Seven has always been considered to be the perfect number, so it’s no surprise that there are seven factors that make up the combination for consistent high yielding corn crops.

A new website looks at “The Seven Wonders of the Corn Yield World,” based on the research of University of Illinois plant physiologist Dr. Fred Below.

Dr. Below has been on a quest to help all farmers achieve the Holy Grail of corn – consistent 300 bushel per acre yields – ever since he saw it happen more than 25 years ago. He 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 yield.

“Roughly speaking, the higher up on the Wonder list the more control that 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:

1. Weather
2. Nitrogen/fertility
3. Hybrid selection
4. Previous crop
5. Plant population
6. Tillage
7. Growth regulators

Below will present his plots and detail the 7 Wonders of the Corn Yield World in person at the annual Farm Progress Show at the AGROTAIN exhibit (lot 1164 on Eleventh Street) Aug. 30 – Sept. 1 in Decatur, Ill. Below’s plots at the show were sponsored by AGROTAIN International, BASF, DEKALB and Mosaic.

I interviewed Fred about the 7 wonders earlier this year at the GROWMARK FS Green Plan Solutions “In Pursuit of Maximum Yields” conference. Listen to that interview here: Fred Below Interview
