Abstract: Uncertainty exists as to the optimum whole-farm irrigation strategy for wheat growing in subtropical Australia under water-limited conditions. While deficit irrigation has been shown to have greater economic water productivity (EWP) in such circumstances in other regions, there are limitations to the cost/revenue function approach traditionally used to evaluate EWP, including inapplicability across environments. These limitations can however be overcome with the use of a validated cropping systems model.
