Other claims from this paper (11)

Intervention effect Nitrogen rate and spacing interacted in their effects on days to maturity.
Intervention effect Nitrogen rate and spacing interacted in their effects on plant height.
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%.
