Method / resource AtLeaf measurements explained 53.3% of wheat grain yield variation.
Method / resource GreenSeeker measurements explained 68.5% of wheat nitrogen uptake variation.
Method / resource AtLeaf prediction fits for nitrogen uptake and grain yield were fair on independent wheat data.
Method / resource GreenSeeker prediction fits for wheat nitrogen uptake and grain yield were good on independent data.
Recommendation The authors conclude both sensors can support site specific nitrogen management in wheat.
