Coldwater, Michigan | Nothing new about it, just that it is time for it to be going around again. Back in mid 70's Kinze was promoting the heck out of it. Had a couple of customers in Southern Ohio who cut their planter units apart and re-welded them as double row units. We have learned how to possibly make them better. The split row is possibly better than the way they were done last time. We fertilize for them a little different than we did the first time. As a result, several people are having good luck with them this time. Maybe we will come closer to getting it correct this time.
It's a bit like 15" row corn. There are several people planting 15" row corn on this board. In Michigan when the university was running around with their multi row planter, the change from 30's to 15's gave a yield response. Not much, but some when a higher population was added. A few years later when we put fertilizer on that planter in a certain way, the 5-7 BPA gains without fertilizer became 24.4 BPA with fertilizer over a 3 year period.
Sometimes when it comes time for ideas to cycle, the thoughts on how to make things work are different, so the result can possibly be different as well.
Nothing new about the concept of Twin Rows, just the way we do them now.
