SOYBEANS

Soybean Sites

=2016 =2015 *2019 sites not yet included on map =2017 =2018

Protocol – Soybean Seeding Trial

• Over 40 sites across the Maritimes (over 5 years)
• Second year with low seeding rates per acre:
• Seeding rates: 90,000; 110,000; 130,000; grower rate
• Prior (2015-2017) seeding rates: 130,000; 160,000; 190,000
• Minimum 1 acre plots and minimum, harvested area was 0.25 acres.

Protocol – Soybean Seeding Trial

• Initial results (statistical analysis not yet completed)
• Following results based on seeding rate, not emergence
• After lunch - trends within the data to draw more information
• Emergence
• Previous crop
• Equipment

Sulfur and Boron

Sulfur is important for:

• Protein formation
• Nodulation
• Proper maturity
• Seed and oil yields
• Nitrogen metabolism
• Soil microbial activity
• Helps release B & Mg from soil for plant

uptake

Boron is important for:

• Plant hormones
• Nitrogen fixation in nodules
• Pollen viability and flower and pod

development

• Structural integrity of plant membranes

– growing points

Protocol – Soybean Nitrogen/Sulfur Trial

• Second year of the experiment with 16 sites across the Maritimes
• Treatments: No sulfur or nitrogen, 30lbs/acre sulfur + no nitrogen,

30lbs/acre sulfur + 30lbs/acre nitrogen, 30lbs/acre sulfur + 60lbs/acre nitrogen

• All sulfur applied in sulfate form
• Initial Results, no statistical analysis completed yet
• Minimum 1 acre plots with 0.25 acres harvested

Protocol – Soybean Boron Tri rial

• First year of the trial
• 14 sites across the Maritimes
• Treatments: no boron, 1 lb/ac of solubor
• Initial Results, no statistical analysis completed yet
• Minimum 1 acre plots with 0.25 acres harvested

PEAS

Protocol – Peas Gypsum Sulfur Trial

• Trial had 2 sites in PEI and 2 sites in NB
• Researching the use of gypsum as a source of sulfur
• Treatments: no sulfur; 0.5 tonnes/acre of Gypsum/23% Ca/18% S
• Initial results (statistical analysis not yet completed)
• Minimum 1 acre plots with 0.25 acres harvested

Peas Gypsum Trial 2019 Yield Results

Protocol – Peas Seeding Rate Trial

• First year of trial with 1 location in PEI and 2 location in NB
• Treatments: 75 seeds/m2, 90-100 seeds/m2, 125 seeds/m2
• First year of data collection, no statistical analysis
• Minimum 1 acre plots with 0.25 acres harvested

OATS

Protocol – Oats Nitrogen Fungicide Trial

• 2 sites in NB with 2 varieties (Nicholas and Camden)
• Purpose is to measure effects on yield of nitrogen amount, fungicide

and growth regulator.

• Nitrogen treatments – 45 lbs/ac nitrogen, 45lbs + 20 lbs topdress

and 45lbs + 40 lbs topdress.

• Growth regulator – 45lbs/ac + 40lbs topdress
• Fungicide treatments vs. no fungicide
• Minimum 1 acre plots

Corn

Protocol – Corn Boron and Sulfur Trial 2018-19 19

• Experiment conducted on corn snaplage (NB) and grain corn (NS & PEI)
• Purpose is to measure the effects of boron on corn yields, alone and in

combination with sulfur.

• Three treatments
• Control – no boron or sulfur
• Add Boron – 1 lb/ac borate in topdress
• Add Boron and Sulfur – 1 lb/ac borate and 25 lb/ac sulfate in topdress
• Minimum 1 acre plots, no statistics complete yet.

Winter Wheat

Protocol – Winter Wheat Early/Late Seeding 2019

• First year of experiment with harvest in 2020.
• Build on the 2016-18 PEI trials which used planting dates of Sept 15-30 and

Oct 1-15.

• Early and late seeding dates were determined for areas across the

Maritimes based on growing degree days.

• Goal was 450 gdd for early planting (Sept 20-30) and 250 gdd for late

planting (Oct 15-30).

• Three treatments
• Early planting 1.7 million seeds per acre

Protocol – Winter Wheat Early/Late Seeding 2019

• Goal was 450 gdd for early planting (Sept 20-30) and 250 gdd for late

planting (Oct 15-30).

• Three treatments
• Early planting 1.7 million seeds per acre
• Late planting 1.7 million seeds per acre
• Late planting 2.1 million seeds per acre
• Minimum 1 acre plots with 0.25 acres harvested
