Abstract : ABSTRACT. This study was conducted at Hada Al-Sham Agricultural Research Station (King Abdulaziz University) Makkah Area to determine the effects of irrigation quantity (50%, 100% and 150% of yearly average of water requirements) and phosphorus fertilizer (0, 75, 150 and 225 kg.ha) on forage yield , water use efficiency of alfalfa plant and its phosphorus uptake. The results showed significant differences among irrigation treatments and phosphorus fertilization regarding yield (fresh and dry) and water use efficiency of alfalfa plant and its phosphorus uptake. The third irrigation treatment (150%) produced higher values of yield (fresh and dry) and phosphorus uptake compared to the other irrigation treatments. However, water use efficiency was higher for the first irrigation than the other irrigation treatments. In addition, the results showed that the interaction between irrigation treatments and phosphorus fertilization had significant effects on phosphorus uptake but not in yield (fresh and dry) and water use efficiency
