The present study aims to assess current irrigation management practices in two totally different soil types and climatic conditions case studies at Tina Plain (AER1) and East South El-Kantara (AER2), Egypt. Net irrigation water requirements (NIWR) for eight crops were computed using the FAO-CROPWAT8 model. The results showed increasing in NIWR of about 25% for cultivating crops in AER2 compared to AER1. The current free crop pattern indicated 22.5% potential water savings compared to available water resources under surface irrigation efficiency of 40% in AER1 (clay soil) and 60% for surface, drip, and sprinkler irrigation in AER2 (sandy soil). Different crop pattern scenarios were tested and their income optimization was computed. Suggested scenarios showed Greenbeans and Sugarbeet crops had the maximum income (44% water saving). Whereas, Berseem clover and Cotton had minimum income and can cause 24% water shortage. Improving irrigation efficiency and cultivating Greenbeans and Sugarbeet are recommended.

本研究旨在评估埃及蒂娜平原 (AER1) 和东南埃尔坎塔拉 (AER2) 两种完全不同的土壤类型和气候条件案例研究中当前的灌溉管理实践。八种作物的净灌溉用水量 (NIWR) 使用 FAO-CROPWAT8 模型计算。结果表明，与 AER1 相比，在 AER2 中种植作物的 NIWR 增加了约 25%。当前的自由作物模式表明，与可用水资源相比，在 AER1（粘土）的地表灌溉效率为 40% 和 AER2（沙土）的地表、滴灌和喷灌效率为 60% 的情况下，潜在节水率为 22.5%。测试了不同的作物模式场景并计算了它们的收入优化。建议的情景显示绿豆和甜菜作物的收入最高（节水 44%）。然而，Berseem 三叶草和 Cotton 的收入最低，可导致 24% 的水资源短缺。建议提高灌溉效率并种植绿豆和甜菜。
