How much yield is lost from planting 100 dAy corn in the middle of June versus 112 day on May 15

Question

Answer

New member cruising old topics. FWIW, I had some June 1st 100 day corn behind beans (in nc ks where that’s pretty agressive) make 143 when I’d be pretty happy with a 112 day number making 150 in wheat stubble planted the middle of May. But it was kind of a weird year..

Answer

We saw roughly a 40 bushel difference in 2018 between 109 day corn planted May 4/5 and 98 day corn planted  May 25 so I think ***'s guess is in the ballpark.  Your weed control should be much easier though, since you worked up the first flush by planting mid-June ;-/

Answer

I'll let you know this fall.   I'd like to see a row spacing plot on early, mid, and late planting.  Narrow rows utilize more sunshine in the northern plains.  Would that translate to anything with a late planting date with less sunlight to capture?

Answer

Here’s a stab at your questions using a couple rules of thumb. From maturity change 1 bu/ day , so 12 bu loss. Planting date 1 bu/day for last half May =15bu and 2 bu/ day for June= 30. =
57bu total? Thought it might be worse. Our mid May 110 day looks good, our early June 100 day is barely knee high.
