St. Claude, Mb, Canada | I feel like that was a bad appraisal or there is more to the story, like planting at 50k or something. In our northern environment, 20" gives up yield unless population is pushed with a determinate ear type variety. At that point the extra seed cost and the fact that your row equipment is 50 percent more expensive any yield is completely given back in extra costs. Plus 20" is a pain to work on. The other bonus of 30" is it allows us to push for corn that is up to 3 days longer, due to the artificial heat units gained with less ground shadow on those June days that aren't getting anywhere close to 90 degrees. | |
