Manitoba | Pioneers research will tell you that row spacing is very variable depending on how far north or south you are. The further south the wider row spacings tend to do well, only giving up a small yield penalty to 30" rows. As you move north the wider rows really start to lose yield. Twenty and twenty two inch rows really only seem to have a yield advantage in the northern corn belt and it's pretty insignificant when you consider the extra costs of running on the narrower rows. Their research also shows that twin row corn has absolutly no yield advantage at any given population proving that spacing out the plants and upping the population just doesn't work. It's got to be good info when a company who sells seed is saying that high pops and better spacing doesn't pay when it would be advantageous for them if it did. Almost all of the research was done in conjuction with Colleges all across the corn belt. | |
