Twelve irrigation trials with autumn sown sugarbeet [Beta vulgaris var. saccharifera] were conducted during 2003-2005 at six sites in Andalucia (Spain) on mainly clayey soils. Moderate deficit irrigation (10% less than the crop evapotranspiration, ETc, in May and 15% less in June and July) and severe deficit irrigation (10% less than the ETc in April and 20% less in May, June and July) were compared with unstressed control. Ten trials were valid. The control received 365 mm of irrigation water, the moderate and severe treatments received 10% and 15% less water than the control, respectively. The results show that the application of less water at the end of the crop cycle did not result in the loss of sugar yield, farming gross revenues or quality, despite a decrease in beet yield (by 5 tonnes/ha), as water stress significantly increased sugar content, as well as water use efficiency (WUE) by 7 and 14% in the moderate and severely stressed treatments, respectively.
