ABSTRACT
H.L. Boogaard, A.J.W. De Wit, J.A. te Roller, C.A. Van Diepen, 2014.
WOFOST CONTROL CENTRE 2.1; User’s guide for the WOFOST CONTROL
CENTRE 2.1 and the crop growth simulation model WOFOST 7.1.7.
Wageningen (Netherlands), Alterra, Wageningen University & Research
Centre.
WOFOST version 7.1.7 is a computer model that simulates the growth and
production of annual field crops. All the run options are operational through
a graphical user interface named WOFOST Control Centre version 2.1
(WCC). WCC facilitates selecting the production level, and input data sets on
crop, soil, weather, crop calendar, hydrological field conditions, soil fertility
parameters and the output options. The files with crop, soil and weather
data are explained, as well as the run files and the output files. A general
overview is given of the development and the applications of the model. Its
underlying concepts are discussed briefly.
Keywords: computer model, crop data simulation, crop production,
production ecology, soil data, system analysis, weather data
