The Mosicas model is a simple crop model adapted to annual or semi-perenial giant C4 crops. The model simulates the crop growth in biomass influenced by soil water balance and air temperature. According to plant parameters defining if the crop is harvest for the first time or if it’s a regrowth after harvest, the model simulate a daily growth of the leaf area index. Intercepted radiation are then converted to dry mass accumulation through the radiation use efficiency. Carbon is partitioned into various compartments: roots, leaves, stem and eventually sugar reserve. Necessary weather data includes daily temperature, precipitation, global radiations and evapotranspiration. Necessary soil data includes the soil water holding capacity and an estimation of soil depth.
