southern MN | There is an art to fitting the seed size to the plate.
These days many companies don't do a great job sorting seed by size, since most planters use fingers or air pressure to singulate kernels.
So even if you work at it, might not be able to do real well.
Wrinkled sweet corn seed is even harder to fit in the plate.
Generally you can sort out the width of the notch in the plate to the width of the kernel you have. If kernels are too fat they don't fit in the notch and you will skip a lot.
The trouble is the oblong length, if you pick a plate too short the seed doesn't fit in and it skips, and if you pick too long with poorly graded corn then two small ones try to fit in and double plant.
With sweet corn depth might be an issue too, if it plants doubles might need a different backing plate.
