TL;DR: The authors systematically tested 30 different wheat crop models of the Agricultural Model Intercomparison and Improvement Project against field experiments in which growing season mean temperatures ranged from 15 degrees C to 32 degrees C, including experiments with artificial heating.

TL;DR: This work defines key criteria, experimental approaches, equipment and data analysis tools required for robust, high-throughput field-based phenotyping (FBP), and focuses on simultaneous proximal sensing for spectral reflectance, canopy temperature, and plant architecture.
Journal ArticleDOI
Methodologies for simulating impacts of climate change on crop production
TL;DR: In this paper, the authors reviewed 221 peer-reviewed papers that used crop simulation models to examine diverse aspects of how climate change might affect agricultural systems, focusing on wheat, maize, soybean and rice.
Journal ArticleDOI
Productivity and water use of wheat under free‐air CO2 enrichment

TL;DR: A free-air CO2 enrichment (FACE) experiment was conducted at Maricopa, Arizona, on wheat from December 1992 through May 1993 as mentioned in this paper, where the FACE apparatus maintained the CO2 concentration, [CO2], at 550 μmol mol−1 across four replicate 25m-diameter circular plots under natural conditions in an open field.

TL;DR: This paper showed that grid-based and point-based simulations and statistical regressions, without deliberate adaptation or CO 2 fertilization effects, produce similar estimates of temperature impact on wheat yields at global and national scales.
