Field experimental data for crop modeling of wheat growth response to nitrogen fertilizer, elevated CO2, water stress, and high temperature

Field experimental data of five experiments covering a wide range of growing conditions are assembled for wheat growth and cropping systems modeling. The data include (i) an experiment on interactive effects of elevated CO2 by water and elevated CO2 by nitrogen fertilizer application from a Free-Air Carbon Dioxide Enrichment experiment (FACE) at Arizona in USA; (ii) a nitrogen rate fertilizer experiment from three locations and two years in The Netherlands; (iii) water deficit experiments at Lincoln in New Zealand and (iv) at Cunderdin in Australia; and (v) a temperature sensitivity experiment at Obregon in Mexico. Overall, the data sets consist of 65 experimental treatments with more than 1000 observations, with time series of development and growth, soil water and soil nitrogen dynamics, yield and yield components, daily weather, soil characteristics, and cultivar descriptions. These data have been used in various agronomic and crop modeling studies.
