We started cutting three weeks to a month ago, and are still cutting depending on variety and location. We have two "regions" in my part of the state, we have what we call the "Bottom", and then the hill ground. The "bottom" is simply the Mississippi River flood plain. Perfectly flat land that extends 15 to 20 miles east of the river banks, and the hill ground which average 150 ft higher than the bottom with a sharp bluff type transition between the two regions. I mention that because when we farmed we worked ground in both areas, and it is completely different land with different schedules between the two mostly due to soil type. We would plant the hill ground usually within the second week in May and could wait as late as June to get the bottoms in. Slightly cooler temps in the bottom, and better soil result in the one to two week delay. While we never did it, One thing others have done , and I saw my neighbor do it last year, and thats plant an early variety of corn, harvest it, and immediately plant beans behind it, and get away with it. That has only been successfully accomplished down here in the bottom in my area. try that in the hills and lose a bunch of money in fuel and seed. I myself am what us locals call a "bottom rat" my house is in the flood plain, I live about 5 miles from the bluff and in 2010 I had 7 1/2 ft of river in the first floor of my house. Its a fertile land, but you have to be accustomed to the river going where it wants when it wants. Just this season alone I watched the river take out thousands of acres of corn crops.
