I personally have not had any success with anything like that. The thing with small plots is they aren't a magnet. At best they might get a deer that might walk 50 yards around in some brush to stop by the plot. Mostly they might just be a good open place to shoot deer. Light is a big issue. It looks like you have some underbrush, so it might be ok. You could trim a few branches above and get some surprising results.
I have a kinda sorta similar setup except not in the dead center of the woods. It's on the edge of old hard woods, and in an open area where some new hardwoods and thick brush grows. It's a significantly bigger plot than that, maybe 50 yards by 100 yards in size. It's planted with a mix of clover and chicory right now. In that area there's zero reason to plant beans or corn, as the deer only have to walk a few hundred yards in any direction to find thousands of acres of either. Mostly I was hoping this plot would give me better shooting opportunities for the deer that were already there. It hasn't drawn many, I'll have to check my trail camera to see if turkeys used it this spring. It gets a lot of summer and early fall use, but last fall it didn't really produce much. I'm going to try burying one of those plastic waterhole tanks to see if any water might be a draw.
The plot that did produce is an actual food plot. I don't know the exact size, call it 3/4 acre. It's fairly open, but good tall, like 8' or more tall grass on half, and a patch of woods on the other. It's got a decent hill on the other, so all sides is decently secluded. That is really the bare minimum I have found that really has any effect on deer come hunting season. Any smaller than that, and it's eaten within a month. Think like a garden, if deer got into your garden how long would it last? I planted half that big plot with a mix of oats and rye and some other stuff, peas I think. The other half was a brassica mix with turnip and radish and things like that. They didn't care as much about the grass side, but they loved the brassica side. This year I'm probably going to plant the outside edge in that wheat/rye mix, and the center in brassica. It doesn't draw deer from a long ways away, but deer you rarely saw, were suddenly a daily sight. It really did good in October. There was food left in November, but the hunting pressure reduced daylight sightings. If I owned that property, I would make it even bigger, but I don't want to push my welcome. I'm fortunate as it is to be able to do that. All I used for equipment was a backpack sprayer and an old disc maybe 6' wide I found in the junk pile. I sprayed roundup to kill the grass, then a couple weeks later pulled the disc around with the truck to till it up. I then spread seed with one of those cheap hand seeders, and ran the disc over once more to get the seed in the dirt. I messed up my soil sample, so I just threw a bunch of 10-10-10 fertilizer. I think 100 pounds when I planted, then another 100 pounds a month later. It all grew up good if you ask me.
