Assessment of Brackish Water Usability for Irrigating the Coastal Sugarcane Fields under the Background of Saline Intrusion

Background: Globally, irrigation water deficit (IWD) due to saline intrusion and decreased rainfed continues affect coastal cultivation regions (CCRs). Coastal lowland have increasingly frequent intrusion, resulting in the IWD as a part of climate variability. Cu Lao Dung Isle, terrain-low plain Vietanm is facing revenue loss adverse conditions recent years. Methods: The objective this study was, therefore, assess effectiveness mixture brackish freshwater (MBF) for irrigating spring crop sugarcane 2019/20 season grown household farming Isle. An experiment was exploded with MBF varying from 1.5 5.0 dS m-1 corresponding 100 120% evapotranspiration (ETc). Determination daily ETc conducted simulating FAO-Penman Monteith model based on weather data obtained using an automatic station, locating area. Result: Based findings, at 3.0 levels stated be suitable normal growth Khonkaen III variety. results showed that increasing 3.5 significant influenced process yield sugarcane. In general, utilization CCRs solution economic efficiency.
