August 20, 2007 (updated August 23, 2007)
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.
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.
