Other claims from this paper (7)
- Observation Predicted maximum watermelon marketable yield was 102 Mg ha −1 at 7.2 kPa and 336 kg N ha −1.
- Observation Predicted maximum net return was $10 819 ha −1 at 10.2 kPa and 256 kg applied N ha −1.
- Observation The combined response was optimal at 12.6 kPa and 178 kg N ha −1.
- Observation The combined response stayed within 95% of maximum across 10 to 16 kPa and 60 to 300 kg applied N ha −1.
- Observation At 7 to 17 kPa and 60 to 315 kg applied N ha −1, predicted yield and net return exceeded 95% of their maxima.
- Observation At 7 to 17 kPa and 60 to 315 kg applied N ha −1, calculated drainage nitrate concentration remained below 10 mg NO − 3 ‐N L −1.
- Method / resource Data normalization and spatial analysis were useful for concurrent evaluation of watermelon production criteria.
