Other claims from this paper (8)
- Association Dualex NBI was linearly related to leaf total N concentration.
- Method / resource The NBI relationship enabled derivation of a nonlinear NBI–biomass critical curve.
- Method / resource For biomass ≥1 Mg ha−1, the curve correctly classified 92% of non-deficit treatments.
- Method / resource For biomass ≥1 Mg ha−1, the curve correctly classified 79% of deficit treatments.
- Method / resource Proposed NBI sufficiency was 34–36 at about 1 Mg ha−1 and about 50% ground cover.
- Method / resource Proposed NBI sufficiency was 31–33 at about 2 Mg ha−1 and button stage.
- Method / resource Proposed NBI sufficiency was 27–29 at about 4 Mg ha−1 and pre-harvest.
- Recommendation The authors conclude Dualex NBI can support in-season cauliflower nitrogen management with less destructive sampling.
