We plant Food Plots here in Missouri since we aren't allowed to put out any "Bait" for Deer or Turkeys.We can fed them in the Off-Season but all food (Grain) has to be removed 10 days before any Hunting Season.
I usually put corn in a Plastic PVC pipe that's screwed to a Tree and set up a Trail Camera to get pics of what Deer are around.

In Camo Chic's question and Texas8Point about putting Oats out is the Deer Love them especially the Young Fawns that like something tender to eat.I get a lots of Quick Oats that are outdated or damage/spilled at work and I put them out in the Off-Season Season for the Deer and they really like them and the Racoon's do too.

We can put out Salt and Mineral Licks too and those do really good to draw in the Deer.I usually dig up a small area and put in a 1/2 box of Arm & Hammer Super Washing Soda then pour out 15-20 lbs of Salt then the other 1/2 of the A & H and let the rain work it into the ground.I have also put out a 50 lb salt block or used some Lucky Buck mineral to help in the Bucks Antler growth.

You can also do what was mentioned earlier and pour the Salt or Minerals on an old tree stump or log and the Deer will tear it up there too.
