Leaf blades and petioles of six horseradish cultivars were sampled at two stages of growth and analyzed for N, P, K, Ca, Mg, S. Mn, Fe, Zn, B, Cu, and Na composition. Based on these data, sampling of leaf blades at the fern-leaf stage are recommended for the purpose of using plant analysis to monitor a soil fertility program for production of horseradish. Nutrient concentrations of this plant part at this growth stage showed the cultivars ranged from 2.01 to 2.98% N, 0.20 to 0.32% P, 2.40 to 3.78% K, 2.41 to 2.94% Ca, 0.26 to 0.31% Mg, 0.62 to 1.16% S, 127 to 230 ppm Mn, 56 to 145 ppm Fe, 44 to 65 ppm Zn, 42 to 66 ppm B, 10 to 12 ppm Cu, 269 to 390 ppm Na, and marketable yields ranged from 3,091 to 9,520 kg/ha.
