Abstract The response to potassium by a vegetable crop,Brassica chinensis Baily (Choy-sam) was studied in field experiments. The results indicated that the petiole and stem contained higher concentrations of potassium than other tissues while the leaf blades and flower contained highest concentrations of nitrogen and phosphorus. Application of potash significantly increased the yield of Choy-sam and the potassium concentration in the plant. There was no response to potash fertilizer when the ammonium acetate soluble K content of the soil was greater than 71 ± 12µg g−1.
