Brassica Experiment

Researcher

Alan Miller, U WI Horticulture

Description

The scientist examined the effects of rate of application of a certain herbicide (pyridate) on a range of closely related crops. The experiment was conducted over two years, with three blocks each year. The two years were conducted in roughly the same location, but there was separate randomization in each year. Three herbicide rates (pyrrat = 0, 1, 2) were randomly assigned to separate rows within each crop plot. Recorded values consist of yield per row for each crop*pyrrat combination within each block for each year. Since crop 2 was not used in the second year, it is dropped from further consideration.
