An experiment was carried out at Caatinga Experimental Field of Embrapa Tropical Semi-Arid, Petrolina-PE, Brazil, in the first semester of 1998, with the objective of evaluating the effect of different levels of salinity of irrigation water with and without the soil conditioner on the yield of carrot, cv. Brasília. The experiment was set up in a randomized complete block design with six treatments and four replications. The treatments consisted of water with electrical conductivity of 0.1 dS/m (control - from the São Francisco river), 4.0 and 8.0 dS/ m, and the same levels of electrical conductivity plus soil conditioner. The carrot yields varied from 33.1 to 82.3 t/ ha, for the treatments irrigated with saline water plus soil conditioner and for the control, respectively. Also, there was no significant difference between the yield obtained using water from the São Francisco river (0.1 dS/m) and that obtained using water with 4.0 dS/m electrical conductivity and that obtained with the application of soil conditioner.
