You need some of the 8 to 5 seeds. They open up during the day to allow the deer to eat on them but then retract back in the ground at night.
You really need to take some soil samples to see what your soil will grow and lots of other factors like sun vs. shade, growing zone, etc. There are some good articles on growing food plots on the
www.qdma.com site.

Also as mentioned earlier there is a separate wildlife managment forum here that has some good information as well.
