Economic Return for Maize Crop under Surface Irrigation System

The field experiment was conducted at Sidi Salem city, KafrElshekh governorate, Egypt. Located at latitude 310 27'N, longitude 300 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 (m3/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.
