High Plains, South Plains and Rolling Plains suffer damage
AMARILLO – Wheat Freeze Assessment Sessions will be held April 17-18 across the High Plains, South Plains and Rolling Plains after temperatures dipped into the teens and low 20s on April 9-10, threatening much of Texas’ wheat crop.
Dr. Calvin Trostle, Texas A&M AgriLife Extension Service agronomist in Lubbock, and Dr. Clark Neely, AgriLife Extension state small grains and oilseeds specialist in College Station, will attend the meetings to help evaluate samples participants bring and train them to spot freeze damage.
“We have indeed unquestionable and major potential injury on our wheat crop for grain,” Trostle said. “The absolute temperature is one factor and the duration of these temperatures is another. When combined, these two issues significantly raise the injury potential.”
He said temperatures in the northwest and northern South Plains hovered around 20-22 degrees; the Amarillo region, 20 degrees; the southeast Panhandle, 22-25 degrees; and north of the Canadian River, about 15-20 degrees. Some areas were below 28 degrees for about 24 hours.
“There has been enough jointing now into the Panhandle that the growing point most likely experienced the cold temperatures that cause damage,” Trostle said. “Also, the strong wind speed overnight April 9-10 probably circulated the temperatures farther into the canopy, whereas on still nights with only a light breeze, this probably doesn’t happen as readily.
“Likewise, on a windy night, the low end of the field, if there is one, for example, a playa bottom or a draw, might be less likely to demonstrate injury relative to the rest of the field.”
Producers planning to attend one of the meetings should bring 10-20 samples from each field, including roots; a pocket knife or razor blade to cut samples; and field data, such as variety and planting date.
