Other claims from this paper (11)
- Observation Sugar-yield responses averaged low.
- Observation 0·6 cwt. N/acre supplied virtually all nitrogen for maximum sugar production.
- Intervention effect The heavier nitrogen dressing substantially increased top yield.
- Intervention effect Calcium nitrate matched ammonium sulphate for sugar-yield increase.
- Intervention effect Urea matched ammonium sulphate for sugar-yield increase.
- Observation No fertilizer damaged germination.
- Observation Topdressing with urea containing 4·5% biuret showed no damage.
- Intervention effect Calcium nitrate produced more tops than ammonium sulphate.
- Intervention effect Urea produced more tops than ammonium sulphate, to a lesser extent than calcium nitrate.
- Intervention effect All seedbed nitrogen matched a split dressing for sugar yield.
- Mechanism Wet-summer nitrogen leaching was judged unimportant for sugar beet.
