Nowadays, due to the population growing and agriculture lands degradation, optimum land use and management become essential. Consequently land suitability evaluation and prediction of the production potential are important processes. The goal of the present research is the comparison of AEZ and Wageningen models in estimation of the Thermal-Radiation production that it is one of parameters in calculation of the Production Potential in FAO method for irrigated wheat. Soil morphological, physical and chemical characteristics of 10 land units of Khajeh region with 1100 ha extension located in East Azarbaijan province were selected. The soils of the study region have Aridic border to xeric moisture and mesic temperature regimes, and were classified in Aridisols orders according to keys to soil taxonomy 2014. Coefficient of correlation values between land production potential and observed yield were 0.74 and 0.72 for AEZ and Wageningen models respectively. Geometric mean error ratio (GMER) index was used for studying the model accuracy. The values of this index have been calculated for the AEZ and wageningen models 1.02 and 2.28 respectively. According to the coincidence of agreement maps of the AEZ or wageningen models and observed yield the agreement in AEZ method 52.8 % is more than of the Wageningen method 12.8%. Finally, the AEZ model is more efficient than the other because it has high precision, accuracy, overall map agreement with observed yield and low calculating process.
