Trial Information


South Dakota

Webster
Planting Date: April 29
Previous Crop:
Seed Rate: 17 viable seeds/ft2
Seed Treatment: Furadan CR-10
Soil Type:
Soil Test:
Fertilizer Applied: 100 lbs/a N
Yield Goal:
Row Spacing: 7 inches
Harvest Date: August 13-September 3
General Observations:
Stands were generally good but the plants seemed shorter in height than normal. The fourth replication showed considerable green regrowth as the plants should have been maturing, possibly due to herbicide drift from the surrounding soybean field. The fourth replication was therefore excluded from the data analysis.


Watertown
Planting Date: May 6
Previous Crop:
Seeding Rate: 17 viable seeds/ft2
Seed Treatment: Furadan CR-10
Soil Type:
Soil Test:
Fertilizer Applied: 100 lbs/a N, 30 lbs/a P
Yield Goal:
Row Spacing: 7 inches
Harvest Date: August 13-September 3
General Observations:
The trial received virtually no rain for more than 1 ½ months after it was planted, causing reduced emergence. Stands were very variable, ranging from 10% to 80% on a plot basis. A covariance analysis was used to adjust plot yields for stand.


Minnesota


Roseau
Planting Date: May 28
Previous Crop: Barley
Seeding Rate: 12 viable seeds/ft2
Seed Treatment: Furadan CR-10, Benlate
Soil Type: Sandy clay loam
Soil Test:
Fertilizer Applied: 29-40-30-20 N-P-K-S; plus 130 N fall anhydrous
Yield Goal: 2200 lbs/a
Row Spacing: 6 inch - 10 rows
Harvest Date: September 5,10, 23
General Observations:
The Roseau site looked very good this year, with good yields. White mold started to show up in the later part of the season.


Crookston
Planting Date: May 15
Previous Crop: Wheat
Seeding Rate: 12 viable seeds/ft2
Seed Treatment: Furadan CR-10, Benlate
Soil Type: Clay loam
Soil Test: 26-22-600 N-P-K
Fertilizer Applied: 100-20-0-15 N-P-K-S in the fall
Yield Goal: 2200 lbs/a
Row Spacing: 6 inch -10 rows
Harvest Date: August 13, 18, 21
General Observations:
The Crookston site looked good this year despite the flooded conditions it received in early spring and early July. The low yields experienced at Crookston are probably a result of the spring flooding which likely caused us to lose some nitrogen. The high C.V. of the yield is likely due to the flooding that occurred in July. During the July flood, half of each rep in the trial was under water for about two days with some plots in small depressions sitting under water much longer. There were major yield reductions in plots that were in the depressions. These plots had their yields adjusted to better reflect variety performance.


Kennedy
Planting Date: May 31
Previous Crop: Wheat
Seeding Rate: 12 viable seeds/ft2
Seed Treatment: Furadan CR-10, Benlate
Soil Type: Clay loam
Soil Test: 34-10-400-8 N-P-K-S
Fertilizer Applied: 5-35-0-6 N-P-K-S; 110 lbs as urea in the fall
Yield Goal: 2100 lbs/a
Row Spacing: 6 inch -10 rows
Harvest Date: September 8, 23, October 2
General Observations:
The Kennedy site turned out better than we expected. Unfortunately, we were forced to plant this site into dry soil and the area did not receive rain for three weeks. At least a few seeds in each plot germinated early, but most didn't germinate till it rained. In mid-July the two flushes were very obvious. The early flush was in full bloom while the late flush was just bolting. The 10% and 90% bloom notes were not taken due to the two flushes. Fortunately, the cool August allowed the late flush to set good seed. The field, which the Kennedy site was located in, consisted of Hyola 330 and Hyola 420. It also had two flushes and yielded about 1760 lbs/a.
The Kennedy site was not end trimmed, like the rest of our sites, so yield was estimated on a basis of 6' x 22' to account for the border effect on the ends of the plots. Normally, plot sizes are 5' x 20' on 6' centers and are end trimmed to 15' long shortly before swathing providing a harvested plot size of 6' x 15'. The lack of end trimming may have given the hybrid canola's an unfair yield advantage over the open pollinated lines. Plots were swathed as the majority of each plot reached physiological maturity.


