This work was carried out to evaluate the effect of garlic (Allium sativum) and carrot (Daucus carota) intercropping at four carrot sowing times under three weed control systems on weed control, yield, profitability and commercial quality, in Caçador-SC - Brazil. Four carrot seeding times (0, 15, 30 and 45 days after planting garlic) and three weed management systems (with herbicide, frequent manual weeding and no weed control) were tested. The experimental design was a randomized block with split-plots and four replications, with carrot seeding times being the plots and the weed management systems, the sub-plots. The herbicide oxadiazon at 750 g ha-1 did not cause toxicity in the garlic, nor in the carrot plants. Garlic-carrot intercropping profitability was greater than that of garlic monoculture, mainly under frequent manual weeding.
