Jeff Edwards and J.D. Carlson of Oklahoma State University Extension talk about wheat, identifying first hollow stem, and the Mesonet’s First Hollow Stem Advisor tool.

No-tillers will need to wait until temperatures warm up to determine whether freeze damage has occurred to the wheat crop, says the University of Kentucky.

To determine how much nitrogen to apply this spring, North Carolina State University Cooperative Extension says to submit tissue samples when wheat reaches GS-30.

Wheat that has been grazed too severely is more susceptible to sudden and sharp drops in temperature experienced at times this fall and winter, says Kansas State University Extension.

Very warm temperatures can cause wheat to break dormancy this time of year, says Kansas State University Extension. When daytime highs get into the 50s F and lows are above freezing, most wheat varieties will lose some of their winter hardiness.

There are several herbicide options for controlling winter annual broadleaf weeds in wheat. Generally, fall applications provide the best control of winter annual weeds with any herbicide, as long as the weeds have emerged, says Kansas State University Extension.

A new report from researchers at the University of Minnesota has found that climate variability historically accounts for one-third of yield variability for corn, rice, wheat and soybeans worldwide.

Researchers found wheat that's resistant to Fusarium Head Blight has specialized and protective cell walls, which may help produce disease-resistant varieties of durum wheat.

Brian Arnall, soil nutrient specialist at Oklahoma State University Extension, talks about soil nutrients and nitrogen-rich strips, which should appear soon in wheat fields.

Although a cold front has made it easier to get across wet fields, the University of Tennessee says it's still early for the first nitrogen application in a late winter/early spring split-nitrogen application approach.
