In each plot 100% ETc was restored
when 40% of total available water was depleted, according to the
evapotranspiration method of Doorenbos and Pruitt (1977). In
the 2 years of experiment, a total of 370 and 440 mm of irrigation water were applied in 2010 and 2011 respectively, following
a twice-a-week irrigation schedule in both cropping systems
