<p>Dave Hula, Charles City, Va., who has won several national corn yield contests, stands in front of his corn plot on Hefty Farm. Yield contest winners compete with Brian and Darren Hefty in a First Steps trial to see who can produce the highest yield. Detailed records are kept of the inputs used, rates applied and how much each person spent on their plot. “It’s not officially a competition,” says an AgPhD spokesperson. “It’s more like, ‘How would this world record yielder manage crops in fields like ours?’”</p>
