- Method / resource A unary non-structural fertilizer response model was proposed.
- Method / resource New models significantly predicted rice yields in 18 field experiments.
- Method / resource Two unary QPFM fits did not pass statistical significance tests.
- Method / resource Residual standard deviations of 13 new models were significantly lower than unary QPFM.
- Association Recommended application rates from the new model and QPFM had a significant linear correlation.
- Method / resource Theoretical analysis identified unary QPFM as a simplified version of the new model.
- Method / resource Theoretical analysis reported higher fitting precision and better applicability, with the model referent ambiguous.
