The first week of February had highs in the 50’s and 60’s and we hadn’t had any significant rain for a couple weeks. Wheat and barley comes out of dormancy with sustained temperatures that high. It needs a small amount of fertilizer to feed on and encourage tillering (when the plant makes multiple stalls) which is important for yield and competing with weeds.
