Uniformity trials of pole beans, bush beans, sweet corn, carrots, spring and fall cauliflower

Uniformity trials of pole beans, bush beans, sweet corn, carrots, spring and fall cauliflower at Washington, 1952-1955.

Format

Each data frame has the following columns at a minimum. Some datasets have an additional trait column.

row: row
col: column
yield: yield (pounds)

Details

All trials were grown on sandy loam soil in the Puyallup valley of Washington. In most experiments a gradient in soil fertility was evident. Moore & Darroch appear to have assigned 4 treatments to the plots and used the residual variation to calculate a CV. In the examples below a 'raw' CV is calculated and is always higher than the CV given by Moore & Darroch.

Blue Lake Pole Beans.

Conducted 1952. Seven pickings were made at about 5-day intervals. Table 26.

Field width: 12 rows x 5 feet = 60 feet.

Field length: 12 ranges x 10 feet = 120 feet.

Bush Beans.

Conducted in 1955. Two harvests. Table 27.

Field width: 24 rows x 3 feet = 72 feet.

Field length: 24 ranges x 5 feet = 120 feet.

Sweet Corn.

Conducted 1952. Table 28-29.

Field width: 24 rows x 3 feet = 72 feet.

Field length: 12 ranges x 10 feet = 120 feet.

Carrot.

Conducted 1952. Table 30.

Field width: 24 rows * 1.5 feet = 36 feet.

Field length: 12 ranges * 5 feet = 60 feet.

Spring Cauliflower.

Conducted spring 1951. Five harvests. Table 31-32.

Field width: 12 rows x 3 feet = 36 feet.

Field length: 10 plants * 1.5 feet * 20 ranges = 300 feet.

Fall Cauliflower.

Conducted fall 1951. Five harvests. Table 33-34.

Field width: 12 rows x 3 feet = 36 feet.

Field length: 10 plants * 1.5 feet * 20 ranges = 300 feet.
