Organizational Unit
Agronomy

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.

Dates of Existence
1902–present

Historical Names

  • Department of Farm Crops and Soils (1917–1935)

Abstract

We analyzed five near-isogenic brown-midrib hybrids in maize via pyrolysis/gas chromatography-mass spectrometry (Py/GC-MS) in order to determine how differing lignin composition and structure impacts individual bio-oil compounds. Twenty six compounds were analyzed for differences among the five hybrids and between cob and stover materials. We found statistically significant differences for 9 compounds, when comparing the five hybrids, and 17 significant differences when comparing maize cobs with stover. Our data indicate that it may be possible to predict phenolic compounds within bio-oil based on cell wall lignin composition. The genetic variation observed in this study suggests that bio-oil quality can be improved by plant breeding.
