Other claims from this paper (7)
- Observation Sugar beet varieties and breeding lines differed in fertilizer responses in preliminary experiments.
- Intervention effect An application of 75 kg N/ha increased sugar yield similarly across the varieties.
- Intervention effect A further 75 kg N/ha did not change mean sugar yield of any variety across the three experiments.
- Observation Sodium yield response was greatest in Sharpe's Klein ‘E’ and least in V.T.137.
- Observation Potassium yield response was greatest in Sharpe's Klein ‘E’ and least in V.T.137.
- Observation Varietal responses to nitrogen, sodium and potassium varied inconsistently across years.
- Observation Pooled fertilizer-by-variety interactions were not statistically significant.
