Other claims from this paper (6)
- Association Chlorophyll meter readings and tissue nitrogen had a positive linear relationship on most July and August dates.
- Observation Regression coefficients varied between sampling dates.
- Method / resource Days after planting and chlorophyll meter readings explained 84% of tissue nitrogen variability.
- Association Chlorophyll meter readings were highly correlated with final crop yield.
- Association Tissue nitrogen was highly correlated with final crop yield.
- Recommendation The authors suggest a chlorophyll meter reading of 52 at anthesis to prevent yield reductions.
