"WINTER WHEAT - MISSOURI CROP PERFORMANCE FOR 2007, 2006, 2005."
|
|
by Anne L. McKendry, David N. Tague, and Julie K. Solomon.
|
|
|
|
The Missouri trials were at seven locations in 2005, 2006, and 2007.
|
|
|
|
Test weights were the average of the seven locations in 2007.
|
|
|
|
|
Heading dates were recorded when 50% of the heads in a plot had extended above the flag leaf collar.
|
|
Heading dates were significantly impacted by freeze damage, specifically early lines.
|
|
Freeze damage was assessed 10 days after and rated on 0-9 scale with 0 = no visible damage and 9 = 100% of
|
|
plants showing leaf burn and complete stem collapse laading to lodging with plants flat on ground.
