Other claims from this paper (11)
- Intervention effect In-season nitrogen increased total nitrogen uptake.
- Intervention effect In-season nitrogen increased tuber nitrogen concentration.
- Intervention effect In-season nitrogen reduced dry matter partitioning to tubers.
- Intervention effect In-season nitrogen reduced nitrogen partitioning to tubers.
- Intervention effect Yield gains were most consistent between 277 and 295 kg N ha − 1.
- Intervention effect Nitrogen beyond that range gave no additional yield benefit.
- Method / resource The quadratic model best described total yield.
- Method / resource The linear-plateau model best described marketable yield.
- Method / resource Relative yield normalization improved model accuracy across years.
- Recommendation The authors support site- and cultivar-specific nitrogen recommendations using models.
- Recommendation The authors call for broader multi-environment datasets to refine predictive models.
