south central IOWA | Just out looking at crops today and got a couple of pictures in the area of when I took the video planting. http://www.youtube.com/watch?v=ylaL-TW6BOg&feature=g-upl
This is bottom ground that is Zook soil. If you know anything about Zook then you know it doesn't drain well. This is off to the best start that it has been in quite a few years. Very impressed with the emergence. Maybe it's the hybrid, IDK.

Independence OR | What population? Are those 36 or 30in twins? That corn is looking really good. What is your starter program? I am a twin rower as well, this is my fourth season planting on 30 in twins with a Monosem. Will never look back!!!

Schlegel Farms, Hagerstown Indiana | That looks nice.
Also have to hand it to who ever took the video from the four wheeler ....I'd of had the front tire,,,the ground,,,etc.

Central Nebraska | That corn looks really nice. Your planter does a good job making the "diamond" pattern. |

south central IOWA | They're 38" at 34,400. No starter around here. This field had 175lbs of anhydrous applied last fall. It might be possible 38" rows receive the most benefit from being twin rows IDK. They seem to have really helped our yields but haven't done any tests. Have a neighbor on 20" and of course one with 30" and am hoping I can talk them into doing a test plot next year. |

south central IOWA | Thanks. It's pretty much a guessing game though with how sensitive the drive chain is. You really can't tell until it comes up how well it done and then it might be too late. This was the last field to be planted so we knew from other corn that was up that the adjustment was off. Hopefully it will still be the same for next year.

NW Missouri | Corn looks good. That is an understatement on Zook though. Near 0 for drainage. NRCS soil scientist and I took some probes recently on a Zook. Same profile 48 inches down. Best way I have had to handle it was to work it in the fall and stale seedbed plant it in the spring. It is always the last field I plant. |

South Central South Dakota | What kinda yield bump are you seeing outta twins? I have been trying to find more info out about it not sure if it is worth the switch in my area. I went from 36in rows down to 30in rows to now varible rateing my seed and have seen great results that way just not sure if going to twins would be a worth while step and if so to stick with 30's or go back up wider.
At 36in rows we planted 18,500-20,000. On 30in rows i went to to 22,500-24,500 and now with my varible rateing im going from 17,500-29,500 across a field but many times with a average of 22,000-23,500 |

From the research I have done there isn't a huge yield advantage at all. On average it looks to be about a 3 bpa advantage over 30" rows. To get the best yield response from twins you need to bump populations. If you plant 5k thicker the extra seed cost wipes out your 3bpa advantage not to mention the higher equipment cost.
Twin rows look nice but I don't think it will ever be used on a big scale.
http://corn.osu.edu/newsletters/2010/2010-07/twin-row-corn-producti...
"One major seed company reported that in 2009 twin rows out yielded 30-in rows at 16 of 20 locations with an average yield advantage of 3 bu/A. However another company found no performance advantage of twin rows over 30-inch rows based on 2005-2006 studies. Both of these companies compared twin rows using different hybrids and a wide range of plant populations."

Central Nebraska | I don't know that it would be a huge advantage on 30" rows. Where it does make a difference is 36" rows. I can push the higher population on my 36" rows with my twins that the 30" guys get and I don't have to change any of my other equipment. If you are already on 30" rows, I don't know that you would be happy with a change. |

This field was chisel plowed last fall which was the first fall tillage in a few years. I know stale seedbed has been discussed before and maybe I wasn't paying attention then but what is your way of calling it a stale seedbed? Just trying to figure out if we done something this spring that helped some (as in a stale seedbed). |

NW Missouri | Stale seedbed we used was to work and level it in the fall or very early spring and then let it sit until ready to plant. Whenever I tried to work it in the spring I had to catch just the right day and not make a bunch of marbles. Planting into the seedbed which has sealed over was a piece of cake and I have gotten the best stands overall using this system. |
