Uniformity trial of tomato in India

Usage

data("shafi.tomato.uniformity")

Format

A data frame with 200 observations on the following 3 variables.

row

row ordinate

col

column ordinate

yield

yield, kg/plot

Details

The experiment was conducted at the Regional Research Station Faculty of Agriculture, SKUAST-K Wadura Campus during 2006.

The original data was collected on 1m x 1m plots. The data here are aggregated 2m x 2m plots.

Field length: 20 row * 2 m = 40 m

Field width: 10 col * 2 m = 20 m
