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
The discovery of the opaque2 (o2) mutation and o2 modifier genes in maize (Zea mays L.) has resulted in the development of Quality Protein Maize (QPM) lines with increased lysine and tryptophan content. The QPM lines BQPM9 (Reg. No. GP-584, PI 671795), BQPM10 (Reg. No. GP-585, PI 671796), BQPM11 (Reg. No. GP-586, PI 671797), BQPM12 (Reg. No. GP-587, PI 671798), BQPM13 (Reg. No. GP-588, PI 671799), BQPM14 (Reg. No. GP-589, PI 671800), BQPM15 (Reg. No. GP-592, PI 673348), BQPM16 (Reg. No. GP-590, PI 671801), and BQPM17 (Reg. No. GP-591, PI 671802) were developed jointly by Iowa State University and the USDA-ARS to address the lack of QPM lines adapted to the US Corn Belt. These lines originated from crosses made between two QPM lines from the International Maize and Wheat Improvement Center (CIMMYT) (CLQ06901 and CLRQ00502) and six inbred lines released by Iowa State University (B91, B97, B98, B99, B100, and B113). Increased lysine and tryptophan content, characteristics associated with the presence of the o2 mutation, and agronomic performance were used as selection criteria in the development of the nine BQPM lines released herein.
