Ground-level, hyperspectral and thermal remote data from wheat genotypes grow under various combinations of water and nitrogen availability

In this data we provide different agronomic variables and sensor readings (reflectance spectra and canopy temperature) from an agricultural crop rotation under Mediterranean conditions. The data were obtained in Central Spain after collecting plant samples in a field experiment during two growing seasons: 2018-2020 and 2019-2021. These variables represent the crop response of two wheat (Triticum aestivum L.) genotypes to different precedent crops (legume versus non-legume), nitrogen fertilization and water levels, as well as the readings of leaf-clip and proximal sensors in different growth stages.
+ Value of the data:
Data relating agronomic and sensor information from different wheat genotypes under nitrogen and water interactions will be useful for understanding crop performance and optimizing irrigation and nitrogen fertilization.
The present dataset could help researchers and farmers to identify suitable genotypes and their responses to nitrogen and water stress.
+ Detailed description:
The file ‘Grain yield, GNC and N output of wheat.xlsx’ contains the specific year in which each sample was taken is indicated in the database, the dry biomass (kg ha-1), carbon and nitrogen concentration (% C and %N), C/N ratio and N uptake (kg N ha-1) measured in wheat at flowering in the different treatments every year (Wheat Biomass.xlsx). In addition, the dataset contains the wheat grain yield (kg ha-1), % C, % N, C/N ratio and N output (kg N ha-1) at harvest in the two years were recorded.
The files ‘Dualex readings.xlsx’ and ‘Greeseeker readings.xlsx’ contains the chlorophyll (Chl), flavonoid (Flav), anthocyanin (Anth) content and the nitrogen balance index (NBI, calculated as the ratio Chl/Flav) measured with the leaf-clip sensor Dualex®, and the normalized difference vegetation index (NDVI) taken with the proximal sensor GreenSeeker® at three different growth stages (GS) for all genotypes and treatments.
The file ‘Reflectance of wheat.xlsx’ contains the hyperspectral wheat reflectance measured at five GS in all treatments.
The file ‘Thermal data of wheat.xlsx’ contains the canopy temperature acquired at three GS in all treatments. Additionally, dry and wet bare soil temperature was measured as well as the air temperature.
