Abstract
The experiment was conducted to develop and evaluate surge flow irrigation under different slopes and discharges against continuous irrigation under traditional levelling in terms of irrigation and water use efficiencies to produce wheat crop in clayey soil. It was carried out at the experimental farm, Faculty of Agriculture, Kafrelsheikh University, during the winter season 2013/2014. The treatments for surge flow irrigation consisted of three slopes (0.0, 0.1 and 0.2%), three discharges (0.4, 0.55 and 0.75 l/s), and two cycle ratios (1/2 and 2/3) in addition to, treatments of continuous flow for the same discharges under traditional levelling. The discharge was measured using control valve and flowmeter which manufactured to measure and control the applied irrigation water to each treatment.
Results indicated that surge irrigation under different slopes reduces amount of irrigation water applied, increases advance time, irrigation uniformity, water application efficiency, grain yields and water use efficiency compared with continuous flow irrigation under traditional levelling.
