Explore The Seven Wonders Of Corn

Explore The Seven Wonders Of Corn

New website shows the impact of various practices on corn yield. University of Illinois corn expert Dr. Fred Below will be giving his presentation on this topic in person at 2011 Farm Progress Show at Decatur, Illinois.

Ever since he witnessed 300-bushel-per-acre corn more than 25 years ago, Fred Below, Ph.D., has spent his career researching how other farmers can do it, too. Through the years, the groundbreaking information he's discovered about the specific factors that affect crop yield are now available to the public at www.7WondersOfCorn.com.

Below, a professor of plant physiology in the Department of Crop Sciences at the University of Illinois at Champaign, has categorized the results of his research into seven management practices or "wonders" that can result in high yielding corn. His study helps growers answer the question of what the latest products and practices contribute to corn yield.

Below's unique "omission plots" allow him and his research team to see the bushel impact when an individual "high tech" practice or input is added or subtracted, then compare it to other plots in which all "high tech" actions were in place in the same research plot. Replicated in various locations over various years, the test results have allowed professor Below to identify and rank those seven factors as having the greatest impact on corn yield.

Website explains what the multiple-year, omission-plot research shows

"Roughly speaking, the higher up on the Wonder list, the more control that a particular factor exerts over the Wonders that follow," Below explains. "When combined, all of these factors contribute to big-yield gains." In order of importance, they are:

• Weather

• Nitrogen/fertility

• Hybrid selection

• Previous crop

• Plant population

• Tillage

• Growth regulators

Each one interacts with the others to produce an average bushel-per-acre yield. For example, weather and nitrogen directly affect each other. But Below states that, if used correctly, nitrogen accounts for almost the same value as weather; when combined, weather and nitrogen account for more than half the crop yield. Part of the "high tech" package in Below's study included using urea nitrogen fertilizer stabilized with AGROTAIN technology to control nitrogen losses that typically occur in fields where nitrogen fertilizer is applied.

The new 7WondersOfCorn.com website features separate video segments dedicated to each Wonder, narrated by Below himself. There's also a "News" section about Below's real-world plots at the upcoming Farm Progress Show; and a link to the 7WondersOfCorn Facebook page where growers can share their own photos and experiences. The website is easily navigable.

Below will present his plots and explain in detail the 7 Wonders of the Corn Yield World in person at the annual Farm Progress Show (AGROTAIN lot 1164 on Eleventh Street) Aug. 30 – Sept. 1 in Decatur, Ill. Below's plots at the show are sponsored by AGROTAIN International, BASF, DEKALB and Mosaic. Company representatives will be on hand to answer grower questions as well. The Farm Progress Show is a 3-day show that rotates between Boone, Iowa and Decatur, Illinois. This year it is at Decatur. Next year it returns to Boone.
