The scientists wanted to figure out the best way to water chickpeas and coriander growing together, focusing on getting higher yields. They tested five irrigation methods: flood, furrow, sprinkler, drip, and a control with no added water. Drip irrigation gave the best yield (11.78 q/ha), followed by sprinkler irrigation (10.75 q/ha), with the control having the least yield (5.22 q/ha). Using drip and sprinkler irrigation had the highest profit compared to other methods. Drip irrigation was the most effective at using water efficiently, needing 4.71 kg of water to produce 1 kg of crop, while the control needed more water for the same result (2.08 kg of water per kg of crop).
