Corn Seed Germination - Time Lapse Video

This excellent short video outlines the germination of maize seeds, root shoot formation and crop establishment. A very useful resource for teaching plant reproduction.

Seed corn producers evaluating corn (circa 1950)

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:

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)
