Abstract

Background and Objective: Water and fertility stress are the most important factors for reducing Sugar Beet Yield in Iran. Since irrigation and Boron Fertilizer have significant effects on Sugar Beet Yield, simulating those factors on Sugar Beet Yield were done using AquaCrop model. Materials & Methods: Treatments were consisted of irrigation management in four periods (I1: 6, I2: 9, I3: 12, and I4: 15 day) and Boron Fertilizer amount in three levels (F0: 21 kg. ha-1, F1: 30 kg. ha-1 and F2: 39 kg. ha-1; as low, medium and appropriate, respectively). Results: Maximum and minimum difference between simulation and observation values for Yield were shown in F2I2 (4. 33 t. ha-1) and F0I4 (0. 37 t. ha-1), respectively. Average difference between simulation and observation value for Yield was 1. 77 t. ha-1. NRMSE (0. 04) and RMSE (2. 24) values showed that AquaCrop had good accuracy for simulating Yield, however, MBE (1. 07) result revealed the model had over estimate error. Criteria results for d and EF showed AquaCrop had good efficiency. RMSE and NRMSE values for Water Use Efficiency were 0. 29 kg. m-3 and 0. 07, respectively. MBE value for mentioned parameter was 0. 17 kg. m-3. Conclusion: Regarding the importance of the effect of main factors on Sugar Beet Yield in sustainable production, it is recommended to use AquaCrop for simulating Sugar Beet Yield.
