Food and environmental security, water deficiency, and promoting input use efficiency are global concerns in the agricultural sector. An experiment was conducted at the Al-Ghuraira area, Esna center, Luxor Governorate, Egypt, during the 2020-21, and 2021-22 winter seasons, to evaluate the feasibility of 3 intercropping patterns (IP₁: 100% wheat cv. Shandweel-1+50% faba bean, IP₂: 100% wheat cv. Giza-171+50% faba bean, and IP₃: 100% wheat cv. Sids-12+50% faba bean) that their seeds soaked for 6 hours in certain of three Gibberellic acid (GA) concentrations (0.0, 100 and 200 ppm), under water-deficit for increasing farmer profitability in sandy soil. The results showed that irrigation treatments, soaking in GA₃, and intercropping patterns significantly affected all tested traits for wheat and faba bean crops except water use efficiency trait for faba bean in the first season. Irrigation with 100% of ETc (I₁) for wheat and faba bean as sole crops or intercropping pattern of IP₃ increased yield and its components, and decreased water use efficiency (WUE) and economic water productivity (EWP) in both seasons. Soaking seeds at GA₂₀₀ ppm induced a significantly increased in all studied traits for sole crops and intercrops than un-soaked one, in both seasons. The highest mean value of WUE (1.64 and 1.66 kg m^-3) for wheat and (0.379 and 0.387 kg m^-3) for faba bean were acquired from the IP₃, in the 1^st and 2^nd seasons, respectively. As a result, I₁×GA₂₀₀×IP₃ treatment proved to be the most effective practice on intercrop yield, the lowest competitive pressure, and the highest farmer profitability, hence could be recommended in sand soil under a drip irrigation system.
