This report describes standardized data for “26th Semi-Arid Wheat Yield Trial”. These data were standardized on 2023-06-30 by Robert Hijmans with this R script. The original data have a CIMMYT license. Because of the restrictions of this license, you need to run the script yourself to get the standardized data.
