Which corn seed size plants the best?
Provide corn seed size R1, R2, R3 or F1, F2, F3 (R2 = Round @ 45-55#) and the make/model or planter unit technology/era.
Medium rounds plant with almost 100% accuracy in my white 8524.
Plant alot of F1 seed size. Use white 6180 and white 8523.
Case 1250 planter. I like R2 and 45-55#
6100, 8 row White planter. I want larger rounds, 54# & up. I modified the air holes in the plates, used a rotary file in my drill to make the holes bigger, to hold the seed better, so brushes wouldn't brush off any kernels. Like it would do for flats, easy to wipe them off. Found that out the first year we bought the 5100 4 row white planter. We had ordered flats for our old IH 58 planter I think it was. It had the medium plates the planter came with or large, i can't remember, the White. We were getting lots of doubles then, so the dealer said, use the small plates, then we were getting skips with the flats. Didn't have to buy more seed because the population evened out, but it did not yield better with the higher population.
It said at the time when we bought the 5100 White, The Most Accurate Planter In The World. not, if it can't plant flats. I've had a big problem over many years to get the seed companies to deliver my large rounds. Most of the kernels on a ear of corn are flats.
With my precision finger pickups, R1 or F2 plant the best
We use precision planting vset meters on harvest international bars and F2 seed works best for us. If not available then R2s
I’ve studied this for 4 years on my vacuum planter. I do small plots and have 150+ hybrids each year with all seed sizes and there hasn’t shown any difference in stands or yields
Rounds tend to plant better but also tend to have lower germ which offsets the planting advantage. Round seeds come mainly from the ends of the cob which, from the butt end, have been in the field the longest, and from the tip, have been exposed to the most environmental issues while flats are sandwiched nicely in the middle of the cob where they are protected better. Flat seed can last 5 or more years in a warehouse while rounds might last 2 or 3.
100% true. I use to work for Monsanto in Boone, IA (and central IL before promotion) When you see the seed production process from start to finish, you learn a lot and understand why a bag of corn cost $300 list price.
The seed corn Companies are backing away from +300 seed corn, competition. Lower 200 for triple stacked corn now.
R2work best for my planter
Precision V Drive Meters I like Flats the best F2 45 to 52 pounds.
