Crop growth model for potential production. SUCROS1 is a mechanistic crop growth model as influenced by environmental conditions. SUCROS1 simulates potential growth of a crop, i.e. its dry matter accumulation under ample supply of water and nutrients in a pest-, disease- and weed-free environment under the prevailing weather conditions. The rate of dry matter accumulation is a function of irradiation, temperature and crop characteristics. The basis for the calculation is the rate of CO2 assimilation (photosynthesis) of the canopy; it is a function of incoming radiation and light. After substraction of maintenance respiration, growth of leaf, stem, root and storage organs are simulated. Biomass partitioning depends on crop development stage, which is computed as a function of temperature only. With crop specific input parameters different crops can be simulated.
