A field study on replacing traditional flood irrigation of sugarcane crop in upper Egypt with drip irrigation technique

Abstract

This study assesses the agronomic and economic advantages of replacing traditional flood irrigation with drip irrigation for sugarcane cultivation in water-scarce Upper Egypt. Confronting severe water shortages and inefficient conventional practices, we conducted a three-year comparative field study assessing crop yields and water use efficiency. The results reveal that drip irrigation improves water-use efficiency by 44% and increases sugarcane yields by 22% relative to flood irrigation, while also elevating net profits by 50%. Drip irrigation demonstrated an average efficiency of 85–90%, compared to 50–60% for flood irrigation. These findings underscore the dual benefits of drip irrigation in addressing water scarcity and enhancing agricultural productivity. The study provides compelling empirical evidence supporting drip irrigation as a sustainable solution for arid regions. To ensure long-term water resource sustainability and food security, we urge policymakers and agricultural stakeholders to prioritize large-scale adoption of drip irrigation systems through targeted investments and policy interventions.
