WOFOST ====== WOFOST is a computer model that simulates growth and development of annual field crops (`de Wit et al., 2019 `_). It can be used to estimate potential crop productivity for a given variety, and under specified soil and weather conditions. Such estimates are the basis for the analysis of variability and trends in crop yields, benefits of new agricultural technology (varieties in particular), and for understanding options for regional agricultural production. In this subsections we first briefly describe some of the the `concepts `_ on which the model is based. In the second chapter we show an `example model run `_. The following chapters describe the model input: `weather data `_ and parameters defining the `soil `_ `crop `_, and crop `management `_ in detail. Then there is a chapter that describes how to manipulate the `model `_ object. The last chapter discusses the model `output `_. .. toctree:: :hidden: background example weather crop soil control model output
