Datasets from books, papers, and websites related to agriculture. Example graphics and analyses are included. Data come from small-plot trials, multi-environment trials, uniformity trials, yield monitors, and more.
The purpose of agridat is to provide a single R package which collects
datasets from agricultural experiments.
