Hello, I’m Billy Streich with ALCIVIA out of Whitewater and I’m Jedd Agnew ALCIVIA out of Genoa City.
Today we’re going to go over some stand evaluations and how to take a proper stand count the first thing we want to talk about is growing degree units. So, a growing degree unit is taking your high temp of the day maxing out at 87 degrees and the low temp of the day the lowest being the low of 50.
So, you’ll take those two temps add them together, divide it by two, and then minus 50 to get how many growing degree units you got for the day. So, for germination you’re looking at you’re, you’re going to need around 50 to 80 growing degree units. V1 you’ll need anywhere from 100 to 125. V2 you’re looking at 150 to 200, and v3 you’re looking at around 300 to 350. V3 they call the ugly stage due to the corn coming off from living on that seed to now living off its nodule root so it might get a little ugly looking, but that’s your early emergence.
Now, I’m going to send it over to Billy strike to do some stand evaluation.
All right in this field here we have a 20-inch row spacing in this corn field and a good way to help determine our plant population here early in the season is doing a stand count. So, in this 20-inch row spacing corn we got the tape measure laid out here and what we got after counting the stands here on both sides of the tape measure we have a 32-plant count so we’re at 32, 000 for a plant population. And the grower was planting at 34, 000 so we did have two plants here that didn’t make it due to either just early season stress or maybe the planter skipped.
Then we can take this tape measure and be able to evaluate our stand counts from the planting we did this spring, and we can use this as a tool to make good decisions for the rest of the growing season.
If you would like to have a stand evaluation in your field be in touch with your local ALCIVIA agronomist and we can go from there.
