nair.turmeric.uniformity: Uniformity trial of turmeric. In agridat: Agricultural Datasets

Description

Uniformity trial of turmeric in India, 1984.

Usage

 `1` ```data("nair.turmeric.uniformity") ```

Format

A data frame with 864 observations on the following 3 variables.

`row`

row ordinate

`col`

column ordinate

`yield`

yield per plot, kg

Details

An experiment conducted at the College of Horticulture, Vellanikkara, India, in 1984. The crop was grown in raised beds.

The gross experimental area was 74.2 m long x 15.2 m wide. Small elevated beds 0.6 m x 1.5 m were raised providing channels of 0.4 m around each bed. One row of beds all around the experiment was discarded to eliminate border effects. After discarding the borders, there were 432 beds in the experiment. At the time of harvest, each bed was divided into equal plots of size .6 m x .75 m, and the yield from each plot was recorded.

Field map on page 64 of Nair.

Field length: 14 plots * .6 m + 13 alleys * .4 m = 13.6 m

Field width: 72 plots * .75 m + 35 alleys * .4 m = 68 m

Data found in the appendix.
