Abstract
AbstractThe use of automation controllers for irrigation systems using saline water in irrigated agriculture, as a means of its disposal, was evaluated in a field experiment that was conducted in three successful seasons (2012, 2013, and 2014) at sites at the National Research Center (NRC) farm, Egypt. The purpose of the research was to study the effect of injected saline water (0, 15, and 30%), using three automation controller drip irrigation systems [surface drip (SD) and subsurface drip at both 10-cm (SSD10) and 20-cm (SSD20) soil depths] on the vegetative growth and water productivity (WP) of a wheat variety (Triticum aestivum L. CV. Gemmaiza 9). The results showed that subsurface drip irrigation (SSD20) has a preemptive effect on both wheat grain and straw yield, and the percentage of the increase was 7.11 and 6.12%, respectively, as compared with an automation controller (SD) irrigation system. Additionally, the percentage of the increase was 1.68 and 1.83% compared between automation controller (S...
