## Oats variety-nitrogen factorial study

### Description

Yield of oats with four fertilizer treatments. The yield of oats from a split-plot field trial with 3 varieties and 4 levels of nitrogen fertilizer. The experiment was a split-plot with 6 blocks of 3 main plots (varieties), each split into 4 sub-plots (nitrogen).

### Usage

    oats

### Format

A data frame with 9 columns and 72 rows:

- Blocks: Complete field replicates, factor with 6 levels

- Nitrogen: Nitrogen application, factor with 4 levels

- Subplots: Sub-plot within whole-plots; factor with 4 levels

- Variety: Variety names, factor with 3 levels

- Wplots: Whole-plots; factor with 3 levels

- yield: Grain yield (in 1/4 lbs.)

- Column: Field column index factor

- Row: Field row index factor

- nrate: Numeric nitrogen rates
