CORN
  • Plant 30 lbs of seed
  • Yield 10,000 lbs of grain
  • > 300 x increase

Chad Lee, University of Kentucky, 2006

corn hybrid performance trials
Corn Hybrid Performance Trials
  • Over 140 hybrids
  • Separated into maturities

corn yields and ethanol production
Corn Yields and Ethanol Production
  • 20 hybrids
  • Grain yields checked at 4 locations
  • Controlled pollination at one location
  • EtOH checked at an independent lab

corn planting
Corn Planting
  • Planting Date
    • April 1 to May 1
      • western Kentucky
    • April 15 to May 15
      • eastern and central KY
    • Soil temperatures should be above 50oF at a 2-inch depth for 3 or 4 days
  • Planting Depth
    • 1 ½ - 2 inches

soybean rust 2007
Soybean Rust, 2007
  • 2006: more ASR found in deep south than in 2005
  • ASR found in about 17 KY counties in 2006 (1 county in 2005)
  • Drought in deep south in 2006
  • When water came, so did the ASR

Chad Lee, University of Kentucky, 2006

soybean rust 200736
Soybean Rust, 2007
  • Dry summer, no ASR
  • Normal/wet summer, need to watch for it

Chad Lee, University of Kentucky, 2006

soybean fungicides
Soybean Fungicides
  • For ASR, must have a triazole in the mix
    • Examples: Folicur, DoMark
  • “Plant Health”
    • Economic yield response 29% of the time

production practices what we know so far
Production Practices(What we know so far.)
  • 40-acre field (overall field average reported at over 110 bu/acres)
  • Poultry litter (high nutrient levels)
  • Intensive tillage
  • Corn the previous year

  • Glyphosate applied for weed control
  • Headline + Warrior applied twice

Chad Lee, University of Kentucky, 2006

production practices what we know so far47
Production Practices(What we know so far.)
  • Irrigation: applied every day or every other day from July through maturity
    • Applied at 0.1 to 0.2 inches every day
    • OR, 0.2 to 0.4 inches every other day
    • Goal was to keep the soybean cool
  • N applied through the irrigation system
    • Ammonium sulfate?
