The Department of Agronomy seeks to teach the study of the farm-field, its crops, and its science and management. It originally consisted of three sub-departments to do this: Soils, Farm-Crops, and Agricultural Engineering (which became its own department in 1907). Today, the department teaches crop sciences and breeding, soil sciences, meteorology, agroecology, and biotechnology.
History
The Department of Agronomy was formed in 1902. From 1917 to 1935 it was known as the Department of Farm Crops and Soils.

Abstract
Brown midrib (bm) mutations are known to affect cell-wall digestibility by altering the quantity and composition of lignins in cell walls, resulting in higher ethanol yield and increased cell-wall digestibility. So far, four bm genes (bm1, bm2, bm3 and bm4) were identified and mapped in maize, the last one (bm4) in 1947. In this study, 13 spontaneous mutations (bm*A–M) resulting in the appearance of brown midribs were crossed with bm1–4 for tests of allelism. From these tests, we report two new bm mutants bm5 (bm*F) and bm6 (bm*J) while other bm* lines were either found allelic to bm1–4 or to one of the bm* lines.
