Trial Information

South Dakota

Webster

Planting Date: April 29
Previous Crop: Wheat
Seed Rate: 17 viable seeds/ft2
Seed Treatment: None except as sent
Soil Type:
Soil Test:
Fertilizer Applied: Nitrogen
Yield Goal:
Row Spacing: 7 inches
Harvest Date: Varied

General Observations:
Stands were variable due to crusting and possibly some insect damage. Uneven emergence made it difficult to take flowering and maturity notes, so only days to 10% flower are reported. There was hail damage on June 19th. The Polish varieties were more damaged than the Argentine, as they were nearing the completion of flowering when the hail occurred. Seed yields were adjusted for % stand by covariance analysis.

Watertown

Planting Date: April 29
Previous Crop:
Seeding Rate: 17 viable seeds/ft2
Seed Treatment: None except as sent
Soil Type:
Soil Test:
Fertilizer Applied: Nitrogen
Yield Goal:
Row Spacing: 7 inches
Harvest Date: Varied

General Observations:
Good stands, adequate precipitation. Temperatures warmer than normal in April and May, cooler than normal June to August.

Minnesota

Roseau

Planting Date: April 30
Previous Crop: Wheat 1995, 96, 97
Seeding Rate: 12 viable seeds/ft2
Seed Treatment: Gaucho and Benlate
Soil Type: Sandy clay loam
Soil Test: 74-14-230-17 N-P-K-S
Fertilizer Applied: 85-50-40-20 N-P-K-S
Yield Goal: 2400 lbs/a
Row Spacing: 6 inch - 10 rows
Harvest Date: August 10,14, 20

General Observations:
The Roseau location looked good this year considering the amount of stress.  First, quackgrass and Canada thistle patches
needed to be controlled with herbicides early in the season. Secondly, the weather in June was very cold and wet. Yields were lower than expected at the Roseau location, mostly due to the wet conditions.

Crookston
Planting Date: April 24
Previous Crop: Wheat
Seeding Rate: 12 viable seeds/ft2
Seed Treatment: Gaucho and Benlate
Soil Type: Clay loam
Soil Test: 65-38-260-66; N-P-K-S
Fertilizer Applied: 80-25-0-15; N-P-K-S in the fall
Yield Goal: 2400 lbs/a
Row Spacing: 6 inch -10 rows
Harvest Date: August 7, 12, 19

General Observations:
The Crookston location looked good throughout the season and achieved very good yields. The site was planted into relatively dry conditions, which resulted in two emergence times about a week apart. Flower notes were taken on the first emergence. However, by the end of the season, there was little distinguishable difference in maturity within the plot.

Kennedy

Planting Date: April 24
Previous Crop: Wheat
Seeding Rate: 12 viable seeds/ft2
Seed Treatment: Gaucho and Benlate
Soil Type: Clay loam
Soil Test: 63-4-317-360; N-P-K-S
Fertilizer Applied: 80-0-0-15 Fall N-P-K-S; 0-16-0-0 Spring
Yield Goal: 2200 lbs/a
Row Spacing: 6 inch -10 rows
Harvest Date: September 5, 12, 20

General Observations:
The Kennedy location looked good this year. While end trimming the plots early in the season with Roundup, some of the chemical drifted onto the plots. Some plants on the ends of the plots were injured. Injury notes were taken about a week after end trimming and again at swathing time. Plots with injured plants on the edges of the plot were shortened to remove the injury, and plots with more than 1/3 of the plot damaged were not used for yield data. Thus, with these adjustments, yield data should still be representative for each variety. All other notes were taken from the uninjured portions of the plots. Modifications to the sprayer are planned for this winter to avoid future problems with drift.

Kennedy - Roundup Ready

Planting Date: April 28
Previous Crop: Wheat
Seeding Rate: 12 viable seeds/ft2
Seed Treatment: Gaucho and Benlate
Soil Type: Clay loam
Soil Test: None taken
Fertilizer Applied: 14-0-0-90-30-0-15
Yield Goal: 2200 lbs/a
Row Spacing: 6 inch -10 rows
Harvest Date: August 5, 20

General Observations
The site was seeded into dry conditions with heavy wheat residue. Timely rains provided for even emergence. Some pod abortion was observed midway through the season from hot dry conditions.

Fosston

Planting Date: May 4
Previous Crop: Wheat
Seeding Rate: 12 viable seeds/ft2
Seed Treatment: Gaucho and Benlate
Soil Type: Clay loam
Soil Test: 30-8-128-6; N-P-K-S
Fertilizer Applied: 80-30-30-20; N-P-K-S in the spring
Yield Goal: 2000 lbs/a
Row Spacing: 6 inch -10 rows
Harvest Date: August 14, 21

General Observations:
The Fosston location looked good this year. The plants were just emerging at this site when a heavy thunderstorm came through the area and caused a lot of soil to wash into the press wheel markings and cover some of the cotyledons. This resulted in a decreased stand for replicates 1 and 3, which were in the lower area of the site. Stand reductions appeared uniform within each replicate. The reduced stands did not appear to affect yield as the canola plants branched to fill the gaps.

