Corn double rows?

PJH · May 11, 2017

Saw a few fields with corn sprouted and 3 inches tall today. It was in double rows, maybe 4 inches apart. I first thought it was something about the headland, maybe a double pass or something, but no, the whole field was double rows. That's not how Dad did it - what's going on? Is my old two row planter gonna become obsolete?

I'm sure a tractor was involved - to keep it on topic.

They do that to increce the plant population. To get the high yeilds you have to get in the 40,000 or so population and some theory says double rows are the answer. Hust another part of what the farmer is doing to further agriculture putting food on the table like it or not but he is doing a super job give him all the credit. We learn by doing

I saw a few fields of beans planted that way last year. Probably trying to maximize yields.

There's a fair amount of that over east of here toward the thumb. A company called Monosem builds twin row planters.

Brother has a twenty inch twin row Great Plains planter through a Stine seed deal. Has really helped his yields on marginal ground that's not irrigated.

This is interesting, I wonder how the yields work compared to the extra inputs.

The idea is to increase the spacing between plants with higher populations and still be able to manage and harvest with a standard row head. Twin rows are 8" apart and evenly staggered to get maximum spacing. Twins are on 30" centers, not needing a 20", 15", or Kemper head.

Is it like stitching on the rows?

Also once heard a guy say, when? harvesting 15" rows, everything in front of you is moving, driving you bonkers trying to stay on the row, but with twin rows you can see the space between to keep on track. Probably before GPS was in common use.

Some larger farms in central MN have been using double rows for corn and beans for over five years.

Sorry about the duplicates, was giving me an error code.

I first heard about twin rows when I went to a planter clinic in eastern PA 10 years ago, but I think they've been used some for years before that.

Neighbor has done that for quite a long topi me now. Great Plains planter I believe.

You can harvest with a regular corn head, each row bends in just a little to work.

I had a bright idea this year to try twin rows on some acres , at first thought id do 100 with a 12 row and double back about 7" off the old row, well it was close to dark when I started and did about 14 acres and wish I hadn't started , I did wind up around 39 k pop and im glad for the most part from the road the rows run with the road so the general pop cant tell how bad I screwed up lol, but when the corn pops through im afraid it may look like its stiched rows instead of double lol, I had excellent fertility in the field and lots of manure so im fairly optimistic still.

Sigenta raised seed corn in a field down close by. The only time I saw double rows was every 5th row, the male row. The other 4 rows were detasseled and harvested the seeds from. The male row was ran over after pollination was complete.

I noticed one of the BTO's near me has started doing double rows - on 30" I think

So how much additional yield do you expect?

I was reading up on soybeans and what I was finding was the difference between 30" rows and 15" rows was only a single-digit percentage.

I wouldn't think that there's any advantage to bean yield, only corn. If you have a twin row planter but not split row (15") or drill, why not.
