Simulation of wheat yield by AquaCrop model
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 21
Abstract
Crops growth simulation models are important tools for evaluating effects of water deficiency on productivity and yield of crops. One of these models is the AquaCrop model. This model can simulate productivity, yield, water requirement and water use efficiency under condition of water limitation. This research was carried out in order to simulation of some parameters of crops growth under condition of different water regimes on wheat in Sistan region at 2012-13. In this research climate, soil characteristics, plant characteristics and crop cultivation management are from major inputs for model. Place situation, climatic data, soil data, management data are necessary data and information for running model of AquaCrop. The simulation results showed that model simulates biomass and seed yield well. But this model couldn’t simulate water use efficiency (WUE) optimally. So that for biomass yield, seed yield and water use efficiency obtained RMSEn and R2 equal to (3.20% and 0.99), (5.90% and 0.99) and (16.2% and 0.91) respectively.
