Agree, a clover blend may be worth the expense, depending on the size of the area. I read an article done by a biologist where he tested food plots in East Texas, Arrowleaf clover was what he recommended, along with wheat and oats and something else I don't recall, probably clay peas.
If it is a large area, you'd best be served to get a soil sample before spending on seed, prep and fertilizer, soil test run around $20 through A&M.
Another option, have your county Agriculture agent out, they are free and provide loads of information forto you on what plants do well in your county/area.
Before just buying clover seed though, you need to research the various cultivars online, some re-seed well, some don't. They can be picky on when to plant for best growth and some wont hardly grow in certain areas. Your local farm and seed store may also have good info on what other plant around you with success.
If it is a very small area and you have a decent # of deer, you may never get a plot off the ground, even if you do everything right, deer can really mow down something they like.
