ABSTRACT Among the determining factors of yield, nitrogen (N) fertilization and the correct supply of water play an important role in the quality and yield aspects of coriander. Therefore, the aim of this study was to evaluate the yield components and the water use efficiency (WUE) in coriander subjected to different depths and N doses. A completely randomized design in split plot was used. Water depths were applied in the plots at the rates of 25, 50, 75, 100 and 125% of the Required Real Irrigation (RRI). N doses were distributed within the subplots at the following proportions: 50, 100 and 150% of the recommendation for the crop (70 kg ha-1). The N dose of 94 kg ha-1 and irrigation depth of 115% of RRI promoted the greatest yield (29.0 t ha-1) and number of bunches (29 bunches m-2). The highest number of leaves per plant was obtained with the N dose of 103.2 kg ha-1 and irrigation depth of 68% of the RRI. The maximum plant height (43 cm) was obtained with N dose of 105 kg ha-1 and irrigation depth of 121% of RRI. The highest WUE in coriander (71 kg m-3) occurred at the irrigation depth of 26% of RRI and N dose of 105 kg ha-1.
