This work aimed to evaluate weed interference in yield and quality of carrots (Daucus carota). An experiment was carried out in a randomized block design, with four replications. The treatments were composed of six periods of weed control (0-12, 0-24, 0-36, 0-48, 0-60 and 0-72 days after emergence (DAE)). The characteristics evaluated were: yield of commercial roots, total soluble solids (TSS), total titratable acidity (TTA), vitamin C, TSS/TTA ratio and pH of roots. The commercial root yields decreased with weed interference, with weed control being required until 36 DAE. Root TSS rates and vitamin C did not vary with weed interference. The presence of weeds for a longer period increased pH and TSS and decreased TSS/TTA ratios.
