Dan has some very good points. If winter wheat grows well, so will other cereal grains like oats, rye, barely, or tritacle. Sometimes the deer just need a "different" forage to really make a plot attractive. The last thing I'd plant is wheat, it thats what all the neighbors are doing.
If you soil Ph is good, clover is also an excellent choice. All our land is loamy, and clay. No crop will grow well if the clay prevents water from draining away. If after a heavy rain, you have water that stands for several days, forget about planting there.
The problem with clay is it is hard to adjust the Ph quickly. Often large amounts of lime are required. If, your Ph is good, and you have good drainage, clay can be GREAT. The soil will hold moisture longer, and crops you plant can flourish, even with sporadic rianfall.
Do a soil test, and research other deer attracting plots. A little experimentation can go a long ways as well.
Good luck.
