This study was conducted to study the performance of lucerne under water stress conditions and determine water use efficiency (WUE) for optimal forage production under the arid climatic conditions of Al-Ahsa, Saudi Arabia, having limited irrigation water supplies. Plant growth parameters of lucerne were significantly affected by different irrigation treatments. Mean lucerne dry forage (hay) yield ranged between 2.21-5.33 tonnes ha-1 in different irrigation treatments. The WUE was higher in T1 (irrigation at field capacity soil moisture level) than other water stress treatments. It was noticed that lucerne dry forage yield was severely affected by irrigation stress. In conclusion, the WUE of lucerne crop was highest in T1 (irrigation at field capacity level of soil moisture) than other irrigation treatments. The study provided an excellent opportunity for scheduling irrigation of lucerne crop for optimal dry-forage production under arid climatic conditions of Al-Ahsa.
