Simulation of Yield and Optimization of Water and Nitrogen Consumption for Soybean using AquaCrop Model Mojtaba Khoshravesh Miangoleh E mail address khoshravesh m24@yahoo com Date of Submission January 16 2013 Department of Water Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Behrouz Mostafazadeh Fard1 E mail address behrouz@cc iut ac ir Manouchehr Heidarpour2 E mail address heidar@cc iut ac ir Ali Reza Kiani3 E mail address akiani71@yahoo com Sayed Farhad Mousavi4 E mail address mousavi@cc iut ac ir Abstract On a global scale irrigated agriculture consumes about 72 of available fresh water resources Deficit irrigation can be applied in the field to save irrigation water and still have acceptable crop production Poor soil fertility and erratic rainfall are the major constraints to sustainable agricultural productivity The AquaCrop model is a new model that is accurate robust and requires fewer data inputs compared with the other models The purpose of this study was to sensitivity analysis of AquaCrop model and to simulate grain yield biomass water use efficiency and actual crop evapotranspiration for soybean A field line source sprinkler irrigation system was conducted under full and deficit irrigation using different nitrogen fertilizer applications during two cropping seasons for soybean at Gorgan province in Iran The simulation results showed a reasonably accurate prediction of grain yield and biomass in all cases The simulated pattern of biomass accumulation and grain yield over time was close to measured values with Willmott s index of agreement for all the cases being 0 95 for biomass and grain yield The optimization can be made to determine maximum WUE For example the amount of irrigation water to achieve optimum WUE was equal to 200 and 275 mm for the first and second year of study respectively The ETc was estimated using AquaCrop model and it closely corresponded with the measured values 23 error The simulated soil moisture data can be used in subsequent studies to develop a drought indicator for agricultural drought monitoring AquaCrop model can be valuable tool in water and nitrogen management Keywords AquaCrop model soybean deficit irrigation nitrogen application soil moisture line source water use efficiency 1 Professor Department of Water Engineering College of Agriculture Isfahan University of Technology Isfahan 84156 83111 Iran 2 Professor Department of Water Engineering College of Agriculture Isfahan University of Technology Isfahan 84156 83111 Iran 3 Associate professor Gorgan Agricultural and Natural Resources Research Center Gorgan 41996 13475 Iran 4 Professor Department of Water Engineering College of Agriculture Isfahan University of Technology Isfahan 84156 83111 Iran
