Research

Last updated March 18, 2022

Agronomy is the science of land management. Agronomists generate, integrate and apply science-based knowledge and principles to crops grown for food, feed, fiber, and fuel that are efficient, environmentally sound, and sustainable for future generations.

The mission of the Corn Agronomy research program is to answer corn management questions expressed by Wisconsin farmers and industry. 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:

Cultural practices integrated with changing technology (i.e. plant population, planting date, row spacing with hybrids, tillage, pest control, etc.)

Growth and development interactions with management and environment

Reactive observations and issues (primarily environmental stresses, "Opportunistic" research i.e. frost, drought, hail)
