First hollow stem is the optimal time to remove cattle from wheat pasture (full explanation). This will be the last of the 2016 first hollow stem updates, as the vast majority of varieties are at or well past first hollow stem.
Keep in mind that the numbers reported from Stillwater are likely behind those being observed in southern Oklahoma and ahead of those observed in northern Oklahoma. The First Hollow Stem Advisor can provide an estimate of first hollow stem progress in your neck of the woods.
