It all depends on what you plant and what food is readily availible in the immediate area. This year I have beans on my property, as well as red & ladino clover food plots. The deer will and are eating the beans right now. They haven't even touched the clover yet. As soon as the soybeans mature, they are not as palatible and the deer will move to my clover field.
Corn doesn't contain the nutrients that clover, beans, brassicas, or any other food plots. It is simply a great energy provider and fat builder.
Dont be afraid to plant (anything). The deer will eat it and learn to prefer it over the corn.
You might think about doing a late season forage if you have both corn and beans in the area. That way you will provide food in the later part of fall as well as the winter.
Good Luck,
BT
