Seven Wonders of the Corn Yield World
•Ranks those factors that each year can have a positive (and sometimes negative) impact on corn yield
•Gives each factor an average bushel per acre value
![Page 3: Fred Below, Jason Haegele, Ross Bender, and Adam … - 7 Wonders of Corn... · Ryan Becker • Ross Bender • Fernando Cantao • Keila Cunha • Paulo Galvao • Laura Gentry •](https://reader031.vdocuments.site/reader031/viewer/2022020315/5ad843d47f8b9af9068d4bea/html5/thumbnails/3.jpg)
Crucial Prerequisites, but not Yield Wonders
•Drainage
•Pest/Weed Control
•Proper soil pH & adequate levels of P and K based on soil tests

How to Get High Corn Yields?
• Optimize each of the seven wonders and their positive interactions
• Provide better prerequisites, season long weed control & balanced fertility/nutrition
![Page 13: Fred Below, Jason Haegele, Ross Bender, and Adam … - 7 Wonders of Corn... · Ryan Becker • Ross Bender • Fernando Cantao • Keila Cunha • Paulo Galvao • Laura Gentry •](https://reader031.vdocuments.site/reader031/viewer/2022020315/5ad843d47f8b9af9068d4bea/html5/thumbnails/13.jpg)
Prerequisites for High Yields?
• Proper soil pH & adequate levels of P and K based on soil tests
• Fertility- Use application and fertilizer technologies to supply required crop nutrition

Conclusions • Yield gains are possible from a
systems approach to crop management that combines individual practices known to impact yield
• Increasing plant population may be the foundation for pushing higher yields, but it must be managed and protected
