Driftless SW Wisconsin | Strip till is an alternative for corn on corn in some areas - not all.
We have several customers I can think of who are mostly corn or 100% corn and if there is a yield drag it is not obvious.
Again, please think in terms of net profit not just yield! Max profit does not necessarily occur at max yield. In fact max profit may rarely occur at max yield. jmho & experience.
Here is a photo of a poster put together by one of our customers for a strip till field day last week. These are his numbers, not mine. Used by permission.

PS should explain the second poster on fert rate reduction with strip till. This SE MN customer applies a portion of his corn N and all P & K as dry with our strip till system in the spring. The corn then gets the balance of its N as liquid 28% sprayed behind the row on the planter mixed with Roundup and a residual herbicide. The comparison is to his previous method of broadcast, if I understood hiim correctly. In any case, his corn looked very good.
