Corn hybrid trials
Corn Hybrid Trials

  • About 140 hybrids

  • 7 locations

  • Compare hybrid relative yield performance

  • Reduce as many other variables as possible.

  • Identify hybrids for your conditions.





LSD = 7.4 bu/acre

Early Average Yield = 170.6 bu/acre

13 Hybrids within 7.4 bu/acre of top yield

57 hybrids total in the Early Test.

2007 Kentucky Corn Hybrid Performance Test, p. 7


LSD = 8.0 bu/acre

Medium Average Yield = 177.3 bu/acre

13 Hybrids within 8.0 bu/acre

76 hybrids total in Medium Test

2007 Kentucky Corn Hybrid Performance Test, p. 8


12 hybrids in White Test

  • Are you getting the most yield for your soybean dollar?


Based on Yields from 2006 Trials and expected performance in 2007.

(The 2006 Soybean Performance Trial was predicting yields for 2007)



2007 soybean performance trials
2007 Soybean Performance Trials 2007.

  • About 200 commercial varieties tested

  • 5 locations (2 were dropped due to drought)

  • The first step in biofuels

  • Improvements in efficiency needed

  • Rotational implications


Why corn
Why Corn? 2007.

  • We can grow it.

  • We can ship it.

  • We can make ethanol from it.

  • U.S. Stats, 2007

  • 84 million acres

  • 154.7 bushels/acre

  • 13.3 billion bushels

  • 495 billion lbs of starch

Corn on corn
Corn on Corn 2007.

  • Pulling acres away from other crops to grow more corn, means more corn will follow corn…



Corn on corn1
Corn on Corn 2007.

  • Yield Penalty ~ 10%

  • Diseases

  • Insects (Corn borer; Corn Rootworm)

  • Fertilizer (N, P, K)

  • Logistics


Starch based ethanol
Starch-based Ethanol 2007.

  • Improvements in efficiency

    • A better understanding of hybrid effect on EtOH is needed

    • Improved Grain Yield

  • Corn on Corn

    • Yield penalty

    • logistics


Expected biofuel yields
Expected Biofuel Yields 2007.

** Not sustainable. Need ~4 ton crop residue (root + shoot) annually to maintain current SOM levels. Soybean residue (root + shoot) = 2 ton/year, so need 4 ton + 2 ton from corn to cover soybean year in 2 yr rotation.

Production practices as we know them
Production Practices 2007.(as we know them)

  • Soybean, Pioneer 94M80

  • Sprinkler-Irrigated every day

  • Fungicide applied (twice?)

  • Foliar feeding?

  • Extremely high populations

  • Walked field every day
