There are several factors that go into raising high-yielding corn. Fred Below, a plant physiologist at the University of Illinois, cites seven wonders of the corn yield world. Topping the list are weather and nitrogen, each worth 70 bushels per acre apiece. The hybrid itself is worth another 50. All told, they amount to 260 bushel per acre corn.
Below isn’t satisfied, however. Speaking on behalf of nutrient specialists Koch Agronomic Services at the Farm Progress Show, he preaches a possible 300 bushels to the acre if everything is right.
