Interpretive Summary: From 1992-1997, ARS researchers from the U.S. Water Conservation Laboratory, Phoenix, AZ (now moved to U.S. Arid-Land Agricultural Research Center, Maricopa, AZ) conducted four FACE (free-air CO2 enrichment) experiments on wheat at ample and limiting levels of water and nitrogen. More than 50 scientists from the U.S. and 7 other countries participated. Since then, data from these experiments have been requested numerous times for subsequent modeling and meta-analytic studies about the likely effects of global climate change on future wheat productivity. Therefore, this manuscript, along with 21 associated data files, have been assembled for publication in an “open” data journal so that anyone in the future will have easy access to this valuable dataset. The dataset is comprehensive and includes management, soils, weather, physiology, phenology, growth, yield, baking quality, and other data. This research will benefit all consumers of wheat-based food, including meat from animals that are fed wheat.

Technical Abstract: Four free-air CO2 enrichment (FACE) experiments were conducted on wheat (Triticum aestivum L. cv. Yecora Rojo) at Maricopa, Arizona, U.S.A. from December, 1992 through May, 1997. The first two were conducted at ample and limited (50% of ample) supplies of water, and second two at ample (350 kg N ha-1) and limited (70 and 15 kg N ha-1) supplies of fertilizer nitrogen. More than 50 scientists participated, and they collected a large and varied set of data on plant, soil, and microclimatic responses to the elevated CO2 and its interactions with the water and N treatments. The dataset has been popular with wheat growth modelers who have utilized the growth, yield, and other data to validate their models, which get used to predict likely future wheat productivity with projected global climate change. The dataset assembled herein contains many of these data, including management, soils, weather, physiology, phenology, biomass growth, leaf area, yield, quality, canopy temperatures, energy balance, soil moisture, nitrogen assimilation, and other data.
