This study assed the common chicory (Cichorium intybus), performance in soil fertilized with aquaponics sludge. The experimental design consisted of three treatments with three repetitions: (1) fertilization with aquaponic sludge; (2) chemical fertilization (NPK); and (3) control (without fertilization). The sludge (80 L) was collected twice a week from the bottom of two clarifiers, homogenized, and later applied to the soil. The results of culture performance and the composition of the plant tissue were evaluated, comparing the phytotechnical parameters of each vegetable between treatments in the soil and a comparison between cycles for each treatment. The production of common chicory in the 1st cycle showed no differences between the Sludge and NPK treatments, and both were superior to the Control in all phytotechnical parameters. In the 2nd cycle, there were differences in the parameters of the length of the largest leaf, fresh mass and dry mass, with higher values registered in plants fertilized with sludge than in those treated with NPK or Control. This results suggests a cumulative effect of nutrients in the soil after successive sludge applications combined with the mineralization of nutrients, making them available in soil. Higher concentrations of P in the leaf tissue of the common chicory in the Sludge treatment suggests higher rates of absorption of this element. The aquaponic sludge can be used to fertilize vegetables in the soil and obtain yields equivalent to or even higher than those of mineral fertilization.
