New planter already?! Seems like not long ago I was supposed to help put disc openers on that one...0I've been thinking the same thing. Looks like a different planter next year and wondering about the switch from 30" to 20". Would require a different header and probably a non-chopping one because of the drive on my feeder house not being able to run a chopping head with 18 rows though. Asked some seed reps the other day and they figured if pushing populations(I was at 34K this year) then a potential improvement in the 20". Some neighbors running 20" and apparently having good luck with that. Downside is have to spray across the rows instead of down them, but weed control should be better as a whole. Could then use same planter for soybeans if I ever decide to grow them again...
This is pretty much what occurs here too. Add in this area low resale value of 20" simply because not many do it and more corn lodging in 20" rows. I've said before in my area corn hybrids are not yet bred to excel in 20" rows.Some guys have switched from 30 to 20 inch rows around here and yield wise it doesn't seem to make any difference. Their higher populations and large amounts of trash after they are done harvesting is a turn-off for me. Not worth it for the one out of 10 or 15 year chance all the stars align and 20" row corn actually yields higher.
Most of the guys running 20" have gone to tracked tractors too so they can run 16" tracks. Pizza cutter tires have zero floatation and it always seems to be wet here.
I still think 15/30 split row is the way to go. 30" corn yields just as well as 22" and 20" around here and canola and beans in 15" works just fine. The only major downfall to a split row is when you're doing corn the extra row units being locked up is additional weight.
Go to harvest though and an 8 row or 12 row corn head are the same width with 1/3 more moving parts wearing out and adding weight.
Just my observations, I wouldn't even consider 20" anytime soon unless it was yielding substantially better than 30"
Yeah if there was a big difference in residue then why would the yield not be different as well??? Someone is gonna have to explain that one to me.I'd venture to say that if you are just talking about total field residue from 30" corn to 20" it would be fairly comparable. 35000 plants is still 35000 plants no matter the row spacing. That's my gut instinct.
The only time residue would come into play would be whats going through the combine in a 8-30" head compared to a 12-20" head. Not sure if there be an increase in plants going through or not.Yeah if there was a big difference in residue then why would the yield not be different as well???

Plant numbers wouldn't change there.The only time residue would come into play would be whats going through the combine in a 8-30" head compared to a 12-20" head. Not sure if there be an increase in plants going through or not.
