Spring barley calibration data set

The dataset contains detailed above- and below-ground field trial data collected at different Danish sites during two crop-growing seasons (2019 and 2020). The field experiments were designed to study the nitrogen use efficiency of modern two-row spring barley cultivars. The data collected aims to facilitate the calibration of crop models, by providing information on plant development, biomass production, nitrogen uptake and leaf area development from six nitrogen levels.
