In Egypt, where water is scarce, a study focused on optimizing drip irrigation for wheat on clay soil. They tested different irrigation setups and intervals to see how they affected crop yield and water use. The best result came from using two lateral lines and watering every 8 days, which gave the highest grain yield and water productivity. Watering every 12 days with a single line was less effective. The findings showed that with the right drip irrigation setup and interval, farmers can grow more wheat, use water efficiently, and save water for other purposes. This research can help farmers in areas with clay soil to improve their crop yields and make the most of limited water resources.
