Curved Ears Indicate Insufficient Nitrogen
Sep 02, 2010
Question: Why am I seeing curved corn ears in my field this summer?
Answer: Curved ears, also called banana ears, are an indication of poor pollination due to a nitrogen deficiency. If the problem resulted from insufficient nitrogen, you usually find that curved ears also have a barren area or strip on one of their sides where no kernels are present. This problem is fairly common this season throughout the Midwest because of heavy rains early on which resulted in nitrogen leaching from the soil profile.
