Crop growth simulation model is an effective tool for providing decision on agricultural resource management.WOFOST(World Food Studies) was established on the framework of interdisciplinary studies by the Center for World Food Studies in cooperation with the Wageningen Agricultural University.WOFOST estimates the growth of an annual crop given a set of specific soil and weather conditions.The simulation of crop growth is based on physiological processes.Current literatures revealed that WOFOST could be applied in wide zone,including Europe,Africa,Asia.etc.many annual crops have been simulated well,such as rice and maiz.WOFOST has been applied as a tool for the analysis of yield risk, yield variability over soil types,sowing strategies,effects of climate change,critical periods for use of agricultural machinery,and so on.The model has also been used for predicitive purposes,such as regional assessments of crop yield potential in the form of maximum yield levels,estimation of maximum benefits from irrigation or from fertilizer use,detection of adverse growing conditions by simulation-monitoring the agricultural season,and regional yield forecasts as well.
