The experiment included two CI sources (KCI and CaCl2) and five NO3/CI percentages at 100/0, 90/10, 80/20, 70/30, and 60/40 with total-N concentration of 400 mg NO3/kg soil in 100/0 treatment. The fresh and dry weights of shoots and storage roots, and the length and diameter of storage roots increased significantly more with mixed NO3 /CI treatments and CI sources than with single NO3 (100/0) treatment. Growth was enhanced up to the 80/20 NO3/CI treatments. With CI present in the treatments, the concentration of total-N unchanged and NO3 decreased, and CI and K increased both of the CI sources. In KCI treatments, Na absorption decreased Calcium content significantly differed among the treatments. It was concluded that nitrogen fertilization provided with combined CI forms and NO3/CI percentages can enhance the quality of carrots and at the same time derease the N fertilizer input rate.
