University of Illinois Online Agronomy Handbook

For more than 25 years, farmers and their advisers have turned to the Illinois Agronomy Handbook for the research-based guidance they need.  The Handbook is now in its 23rd edition. It is edited by Robert Hoeft and Emerson Nafziger of the Department of Crop Sciences, University of Illinois.

Research

The mission of the research program is to answer corn management questions expressed by Wisconsin farmers. Although farmers are the primary clientele, the general public ultimately benefits and pays for this program. Therefore, we consciously evaluate impacts of this program on society and keep the public aware of how we spend their money. Specific objectives of this project focus on management decision-making regarding crop productivity, quality, and production efficiency including hybrid selection, rotation, tillage systems, and replant and yield loss damage assessments. Emphasis is on impacts of cropping practices on grower profitability, the environment, and natural resource conservation.

General Program Areas:

  1. Cultural practices integrated with changing technology (i.e. plant population, planting date, row spacing with hybrids, tillage, pest control, etc.)
  2. Growth and development interactions with management and environment
  3. Reactive observations and issues (primarily environmental stresses, "Opportunistic" research i.e. frost, drought, hail)
