Description	The dataset contains experimental data on maize growth for crop model calibration, at five sites in sub-Saharan Africa. The observed climate data for the experimental years at the sites is provided, along with basic soil characteristics. Crop management (planting date, date of field operations) is also described, as welll as initial conditions prior to planting. Eventually, observations of in-season leaf area index (when available), soil water (and N when available), aboveground biomass and grain yield are harvest are provided. (2025)