Fosston
Planting Date: May 21
Previous Crop: Wheat
Seeding Rate: 12 viable seeds/ft2
Seed Treatment: Furadan CR-10, Benlate
Soil Type: Clay loam
Soil Test: 58-34-320-23 N-P-K-S
Fertilizer Applied: 13-30-0-15 N-P-K-S; 70 lbs as anhydrous in spring
Yield Goal: 2100 lbs/a
Row Spacing: 6 inch -10 rows
Harvest Date: August 26, September 9
General Observations:
The Fosston site looked very promising this year with good yields, good uniformity and only a little white mold. Unfortunately, soon after the late plots were swathed, a storm came through with very little rain and 70 mile per hour winds that lasted about four hours. The wind caused losses to most of the plots that were still in the field. Overall, 38% of the plots were damaged by the wind, which affected the yields of 26 of the 35 varieties. In the data summary, were reported an estimated yield for the varieties that were affected by the winds. The yield adjustments were based on an estimate of how much of each plot blew away. We are making adjustments on our plot layout for next year to avoid a similar problem.

Williston
Planting Date: May 5
Previous Crop: Fallow
Seeding Rate: 8 lbs/a PLS - B.napus and 6 lbs/a PLS - B.rapa
Seed Treatment: As treated by supplier

Row Spacing: 6 inches
Harvest Date: B.napus August 19,23,26, B.rapa August 14, 19
General Observations:
No significant rainfall received in April, May and nearly all of June. This caused early stand establishment problems. Then over five inches of rain was received on June 30, July 1, and July 2, resulting in some late germination plants. Last flowering date was not recorded.

Fertilizer Applied: 100 lbs/a 18-46-0
Yield Goal: 2000 lbs/a
Row Spacing: 7 inches
Harvest Date: August 19
General Observations:
Planting date was 3-4 weeks later than normal. Growing conditions were generally favorable early in the season with mild temperature and adequate moisture. Growing conditions gradually deteriorated as the season progressed with hot daytime temperatures and little rainfall. Insects problems (flea beetles, armyworms, grasshoppers) were insignificant. Diseases were not observed.

Prosper
Planting Date: May 19
Previous Crop: HRSW
Seeding Rate: Varied with species
Seed Treatment: Furadan CR10
Soil Type: Parella-Bearden silty clay loam
Soil Test: 34 lbs/a N, 14 lbs/a P, 500 lb/a K
Fertilizer Applied: 100 lbs/a (82-0-0)
Yield Goal: 2000 lbs/a
Row Spacing: 12 inches
Harvest Date: August 21 and September 25
General Observations:
Alternating wet and dry conditions immediately after planting caused uneven emergence and then uneven maturity in the plots. Sclerotina was prevalent throughout the trial and grasshoppers damaged both the leaves and pods on the plants.


Langdon
Planting Date: May 20
Previous Crop: Fallow
Seeding Rate: 17 PLS/ft2
Seed Treatment: Furadan CR-10, Benlate
Soil Type: Svea loam
Soil Test: 108-30-255
Fertilizer Applied: 120 lbs/a (46-0-0),
Yield Goal: 2400 lbs/a
Row Spacing: 6 inches
Harvest Date: August 22- B.rapa, September 2-15 B.napus
General Observations:
The growing season was quite favorable for canola production. The key was establishing good stands as late May and early June seedbed conditions were very dry. There was a fair amount of lodging in the trial this year. Some lodged plots send out branches from axially buds which resulted in later end flowering than had the plot not lodged.


Pekin
Planting Date: May 27
Previous Crop: Barley
Seeding Rate: 17 PLS/ft2
Seed Treatment: Furadan CR-10, Benlate
Soil Type: Svea loam
Soil Test:
Fertilizer Applied:
Yield Goal: 2300 lbs/a
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.
