First hollow stem is the optimal time to remove cattle from wheat pasture (full explanation). To monitor first hollow stem, we measure hollow stem for the 56 lines in our September-sown wheat forage plots at Stillwater each year. Almost all varieties are well past first hollow stem. Full results are posted in the table below. Varieties with no value for first hollow stem reached first hollow stem on a previous measurement date.

This will be the last first hollow stem update of the 2015 season. You can check progression of first hollow stem around the state by using the First Hollow Stem Advisor on the Oklahoma Mesonet site
