- Intervention effect 150 kg N ha-1 limited yield increments above 44 000 plants per hectare.
- Intervention effect At 300 kg N ha-1, 63 000 plants per hectare yielded significantly more heads than 44 000 plants.
- Intervention effect At 300 kg N ha-1, 74 000 plants per hectare yielded significantly more heads than 44 000 plants.
- Recommendation The authors propose 45 by 40 cm spacing, giving 55 000 plants per hectare, as optimal for 1.0–2.0 kg market heads.
- Intervention effect Close spacing benefited dry matter, vitamin C and total sugar contents.
- Intervention effect Close spacing decreased nitrate accumulation.
- Intervention effect Increasing N to 300 kg N ha-1 benefited total head yield and yield of heads above 1.0 kg.
- Intervention effect Heavy N fertilization increased nitrate accumulation in cabbage heads.
