- Intervention effect Nitrogen rate and spacing interacted in their effects on days to maturity.
- Intervention effect The main nitrogen effect significantly affected most studied parameters.
- Intervention effect Spacing affected onion leaf number.
- Intervention effect Spacing affected onion yield.
- Intervention effect Increasing nitrogen rate prolonged onion days to maturity.
- Intervention effect Increasing nitrogen from nil to 150 kg N ha -1 decreased bolting by 62%.
- Intervention effect Increasing nitrogen from 50 to 100 kg N ha -1 increased total bulb yield by about 26.7%.
- Intervention effect Increasing nitrogen from 50 to 100 kg N ha -1 increased leaf number by about 29%.
- Intervention effect Increasing nitrogen from 100 to 150 kg N ha -1 tended to decrease total bulb yield by 5.3%.
- Observation The higher marketable yield at 100 kg N ha .-1 was 31.455t ha -1.
- Recommendation The budget analysis identified 100 kg N ha -1 with 6 cm spacing as the best treatment for bulb yield and economic benefit under Shire conditions.
