Abstract:

The model simulates 2 spring barley varieties with densities NPL, competing for light in a potential production environment. The model is based on the SUCROS* spring wheat model. It has been extended for light interception and distribution within the heterogeneous crop. The model may be applied in plant breeding and crop science.
