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 • Over 140 hybrids • Separated into maturities • Early (≤112 days) • Medium (113-117 days) • Late (≥118 days) • Specialty groups • High Oil • Ethanol Production Efficiency Chad Lee, University of Kentucky, 2006

TOP YIELDS Chad Lee, University of Kentucky, 2006

Corn Yields and Ethanol Production • 20 hybrids • Grain yields checked at 4 locations • Controlled pollination at one location • EtOH checked at an independent lab Soybean Varieties | Corn Hybrids | EtOH Hybrids | SBR 2007 | Record Yield | Soybean Pops | Corn Silage Chad Lee, University of Kentucky, 2006

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 ID-139: A Comprehensive Guide to Corn Management in Kentucky.

Selecting a Corn Hybrid • High-yielding • University Hybrid Yield Tests • Cornborer-resistant (Bt) Hybrids for late plantings Chad Lee, University of Kentucky, 2006

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, 2007 • Dry summer, no ASR • Normal/wet summer, need to watch for it Chad Lee, University of Kentucky, 2006

The Yield • 139 bu/acre • Kip Cullers, southwest Missouri • Pioneer 94M80 • 2-acre block (1st check) • Separate 2-acre block (2nd check) Chad Lee, University of Kentucky, 2006

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 • No soybeans ever in the field? Chad Lee, University of Kentucky, 2006

Planted May 20, 2006 300,000 seeds/acre 7.5-inch rows Harvested October 7, 2006 245,000 plants/acre 120 pods/plant Production Practices(What we know so far.) Chad Lee, University of Kentucky, 2006

Production Practices(What we know so far.) • Glyphosate applied for weed control • Headline + Warrior applied twice Chad Lee, University of Kentucky, 2006

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?
