August 20, 2007 (updated August 23, 2007)
Over the last two
weeks I have received several calls about multiple ears on corn plants and I have visited
some of these fields. Often there are 2
7 ears at one node and sometimes there are multiple ears at several nodes.
This is a phenomenon
called twinning that was observed from Ohio to Iowa in 2006 and is showing up
in these states again in 2007. Several
articles have been written about it.
