Yes and No. Some manufacturers specifically say do not put whole corn cobs or husks in the disposal, while others do not. While high power models will be able to grind up a corn cob and/or husk, it could take a long time. Also, the strings and fibers in corn husks can sometime get entangled in the disposals gears. So it's a good idea to avoid putting corn husks and cobs in the garbage disposal.
