wheatyield {KenSyn}

Wheat Yield at a regional scale (fake data).

Description

Wheat yield. The data set consists of 45 measurements of wheat yields from 15 experimental sites (one year) in a fictive agricultural region. In this dataset, a study represents a site-year with 2 to 4 blocks. Each block corresponds to an experimental plot on which the yield of the crop (expressed in t.ha-1) was measured. Thus, each study contains 2 to 4 measurements of yields
