First hollow stem update 03/13/13

Most wheat varieties are now at first hollow stem. As mentioned in previous posts, the drought has wheat development in Oklahoma a good one to two weeks behind normal. If you still have cattle on wheat pasture it is past time to remove them, as there will be a significant grain yield penalty for further grazing.
