Northern Indiana | We’ve done exactly that with a 1790 planter. One disc pass is awful rough in my book when spring planting rolls around. Have to slow down to maintain consistent depth. We’ve done a bunch of trials on our farm. Fall chisel-spring disk and packer, fall chisel-spring finisher, fall disk-spring disk, fall disk-spring finisher, fall disk-plant, fall disk and packer-plant, no fall work-spring disk and packer, no fall work-spring finisher, no-till. That’s the combinations, and we’ve done some with a roller, some without. Honestly I don’t think any of it makes any difference. Smoothest field all year long was from a fall disk and spring finisher program and it also had the highest emergence rates and the most uniform stand. No-till always looks bad here for the first half of the year. Yield is almost always within a margin of error.
If you truly want to compare costs of programs I think our best comparison would be no-till vs fall disk/spring finisher on 25% less population. My guess is the yield would be consistent so it comes down to seed cost vs fuel and equipment.
Long story short, do what you want ahead of beans, and plant at whatever speed the planter is comfortable at. Most likely it won’t make a difference, in our experience | |
