## Mildew control

### Description

The data refer to study of mildew control sponsored by Bainbridge, Jenkyn and Dyke at Rothamsted Experimental Station. There were four treatments, one of which was a control. There were 36 adjacent plots, with an extra plot at each end. Nine blocks were created by grouping the plots in fours.

The variables are:

`t1, t2, t3` | indicators of the four treatment groups
`p1, ..., p8` | indicators of the nine blocks
`Yield` | tons of grain per hectare
