Comparative research on water and energy-saving irrigation systems in the GAP and Aegean regions of Turkey
This research was carried out to determine the effects of furrow, sprinkler, drip, mobile nozzle, mobile drip and LEPA (Low Energy Precision Application) irrigation methods on the yields and Water Use Efficiency of cotton in the South Eastern Anatolian Project (GAP) Area and in the Aegean Region. According to the results obtained, the highest yield was produced from the drip irrigation method. The drip, sprinkler and mobile nozzle forms of irrigation require 31, 28 and 26% less irrigation water respectively than furrow irrigation when related to the optimum yields and the feasible irrigation water quantities in the GAP Area. The drip irrigation method has utilised the irrigation water more efficiently than the other methods. LEPA and mobile drip did not show any significant difference in the effective use of irrigation water compared to furrow irrigation. Similar results were obtained in the Aegean Region of Turkey.
