00:00 Um, at Zoba we are doing, we call it VPI, so it's a variety profile index. So it's either high, this would be a very high mm-Hmm. 00:08 Uh, VPI because of all the branching. So we put a trial on several of our new varieties, you know, per proprietary varieties in a low, very fertile spot. 00:16 Mm-Hmm. That would be a highly productive example. It also has a big ridge in it to be an example of what we call low VPI, main branch type bean. 00:23 Right. Okay. So we plant these beans out there and we observe them. Uh, that's what we're doing right now. 00:28 But then R eight will come actually get the pods off. How much percentage of the yield came from the branches? How much came from the main stem, okay. 00:36 On each of these varieties in a high VPI setting and in a low VPI setting. So then this, all this data will feed an algorithm in a 00:44 computer using seed select. You put your field in, it'll say this would be, this variety best matches the water holding capacity 00:50 and things in this field. This has a hundred bushel field potential. You want a high VPI where it has ability 00:57 to add the branches, playing a lower population, let it branch out and say 50% of its yields coming from branching, which I, we can put 01:04 that variety in the right spot. I noticed on this being early on that it was very willing to put branches on. 01:10 Yes. Very much so. It, it wasn't a last minute thing. I mean, look at how, I mean, those early no stacked the bottom, it stacked them tight 01:16 and it'd stacked them at the bottom and started right off at, you know, it started off well. One thing that, that, what we see is what I really try 01:22 to watch is, is so he's talking about these lateral branching. So I can stack these pods really good, 01:28 but it becomes so heavy these snap off easy. So in a lot of my varieties, they're a little more straighter than that. 01:34 So the more erect that you can get that coming out of the base when you pick your varieties and you get at like a 45 degree angle, okay, 01:40 the way they come in, you'll have a lot better chance of holding onto that. Mm-Hmm. Because a lot of times when we get into, you know, 01:46 when we're harvesting beans and they're kind of straight out like this and they put that weight on there, that thing breaks right off 01:51 and there's nothing that you can do. We've added calcium, we did all kinds of stuff. Now we did a bunch of stuff with Caliber. 01:58 I've told you about that in the past. You can add a lot of structural strength, but the first thing you gotta start 02:03 with is what he's talking about. When you get a branch that comes out at a 45 degree angle instead of way over here, that's gonna be a problem. 02:11 It's going to snap off. Do you think, uh, row spacing will influence the direction that those off? 02:16 I don't know. Come off. I mean, I've tried everything. Like I've done thirties, I've done fifteens. I do better with fifteens 02:22 and narrow rows than I do in thirties. The only thing that fifteens or thirties will do is they'll branch out this way. 02:28 So let's say that you're branching when you put it in a 30 inch row and your plants are like this, they'll branch into 02:33 that center of that row and center of this row. Mm-Hmm. But there'll be nothing else. But when you get into a 15 inch row, you 02:40 or a narrow row, they branch all the way around. Okay. So I can get a lot more out of them and that seems like I can get, I can space better. 02:47 I can stagger the, when you can space better. Every plant that comes up is at the same stage. And we talk about trigger points all the time. Mm-Hmm. 02:56 So it's very hard to get a trigger point when you got got one plant out there that's like this and it's bushy 03:01 and the next one you got out there looks like this. It's just a single stem. Well, guess what? This one and this one, they're two different stages 03:08 of the crop and you're staging to make a trigger point at one specific time. And guess what? You got about three 03:13 or four different stages out there. So how are you going to, how are you gonna do that? It's almost impossible to do. Mm-Hmm. 03:19 So that's why with fifteens, and we use precision meters on, all of them are, and we pay really, really close attention 03:26 to spacing the beans perfectly. So that's when you can get into a point where you start dropping back when you can start 03:32 stacking nodes like you done. And you can have plants that branch out like these VO beans have done. 03:37 When you get into that situation now you can start spacing 'em correctly. You can start hitting trigger points correctly 03:43 and you can start really maintaining yield every time. You know, I've been talking to Chad about this for a while and he's done it this year. 03:50 So he actually made four different applications of, um, pgs. So every time you put a PGR on, you stimulate this plant, 03:57 you wake it back up and it'll shoot a whole nother set of blossoms. Mm-Hmm. A whole nother cluster. Well, if it does that, 04:02 but you don't have some groceries and some foliar that go on with it, first of all, you gotta have a plant that'll do it. 04:07 Mm-hmm. First of all, and obviously this plant will do stuff like that, but when you do that, 04:11 you gotta have the groceries that it can go ahead and facilitate what you asked it to do. And that's where people mess up. 04:16 They think, well, I'm gonna put a PGR out with a fungicide. And all of a sudden you see a cluster, 04:21 a little cluster come out, you are like, oh yeah, it worked well then it all died off. Or the blossoms died 04:26 or the, you know, it just didn't have enough to finish it off. So you have to, it's a systematic approach. 04:31 How many times have we said that, you know, these things work in synergy with each other. So that's kind of some of the keys 04:37 that we see in high yield and soybeans. Now when you're talking about feeding at that later, if a guy's pushing them, what would be a priority? 