In previous field experiments in China, there were strong relative responses of oilseed rape (Brassica napus) to zinc (Zn) at the rosette stage, and a weakening of the response with time suggesting that oilseed rape experienced a temporary Zn deficiency after transplanting. In the present study, the objective was to test the hypothesis that transplanted oilseed rape had a higher fertilizer Zn requirement for maximum growth during its recovery from transplanting than direct sown plants. Early root growth of transplanted seedlings required higher external Zn for maximum growth than that of direct sown seedlings. In conclusion, transplanted oilseed rape appears to be especially sensitive to Zn deficiency.
