Wheat Specialist Dr. Jeff Edwards Believes Oklahoma Wheat Has Sustained Significant Freeze InjuryTue, 15 Apr 2014 21:31:33 CDT
After many wheat fields across Oklahoma sat nine to ten hours below freezing, Dr. Jeff Edwards, Small Grains Extension Specialist at Oklahoma State University, sounded pessimistic about the 2014 hard red winter wheat crop in the state. Here are some of this comments posted on Tuesday afternoon:
"Most of Oklahoma spent at least four hours below freezing last night and some areas spent an extended period of time below 28F. While temperatures in the wheat canopy might have remained slightly higher than reported air temperatures, they were still probably low enough to result in significant injury to wheat.
"Over the next few days growers will need to inspect fields closely to determine the extent of injury. Symptoms may start to appear later this week and will likely be clearly identifiable by early next week. Healthy wheat heads will remain turgid with a green color. Damaged wheat heads will be bleached, yellow, or brown and will easily break when pushed against. I anticipate that we will not have any partial “blanking” of wheat heads and that most wheat heads will either be okay or a complete loss.
"What about new tillers? New tillers might emerge, but it is already April 15. In addition we have very dry soil conditions. For these reasons I am doubtful that newly emerging tillers will have much yield potential in areas south of I-40. IF (and that is a big if) weather conditions remain favorable, late emerging tillers in northern Oklahoma might still have a shot at producing grain.
"I will survey some fields in a few days and report back with my findings."
Midday Tuesday, Dr. Edwards talked about his fears and concerns for the 2014 Oklahoma Wheat Crop with the SUNUP TV Crew from the OSU Division of Agriculture. You can hear his thoughts by clicking on the LISTEN BAR below.
