Abstract: Yield and quality responses of `Market Prize' cabbage to five nitrogen sources and five rates of each source were measured in a replicated test at Clemson and Florence, SC in 1987 and 88. Soil nitrate solution, analyzed by the ion-electrode method, was monitored bi-weekly with maintenance levels kept throughout the growing season at or above threshold levels of 5, 10, 15, 20, and 30 ppm. The 15-0-14 (nitrate of soda/potash) gave higher total and early yields; higher levels of soluble solids and dry weights when compared to other N-sources of sodium-, ammonium-, potassium-, and calcium nitrate. Uptake, as measured by leaf tissue nitrate ion concentration, increased across soil solution levels up to 20 ppm.
