Different irrigation methods and water stress effects on potato yield and yield components

Water use efficiency (WUE) of SD irrigation methods had generally higher values than SSD irrigation methods. Treatment I33 gave maximum irrigation water use efficiency (IWUE) for both years. SSD irrigation method did not provide significant advantage on yield and WUE, compared to SD irrigation in early potato production under experimental conditions. Therefore, the SD irrigation method would be recommended in early potato production under Mediterranean conditions.
