Scott City KS | My part of the world water is everything. KSU data out of Tribune shows a tillage pass costs between .5-1" of soil moisture. Probably more with a chisel plow. That part is a big deal to us. As well as the residue on top to prevent evaporation.
As far as tillering, tillage removes the residue from the topsoil, raising the temperature, so growth is probably more aggressive with tillering.
You can offset that with higher seeding rates if you in fact want more heads out there.
If you're looking at no-till wheat on wheat, There are several other factors to consider, disease is one. I don't know exactly what you're looking at from a disease perspective, but probably should research.
Also tillage forces advanced breakdown of residue which releases nutrients from the residue (organic matter too, which is not cool). You probably need to up the fertility rates - which you should probably do anyway to not cannibalize your organic matter. It is a misconception that you have to apply more fertilizer under no-till. You just have to move up the timeframe.
I raise better wheat under no-till, but you have to pay more attention.
Hope it helps. | |
