| We are in NE Nebraska in some rolling hills and experimented with what you are talking about. Tried rye drilled in the fall in twin rows, 30” rows, 15” rows planted parallel to the corn row, and 15” planted at an angle to the corn rows. Lowest yield was the 15” at an angle, then 15” parallel, then 30” and twins. I would say 30” is better than nothing, but when I dug up roots the 30” rye rows roots did not come together in the middle, the twins and 15” did. I don’t think you would have more erosion issues due to a rowed cover crop vs no cover crop. Our current system is planting 15” rye rows and splitting the gap with the corn planter. Best of both worlds in our opinion, and the 10 extra bu per acre compared to bouncing over the rye rows at an angle backs it up. I’d say give it a try as long as you can split the gap planting corn next spring.
