Highlights • Variation in yield-nitrogen responses explored using long-term experiments (LTEs).• Yield-nitrogen relationship modelled using linear-plus-exponential function.• Inter-annual variation in parameters explained using monthly weather summaries.• Modelling allows separation of effects of environmental and agronomic factors.• Selected monthly weather variables associated with key crop development processes.
