Time to start planting?03/21/2012 - 03/30/2012 Reports show a
farmer in southeast Iowa was planting corn last weekend, and it
turns out he's not the only one rolling in the field. But early
planting doesn't always translate to the best yield. "Planting
in late March or early April has almost never produced higher
yields than planting in late April," says University of Illinois
Extension agronomist Emerson Nafziger. In a dozen trials over
the last 3 years, he adds, the later-planted corn has outyielded
the mid-March plantings 9 times.
