Daily last time of irrigation in perlite bag culture was investigated to get high water use efficiency (WUE) and fertilizer use efficiency (FUE) and also sustain high productivity for tomato. The water content in the substrate was higher as the last time of irrigation was later from 4 to 1hour before sunset. The growth were not significantly different in all treatments. The marketable yield was the highest in treatments of 1 or 2hours before sunset and the lowest in treatment of 4hours. In the result to investigate for 128days WUE and FUE were the lowest in treatment of 1hour before sunset but the highest in treatment of 3hours before sunset. In the conclusion, it looks best to end irrigation 2~3hours before sunset in the aspects of plant growth, yield, WUE, and FUE.