04:43 Are we looking at a potassium or are we looking at a micronutrients? Well what, what kind of feeding are we looking at? 04:49 Well go back to, you've been taking tissue samples for quite a few years, right? Mm-Hmm. And you've taken tissue samples at this point. 04:55 Like let's say that you want to go back to this point and you wanna do something, go back to your tissue samples in prior years 05:02 and look at what you were missing. If you can get ahead of what you were missing at that next stage. 05:07 Mm-Hmm. That's what makes the difference. Okay. So not for everybody. I'm not saying that. I mean, it's gonna work. 05:13 Certain products are always gonna work. Cowboy, for instance. Mm-Hmm. That's always gonna work. 'cause you need calcium in the plant. 05:18 If you're trying to build structure, you also need boron. It's got both of 'em in it. 05:23 It's going to add to stem, wall press, um, stem, stem wall strength. It's also gonna help you 05:28 with pollination bo not borons gonna help you with pollination. The other things that's going to help is potassium. 05:34 Potassium is gonna help fill the seed. It also helps translocate things up and down the stem. It also helps in droughty conditions 05:40 because you're able to get some stuff pulled up outta the ground. Those are some of the things that happen. 05:45 Now keep in mind there's other things that happen. You have to have a micro in there because you have to be a balance that plan. 05:50 Mm-Hmm. So that's the balance that comes in with a micro pack. And it can be a certain micro pack, 05:54 but that's where I'm saying go back and look at your data because there's gonna be certain things in your soil type 06:00 that's gonna be very different than mine. It can be vastly different. And that's why if I say, Hey Andy, try this micro pack. 06:07 And you say, well, it never worked for me. How many times have you had a say, yeah, that micro pack doesn't work. 06:11 Well, maybe it wouldn't rate micro pack for your dirt because your soybean has a certain ground that it's in. It's on your program. 06:19 And your program is very different from that guy's program over there. Mm-Hmm. Just across the street Yeah. 06:24 Is very, very different. So if you don't know those things, you're not gonna get a good ROI on that. 06:28 You want to have a sugar in there that sugars give, give the plant energy. And you also want to have phosphorus in there. 06:35 So PGR kicks it in the rear end. Mm-Hmm. Potassium will help get stuff into the, um, the bigger seed size and, and that sort of thing. 06:42 And then you're gonna have phosphorus, if you have a, for me, you can put a heavy load of phosphorus in. Now I'm a little more phosphorus 06:48 deficient than what you probably are. I struggle a little bit with getting in the plant, but phosphorus gives a plant a ton of energy. 06:54 So all these things go together. The other thing is, is like, make sure you put a humic and fulvic blend in there. 07:00 And I know I'm throwing a lot at you. Mm-Hmm. But when you talk about high yield and soybeans, all these things make a difference. 07:06 So if you put a fulvic in there, it supercharges what you just put out there to work better. It drives all of them into the plan. 07:12 And every time you make that application. So, like I was saying, Chad did this. He made one application, then he did another one 07:18 where he did two applications. He did another one where he did three, another one where he did four. 07:22 And he said, every time that you stepped into it, you could exactly see boom blooms. It filled out the pods. Boom. 07:29 More blooms that filled out pipe. So he did that and he stacked 'em four different times and he created four sets of blooms 07:36 that he would've never got before. Now when he was doing that, was he using a, uh, like the beans in south to use the uh, predetermined? 07:43 No. He or was an indeterminate be. Yeah. These were indetermined. Okay. So you can't really, once you use, like, you can't really do 07:49 that with a determinate bean. Mm-Hmm. 'cause the determinate beans are, they're gonna make what they're gonna make and they're gonna be done 07:53 and they're, they're gonna be done and you're not gonna change anything. You have to use it in determinate bean. 07:57 That's, you know, you gotta keep it in reproductive. And you can do that with an indeterminate bean. Okay. And maybe you can do some of these things 08:03 with a determinate bean. I don't know. 'cause I don't ever fool with 'em. Okay. That's way we don't have, we don't deal with that. Yeah. 08:08 I mean they just make what they make. Yeah. Like they do it all at once. Yeah. Not like this. They grow bloom and that's it. 08:14 They grow bloom and they're done. Yeah. You would know that. Not us. Yeah. Yep. I mean, it's absolutely true. 08:19 The indeterminate I've seen in the past, like we come into, they talk about a bad weather situation. 08:23 They flowered, they got hot and dry, no rain, abort, abort, abort, abort. And the plant just kind of went into hibernation mode. 08:30 And the conditions changed. Uh, it was in late July about this time of year. The, the weather became perfect. 08:35 The soybean plant does have the ability to re-bloom again one time. So it can it, yeah. 08:41 And it can re-bloom again now won't be as ideal as it was, you know, the original bloom. Mm-Hmm. But it's better than, you know, 08:48 just having dead plants out there with 10 bushel beans or whatever. Right. So they do have the ability and, 08:52 and determinate to kind of wait until things are right. That this kind of wait, oh, conditions are good and they take off again. 08:58 So you want to have everything there when it's ready to take off every year.
