Farmers across the Corn Belt produce millions of bushels of the crop from which the region derives its name, thanks in no small part to centuries of evolution in plant breeding, farming practices, and biotechnology. It's that evolution that event organizers want to highlight.
"We're trying to tell the story of technology in corn," says Harold Watters, Ohio State University Extension educator and coordinator of Extension's Agronomic Crops Team. "From teosinte on through to the most modern quad stack, we'll talk about plant breeding and technology development. "Corn is a wonderful example of a modern plant that we've developed from a simple grass into a major crop."
The "antique corn display," as Watters calls it, is a key feature of the Agronomic Crops Team's demonstration plots, located near the main entrance on the east end of the Review's exhibit area.
In addition to displaying several varieties developed over the past two centuries, he said OSU Extension experts will discuss the development of modern farming practices - perhaps equally responsible for rapid acceleration of agronomic productivity.
"We talk about how farming practices have developed," Watters explains. "I've got some demonstrations where I put in different populations - some varieties from a hundred years ago right next to some of the modern varieties - to see the differences."
He said the varieties exhibit obvious and significant differences in traits like standability, stalk quality, root strength, ear size and kernel count. "It's not just biotechnology, but plant breeding improvements as well."
Watters said the demonstration isn't just about the differences in the plant itself, but also about differences in how the plant and kernel are processed and used in the modern production chain.
"It's pretty striking: We have pod corn, gourd corn, flint corn and others," he said. "Modern processing practices play a big role in helping us get higher starch content and energy. We no longer have to grow a single variety for a single application because of the processing we have today. That's where the Cargills and Andersons out there have come right along the breeders and geneticists."
The Agronomic Crops Team demonstration plots also feature issues and management practices in both soybean and corn production, as well as insect management, cover crops and bioenergy crops.
