Abstract

The field experiment was conducted at Sidi Salem city, KafrElshekh governorate, Egypt. Located at latitude 31 0 27' N, longitude 30 0 78' E and 6,1m Altitude during season 2023 to determine the performance of alternate furrow irrigation and effect of water deficit by reducing the water applied. The treatments were two alternative irrigations first, irrigated one furrow and non-irrigated one furrow second, irrigated two furrows and non-irrigated one furrow. Two Surface irrigation systems, developed irrigation and traditional irrigation. Three levels of irrigation water applied (100% ETc, 85% ETc and 70% ETc). The results showed that the yield and water use efficiency increased by 15.40% and 32.43% respectively, as the application of water (m 3 /fed.) decreased by 19.49% compared with those in the plot that irrigated with traditional irrigation. The cost of irrigation (LE/fed.) in the developing plot was decreased by 82.11 % compared with traditional irrigation. The net return (LE/fed.) increased by 18.17% compared with traditional irrigation. The yield of the developed surface irrigation for two furrows irrigated and one furrow non-irrigated increased by 9.09, 1.30 and 9.47 % compared with developed surface irrigation using one furrow irrigated and one furrow non-irrigated, developed surface irrigation using two furrows irrigated and one furrow non-irrigated and traditional irrigation surface irrigation using one furrow irrigated and one furrow non-irrigated respectively. Application efficiency (Ea) decreased by 5.95 and 16.09 % when the ETc decreased from 100 % to 85% and from 100% to 70%, respectively.
地表灌溉系统下玉米作物的经济收益
田间试验在埃及 KafrElshekh 省 Sidi Salem 市进行。实验地点位于北纬 31 0 27',东经 30 0 78',海拔 6.1 米,时间为 2023 年,目的是测定交替沟灌的效果以及减少施水量对缺水的影响。处理为两种交替灌溉,第一种是灌溉一沟和不灌溉一沟,第二种是灌溉两沟和不灌溉一沟。两种地表灌溉系统:发达灌溉系统和传统灌溉系统。三种灌溉水量(100% ETc、85% ETc 和 70% ETc)。结果表明,与采用传统灌溉方式的地块相比,产量和用水效率分别提高了 15.40%和 32.43%,而用水量(m 3/fed.)减少了 19.49%。与传统灌溉相比,发展中地块的灌溉成本(LE/fed.)净收益(LE/fed.)比传统灌溉增加了 18.17%。开发式地表灌溉的两沟灌溉和一沟不灌溉产量分别比开发式地表灌溉的一沟灌溉和一沟不灌溉、开发式地表灌溉的两沟灌溉和一沟不灌溉以及传统灌溉的一沟灌溉和一沟不灌溉增加了 9.09%、1.30% 和 9.47%。当 ETc 从 100% 降到 85% 和从 100% 降到 70% 时,施肥效率(Ea)分别降低了 5.95% 和 16.09%。