No weather data available for Fosston.

Fosston - Liberty Link

Planting Date: May 5, 1998
Seeding Rate: 12 viable seeds per square foot
Previous Crop: '97 wheat

Morris

Planting Date: April 30, 1998
Seeding Rate: 12 viable seeds per square foot
Previous Crop: '97 wheat
Seed Treatment: Goucho and Benlate
Soil Type: Silt Loam
Soil Test: all #/A None taken
Fertilizer Applied: 120-46-60-0; N-P-K-S
Yield Goal: 2000 lbs/A
Row Spacing: 7 inch - 8 rows
Harvest Dates: August 11

General Trial observations:
The Morris location looked good this year with good emergence and good growth. A miscommunication at planting resulted in only 5' alleyways, which did not allow for swathing all the varieties at the optimum time. To keep from losing the early varieties to shattering, some of the late maturing varieties were swathed before physiological maturity. Seven varieties were discarded due to being swathed too early. These include LA 161, LA 269, Global, CL 2070, CL 2078, Oscar and Crusher. The performance of these varieties is not reported and the companies that submitted them will receive credit for testing at Morris in 1999

Hettinger

Planting Date: April 14 and 28
Previous Crop: Fallow
Seed Treatment: Furadan CR-10
Seeding Rate: 7.5 lbs/a B.napus and 4.5 lbs/a B.rapa
Soil Type: Silty loam
Soil Test: 108-56-1050-S198
Fertilizer Applied: 100 lbs/a gypsum
Yield Goal: 2000 lbs/a
Row Spacing: 7 inches
Harvest Date: July 31

General Observations:
The trial was split into two trials due to the fact that that all the seed was not received before the optimum planting time. Rather than risk the entire trial, the seed on hand on April 14 was planted and the remaining entries were seeded two weeks later. Early season growing conditions were almost ideal with mild temperatures and adequate moisture. An unusual killing frost occurred on June 3. The Polish varieties were in full bloom and most other varieties were just beginning to initiate flowering. As the season progressed, hot and dry conditions set in causing lower test weights and reduced yield, especially late planted varieties.

Carrington

Planting Date: April 29
Previous Crop: Winter Rye
Seeding Rate: 17 PLS/ft2
Seed Treatment: Furadan CR10 to non-Gaucho treated entries
Soil Type: Heimdahl silt loam
Soil Test: 50 lbs/a, 20 ppm, 340 ppm, 8 ppm, N-P-K-S
Fertilizer Applied: 100 lbs/a N + 125 lbs/a ammonium sulfate
Yield Goal: 2500 lbs/a
Row Spacing: 7 inches
Harvest Date: July 20 - August 10

General Observations:
Excellent stand establishment (uniform and fairly quick). Slightly longer than normal vegetative growth period followed by somewhat short blooming period. No rain from July 4 to harvest. At physiological maturity plants turned from green to tan very quickly. Pod wall color was not necessarily indicative of seed color.

Prosper

Planting Date: May 21
Previous Crop:
Seeding Rate: Varied with species
Seed Treatment:
Soil Type: Gardena-Glyndon silt loam
Soil Test:
Fertilizer Applied: to a 60 bu/a wheat yield

Langdon

Planting Date: May 12
Previous Crop: Fallow
Seeding Rate: 17 PLS/ft2
Seed Treatment: Furadan CR-10, Benlate
Soil Type: Svea loam
Soil Test: 116-17-270-125S
Fertilizer Applied: 24-30-40-20 N-P-K-S lbs/a
Yield Goal: 2200 lbs/a
Row Spacing: 6 inches
Harvest Date: Varied August 27 - September 2

General Observations:
Two days after the trial was seeded 3.34 inches of rainfall was received. A crust developed and caused some stand reductions. Visual stand ratings were recorded. There were a few varieties that had poor stands in all replications indicating that they do not perform very well under a crusting condition. Varieties with poor stands tended to have lower yields but not in all instances which suggests that some varieties have the ability to compensate in low stand situations better than other varieties.

Row Spacing: 6 inches
Harvest Date: September 26

General Observations:
The seedbed was quite dry when planting, and emergence was very uneven. Notes taken from each plot indicated an average of only 38% of the plots emerged from the first flush. Adequate rainfall to germinate the remaining seeds did not fall until the third week of June. After this time stands from the entire plot were good but there were big differences in growth stages. These differences were not as evident at harvest. Because of the uneven development, notes on flowering and maturity were not taken.
