Right now the corn doesn't hold much attraction for the deer, they won't feed on the plant unless under duress. Once the ears come to maturity the deer will start hitting it. You will find they like to bed inside the field and just eat where they are. If water is scarce I'd set up between the corn and a water source. Also they will most likely still abandon the corn for acorns once they start falling. Corn is astarch and they need the protein the acorns offer to beef up for the rut. Standing corn later can provide good stalking opportunities if the plants are planted wide enough for you to get through. "BowHunting October Whitetails"has a good segment on techniques for hunting standing corn. Hopefully after the corn harvest the farmer will plant winter wheat between the rows which will make for some great late season hunting.
