Don't have any experience with lablab, other than a lot of hunters try to plant it in food plots around here, and it seldom works because we do not get enough rainfall. That is why I also have no experience with soybeans.

If you are planting for deer, I would not plant sunflowers. Deer will sometimes eat them, but it is generally not their favorite. Here, they won't eat them until they are very hungry and very desperate.

I would be careful with corn in a mixed planting, because corn can grow very tall very quickly. If it is very thick, it will have a very pronounced shading effect.

Alfalfa or a clover might work. Both will attract deer.
