Information Management to Maximize Your Yields

Volunteer Corn

As most have noticed, corn fields have a high amount of volunteer corn.

The question is how much it affects yields.

Volunteer corn becomes competitive with the planted corn and acts like a weed.  Research found in South Dakota says volunteer corn can vary from 800 to 14,000 plants per acre.  This causes a yield loss of anywhere of 0 to 13 percent.

Research done by Iowa State found that 1,700 plants per acre will reduce yields by 1.3 percent.  Yield loss increases as dry conditions continue.
