Evaluation of the CropSyst model in wheat

Abstract

CropSyst is the crop growth model chosen as a decision tool for the Tadla Benchmark project. CropSyst is a daily time step simulation model. The model was developed to serve as an analytic tool to study the effect of cropping systems management on productivity and the environment. The model simulates the soil water budget, soil– plant nitrogen budget, crop canopy and root growth, dry matter production, yield, residue production, and decomposition. Management options include cultivar selection, crop rotation, irrigation, nitrogen fertilization, tillage operations, and residue management. Simulation parameter organization is based on separate component input files for location, soil, crop, and management data. The simulation control file is built up by combining these component files. The objective of this study was to evaluate the CropSyst model under the conditions of the Tadla region.
