The experiment was conducted to study the effect of sowing the carrot (Daucus carota. Var. Nantes) on three dates (24/9, 8/10 and 23/10) and two densities: high (80) plants/m2 and low (40) plants/m2 under the conditions of Hama governorate, according to the split design. The early sowing showed a significant superiority over the other dates in all the studied traits (germination; maturity; length of leaves; length, diameter and weight of root; number of leaves per plant; fresh plant weight, and marketable productivity). The low density was significantly higher in the number of leaves per plant; length, diameter and weight of root, and fresh plant weight, while the opposite was noticed in terms of the length of the leaves and the marketable productivity. While the speed of germination and maturity were not affected with the plant density. In terms of the interaction between the date and the density, the plants that were sown on the first date at low density achieved the highest germination velocity; maturity; length, diameter and weight of root; number of leaves per plant and fresh plant weight (10 days, 118 days, 23.1 cm, 31.33 mm, 136 g, 15 leaves/plant, 158 g/plant, respectively), while the highest leaf length and marketable productivity (28 cm, 5.71 kg/m2 respectively) were achieved at the first date and high density.
