Because your region and area may be different than mine in IN I will suggest you reach out to members here from PA or other nearby states. This forum as well as one called deerhunterforum will be a great resource for you to ask these questions and get a far greater array of options than just my opinion. Secondly other professional folks like Steve Bartylla and Jeff Sturgis and their web sites and books. Other threads published by a man named Paul Knox/Lick Creek/ LC/Doubletree - he has passed, but his work and his spirit live on in the foodplot world.
I would also suggest you do some reading....."Quality Food Plots" (used to be available from "the shed" on the QDMA forum), and Jeff Sturgis "by design" book series "food plot success by design", "whitetail success by design" & "Mature buck success by design". Another good book is from Steve Bartylla "white-tailed deer management and habitat improvement". These books have been the backbone of my "deer library" and the forums I mentioned are wonderful additional resources.
I can't possibly tell you what combinations you need or work for each and every "what if"......
To answer one question....MG is a plant called Misganthus Giganticus (look at Bills thread on it). It is a tall perennial grass that is great for screening.
You refer to "stonerows" - I am not familiar with that term. I assume we are talking about the same thing.....this is what I am talking about. Double rows are green, single row is orange. My intent would be to screen your movements.
Even if you turn the entire 4 acres to food plot - I would still break it up with screens (at least at deer level)
Something I like to do is promote mixes of plants. For perennial plots I like mixing different clovers, chicory and maybe even alfalfa. These will come back every year and tend to provide food for your deer primarily in the cool seasons of spring and fall. Most warm season deer foods are cowpeas or soybeans. These are annuals and will need to be planted every year. Other annual plots can be planted in the late summer or early fall to provide food from fall and into winter. These tend to be brassica (turnips or radish), cereal grains (oats wheat and rye) and maybe even some winter peas.
What I suggested with the standing corn or beans is simply using the increased sunlight that becomes available as that crop dries down and the bare ground underneath to your advantage. Brassica plants, cereal grains and even clovers are wonderful for this purpose and provides even more food to be produce "per acre" This process is documented in many places and some have their own "go to" mixes and combinations and "tricks".
I hope this helps some and gives you some direction in where to look for information. How you hunt, when you hunt and your goals all come into play. Year round nutrition is a noble goal.....depending on your deer density and what you can and can't do I am not sue 4 acres can do that. I have 150 acres total and only plot about 3 acres total - as such I target when I am hunting.....if the deer want to eat at the neighbors come spring and summer....I'm OK with that. I have roughly 100 acres of corn and bean field as well......I am also surrounded by 100's more. I also have a fairly low deer population, yet I still try to get as much as I can out of my plots by planting mixes and "layering".
Something I will warn about is over hunting food plots. They are great places to see deer, but without proper planning it is also a great way to educate deer. I am VERY guilty of that. I my short time doing this the ONLY time I have EVER killed a buck of 3.5 or older influenced by a foodplot was because he was after the does feeding there. Some may have different experiences than that, but this has been my experience.
