This study was carried out during the summer season of 2009 in greenhouse cucumber production at farmer condition in Izmir-Turkey. Two consecutive short cycle crop production was realized. A full irrigation (no stress) and two deficit irrigation treatments in which soil water content was allowed to be depleted to 40% (Deficit 1) and 60% (Deficit 2) of the available water content in the plant root zone, were compared with the local farmer's practice. According to the results, total yield was the highest in Full irrigation treatment followed by Farmer's treatment. Recorded total amount of irrigation water were 653 mm for Full Irrigation, 557 mm for Deficit 1, 445 mm for Deficit 2 and 699 mm for Farmer's treatments. During the automated irrigation period in whole growing season, drainage water was only received from Full irrigation (11 mm) and Farmer's treatments (89 mm). The Water Use Efficiency based on yield and irrigation water applied was the highest in Full irrigation (53.0 kg m(-3)) whereas it was the lowest in Farmer's treatment (45.0 kg m(-3)). Calculated average water-saving ratio in controlled irrigation treatments in comparison with farmer practice showed that it could be obtained 15, 14 and 6% water saving with Full irrigation, Deficit 1 and Deficit 2, respectively.
