Verbatim
e0“Nitrogen (N) uptake by sugarbeets ( Beta vulgaris L.) from fertilizer and soil”
e1“was evaluated at Davis, California, in two field experiments”
e2“There were no significant differences in root, top, or sugar yield when fertilizer N (135 kg/ha) was applied at planting, at thinning, split equally between thinning and layby, or split equally between planting, thinning, and layby”

Other claims from this paper (6)
- Intervention effect Dates of fertilizer N application did not substantially change soil or fertilizer N in sugarbeet tops and roots.
- Observation Fertilizer N recovery in sugarbeet was 47% when 112 kg N/ha was applied for maximum sugar yield.
- Observation Sugarbeet roots removed as much N as was applied.
- Observation Sugarbeet tops contained an additional 105 kg N/ha.
- Observation When applied N was 2.5 times the amount for maximum sugar yield, sugarbeet tops and roots contained almost as much N as applied.
- Recommendation Carefully fertilized sugarbeet has potential for alleviating nitrate pollution of ground water.
