High-Yield Soybean Production Demonstrations
- Impose multiple high-yield soybean production strategies at several on-farm locations to evaluate the effectiveness of these combined strategies for increasing soybean yield.
Plot Layout: 1 acre on-farm strip plots
Number of Locations:
2 in 2011 (Helena and England, AR)
3 in 2012 (Helena, England and Newport, AR)
High-Yield Strategies Employed:
Optimal seeding rate (150,000 seed/acre)
Twin rows on wide beds
Seed treatments: Optimize® 400, Bio-Forge® ST, FST/IST
High fertility + 2 tons/acre poultry litter
Intensive pest management
Supplemental nitrogen (2012 only)
Pioneer® Brand Soybean Varieties:
94Y40 (RR) MG 4.4 (2011 and 2012)
94Y50 (RR) MG 4.5 (2012)
94Y61 (RR) MG 4.6 (2011)
94Y70 (RR) MG 4.7 (2011 and 2012)

England, AR 2011: Hail, reduced stands, eroded beds, excessive heat and drought. Location almost abandoned.
Helena, AR 2011: Early-season hail, drought and intense heat during pod fill affected later maturing varieties more adversely.
England, AR 2012: Heat, drought and severe stinkbug outbreak during mid to late seed fill.
Helena, AR 2012: Heat, drought and charcoal rot.
Newport, AR 2012: Heat and drought.
