Quality constituents of carrots Daucus carota L. as influenced by nitrogen and potassium fertilization

, : Quality constituents of carrots Daucus carota L. as influenced by nitrogen and potassium fertilization. Acta Horticulturae (29): 295-305

In trials with pot-grown carrots rising N levels increased the root carotene content, but no such effect from K was noted. Generally, the carotene content was more affected by the stage of plant maturity than by fertilization. The percentage of reducing sugars decreased with the addition of K and that of non-reducing sugars increased; total sugars decreased slightly. N had little effect on total sugars but increased reducing sugars and decreased non-reducing ones.
