It should be noted that data used in (A) and (B) panels are from different experimental treatments under both rainfed and irrigated conditions of main producing areas of that crop in Iran and are not necessary potential yield.

Wheat:

Simulated versus observed yields from data used in model parameterization (A) and evaluation (B), simulated potential yield versus reported irrigated potential yield (C), simulated versus observed cumulative irrigation water or evapotranspiration (D) and simulated potential yield versus reported rainfed potential yield. 

 

Barley:

Simulated versus observed yields from data used in model parameterization (A) and evaluation (B), simulated potential yield versus reported potential yield (C). In (C), potential yields reported for different locations are compared with minimum, average and maximum potential yield for the same locations over 15 years.

Rice:

Simulated versus observed yields from data used in model parameterization (A) and evaluation (B), simulated potential yield versus reported irrigated potential yield (C), simulated versus observed cumulative irrigation water (D).

High yield: new high yield cultivars

Low yield: local low yield cultivars  

Maize:

Simulated versus observed yields from data used in model parameterization (A) and evaluation (B), and simulated potential yield versus reported irrigated potential yield (C).  In (C), potential yields reported for different locations are compared with minimum, average and maximum potential yield for the same locations over 15 years.

Chickpea:

Simulated versus observed yields from data used in model parameterization (A) and evaluation (B), simulated potential yield versus reported rainfed  potential yield (C).  In (C), potential yields reported for different locations are compared with minimum, average and maximum potential yield for the same locations over 15 years.
