Abstract
The effect of nitrogen availability on dry matter production, nitrogen uptake and marketable yield of Brussels sprouts (high crop residue) and leek (low fertilizer recovery) was analysed in a field experiment. All available soil mineral nitrogen (from fertilizer and mineralisation) was taken up by Brussels sprouts up to 430 kg ha-1 and by leek up to 250 kg ha-1, when 300 and 125 kg ha-1 nitrogen fertilizer was applied respectively. Maximum dry matter production was almost reached when those amounts of nitrogen were taken up. Optimum marketable yield was achieved at still higher nitrogen rates; with leek the optimum application rate was associated with nitrogen losses, and with Brussels sprouts it led to high amounts of nitrogen in the crop residue.
