I'm in SE Ohio and plant food plots as much for the fun of it as I do for the benefit of it. My plots barely matter to our deer given the available ag and browse within our general area. But I love the process and the expense is nominal compared to my other hobbies, so it's well worth the return I get from the whole ordeal. I plant via all methods from frost seeding, to no-till/poor man's style, to walk-behind tiller, to 55hp tractor with 60" box tiller. It just depends on the size and location of the plot.
I frost seeded Whitetail Institute Imperial Clover in late-February on an established clover plot that's near the end of it's life. I'll spray for grasses and broadleaf in the next 2-4 weeks and if it doesn't come around, it'll get tilled under and reestablished in mid-May.
I'll be planting corn in our big creek bottom plot using a walk-behind single row planter. Going for 18 rows, 100 yards long for the first time ever. It's a former turnip, then clover plot, that didn't get mowed last year. I may mow it short and plant corn no-till style and see how it goes. Still undecided in that regard.
I have two more creek bottom plots that get annuals and I use a walk-behind tiller. I planted Frigid Forage Autumn Quick Plot last year with great results, but I may shift to a mix heavier on the cereal grains. I have time to decide, but it'll definitely lean towards the oats/rye end of things than brassica/turnip end of annual mixes.
I have some switchgrass to plant too. Although not a food plot, same process. I'll do that in May.
