High-Yield Soybean Production Demos

 

High-Yield Soybean Production Demonstrations

Objective

  • Impose multiple high-yield soybean production strategies at several on-farm locations to evaluate the effectiveness of these combined strategies for increasing soybean yield.

Study Description

  • 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:
          Early planting
          Optimal seeding rate (150,000 seed/acre)
          Raised beds
          Frequent irrigation
          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)
          94Y81 (RR)     MG 4.8 (2011 and 2012)
          95Y10 (RR)     MG 5.1 (2011 and 2012)
  • University of Arkansas Collaborators:
          Dr. Larry Purcell - Plant Physiologist
          Ryan Van Roekel - Graduate Research Assistant

Location Challenges

  • 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.

Glyphosate Tolerant    R - Contains the Glyphosate Tolerant trait. Always follow grain marketing, stewardship practices and pesticide label directions. Varieties with the Glyphosate Tolerant trait (including those designated by the letter “R” in the product number) contain genes that confer tolerance to glyphosate herbicides. Glyphosate herbicides will kill crops that are not tolerant to glyphosate.
