In-Furrow Fertilizer vs. No In-Furrow: Boosting Corn Yields by 28 Bushels per Acre in Irrigated Fields
8 Oct 247m 46s

A trial comparing in-furrow and no in-furrow applications on corn was conducted to assess yield differences under irrigated conditions. Despite facing drought stress in June, irrigated corn showed significant results.

00:00:00 Hey y'all. Today we're out here harvesting different corn plots. We've got our nature's plot that we've pulled some ears from 00:00:07 to so that you can see a visual for it to go along with when we get our results, hopefully the next day or two. So everything here was planted April 26th. 00:00:17 It went the entire month of June window, no rain. This is irrigated corn, so it was watered, but we did deal with the creek level getting pretty low. 00:00:25 Towards the end of June, about mid-July, we started getting rain again. So this is solely, solely got irrigation up front on it. 00:00:33 So what we're looking at is we had um, 15 pioneer, 1511 that we planted and we used no in furrow on it. And then everything else throughout the year was the 00:00:43 same for the whole plot. Your all of our spray applications were the exact same for the no in furrow and in furrow. 00:00:50 Both of these had two by two put on it. Um, you'll see a list here in just a minute of what was used on it. 00:00:55 So we're comparing our no in furrow to our in furrow on the same variety of corn and hoping we can maybe see a difference in our yield at the 00:01:03 end of what that one piece of the puzzle does for us. Some people don't have the ability to do in furrow on their planters. 00:01:11 Um, we're very blessed that we have that ability to do it. So we're hoping to see if 00:01:17 using the infer system is making a difference for us at the end or if we're just spending extra money that's not really making a 00:01:23 difference for the yield forest us. So we'll see here we went out in the field and every 10 plants we pulled a ear. 00:01:30 So this is just what we got. This one looks pretty, pretty rough, but that's what we got and we didn't replace it with another one. 00:01:38 We just went every 10 and pulled it here for you to see. So our stream ag field day, if you had opportunity to come 00:01:46 to it, I know Hurricane Tropical Storm, Debbie made it pretty soggy event. Quite eventful. So they wasn't that many that was able 00:01:53 to venture out, but about 84 of you did. I was impressed with that number, but um, you didn't get opportunity to go out to the field. 00:01:59 So we want to kind of go over what we've done out there and um, and what the nature's team brought to challenge us with and see how things would work this year is with infer, 00:02:11 it has zero infer in it. It has 24 s nitrogen on it, and that's pretty much it. The way these ears were obtained two weeks ago when we was 00:02:21 harvesting the plot, they went to the 10th ear on the same row of the planter and pulled one ear, then they went 10 more stalks, 00:02:29 then they pulled the next in. And so this is 30 foot right here, it's nitrogen on it and then it's got some Fs on it. 00:02:36 Nothing else put in with a planter. This here has got the nature's program with their infer, their, uh, fertility in the tub by two 00:02:47 everything on it. So we got a yield of 287.4 bushels here and we got a yield of 258.8 bushels here. 00:02:56 These were at a harvest population of a little, little over 34,000. They're completely dried down now. 00:03:02 They was harvested around 2220 3% moisture and we've kept these ears to let 'em dry down as much as possible so we can get a true test weight of 00:03:12 what it'll be without going through a commercial drying facility. The test weights is pretty good on what I've seen so far in 00:03:18 that 62 63 pound range. This right here is like most, most planters do, uh, a lot of the planters out there don't have infer on them. 00:03:27 They don't have two by two. This was two by two nitrogen applied and that was it. No other additional uh, products in that nitrogen 00:03:36 and we're at 258.8 bushels. So we got a 28.6 bushel advantage with this program. And as you went across the field, the dr, the heat 00:03:48 that we had, we had some stressed areas and the stress really showed up in this right here where we didn't see the stress 00:03:54 over here in this full program where we really protected the plant through the roots from the inside out of the plant, 00:04:01 it made it a lot more stress worthy during those high times. So what all was included in this was in our infer we had 00:04:08 four gallons of first down, one quarter of face off, we had a pint, a link pe, we had a pint, a 3% calcium and we had our four ounces of our PGR 00:04:20 and the one ounce of a nano X exp in here and this one here. And then we also had 00:04:27 and our, we added two gallons of throwback plus a quart a sides swipe and our neutral charge and two quarts of IC in this as well. 00:04:38 Our foliar passes, we left them pretty much the same on both of them. That way we could really identify in this planter pass, 00:04:47 how much is this, this component alone, this infer and the tuber two, what does that bringing to the table? So the foliar passes were the same on it, 00:04:57 so we growed some pretty good corn foliar applying these products right here. Our triple option, our finish line 00:05:05 and our uh, throwback in with our top dress S nitrogen and kfl. We put some extra potassium out there, which is a big deal, 00:05:13 a cortic side swipe. And then our foliar fungicide when we went in there and all these is with normal trips that we're going. 00:05:20 We didn't add any extra trips. This is what we would normally do. We'd come back V four, V three, V four, 00:05:25 were getting our post emerge application out there. We preferred that one at V three but it, it just, the way it worked out with the weather, 00:05:33 the ground was a little wet. We didn't wanna mess it up with a sprayer. So we held up and then it just turned into absolute drought. 00:05:39 The R four was late season. We're trying to with that R four, that late season. We're trying to get that kernel weight in there 00:05:48 and that's, we're wanting as much seed size and kernel weight as we can get. You know, it's pretty good size seed on here 00:05:55 and boy, she's dry now. She just popping off our good. So you can see the kernel size there is a whole lot bigger now. 00:06:02 So you're probably looking at about 14%. It's dried down and, and you know the test weights on this 00:06:08 is on up there pretty good. 62 63 pound. I hadn't tested this actual ear obviously, so that's some pretty impressive results. 00:06:16 We getting things right to start with when that corn's coming out of the ground. So again, this is had zero infra in it whatsoever. 00:06:25 It just had plain 24 s nitrogen and then this right here was the full program and at planting both these had the same foliar on it. 00:06:35 Again, the same foliar treatment, same irrigation treatment, everything the same At the end 00:06:43 of the day we was 258.81 bushels on the no infer this is irrigated corn and 287.4 bushels with the full package. 00:06:53 You might say, I hope this helps you a little bit in making your decisions for next year. 00:06:59 This is something we've been seeing for several years now. Yes, a little extra work, having that liquid on your planter 00:07:06 and having to have a tender trailer. But at, at 25, 28 bushels, I think you can justify putting a little extra in there 00:07:15 if that's what you want to do. And for us here in North Carolina, we don't like to grow more acres. 00:07:20 We like to grow more bushels. So you know, other areas of the, of the US it works great for you that you can, you know, maybe not spend 00:07:29 as much time on each acre, but you got more acres you can farm, but not, not many areas is like that nowadays. 00:07:35 So we gotta be very efficient. 00:07:37.145 --> 00:07:40.885
