Crop growth model for water-limited conditions. SUCROS2 describes crop growth (as applied to spring wheat) under water-limited conditions by including water balances of crop and soil in the SUCROS1 model. Conditions of other growth factors are supposed to be optimal, i.e. ample nutrients and a pest-, disease- and weed-free environment. With the SUCROS2 model, options for soil and water conservation can be studied. The crop/soil water balances in SUCROS2 are based on earlier versions documented by Stroosnijder (1982) and Penning de Vries et al. (1989). SUCROS2 can only be understood on the basis of SUCROS1, the crop growth model for potential production. The effect drought-stress is transmitted through two variables, one acting on daily gross CO2 assimilation and the other one acting on root-shoot partitioning.
