Farm Journal Field Agronomist Ken Ferrie classifies corn hybrids according to leaf structure and ear type. While yield remains the No. 1 factor when selecting hybrids, it’s important to recognize and use the leaf and ear traits to manage soil water more efficiently in each field and each soil type/management zone.
To maximize light interception and water use, it’s crucial to understand the three components of yield: sunlight, water and nutrients. Drawing on the traits of the four leaf structures and four ear types, Farm Journal Field Agronomist Ken Ferrie offers the following recommendations for various environments.
