Abstract
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 1st and 2nd 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.
