    This research was carried out in order to determine the effects of different dripper space and water stress levels on total fruit yield, irrigation water use efficiency (IWUE) and water use efficiency (WUE). The randomized split block experimental design with three replications was applied in the study. Each row of the experimental plots was equipped with a single lateral. Dripper spacings of 25, 50 and 75 cm along the lateral were tested for main plots, while four levels of water supply (i. e. water amount applied to replenish the water deficit of 0-60 cm soil depth to field capacity (I 1) and water supply reductions of 25, 50 and 75%) were applied as sub-plots of the experiment. Results of the field experiments carried out during experimental years showed that the highest total fruit yield (73.4-74.0 t/ha) was obtained under conditions of I1 application (P<0.01). It was also determined that IWUE and WUE values varied in the ranges of 9.6-37.1 kg/m3 and 8.7-14.0 kg/m3, while seasonal values of yield response factor (ky) obtained for the first and the second experimental years were determined as 1.22 and 0.84, respectively.
