence. If one considers the full crop sequence, low level of drip gave 222.7 percent increase in the irrigation water use efficiency, 58.6 percent saving of irrigation water and 33.6 percent increase in crop yield as compared to furrow irrigation.
