Farming Video | Planter Flag Test for Emergence | XtremeAg

30 Apr 25 • 1m 21s

Jacob and Grace from Live Oak Ag conduct a planter performance evaluation using a flag test to assess emergence timing and its impact on yield. They classify plant emergence into four groups using color-coded flags over four days, highlighting how early emergence (days 1 and 2) generally results in higher yield potential, while later emergence (days 3 and 4) leads to smaller ears and reduced return on seed investment. They plan to revisit the test in August to analyze ear sizes and validate emergence penalties.

00:00:00 Hey guys, this is Jacob. I'm Grace. And we're with Live Oak Ag. Today we're looking at planter performance 00:00:08 through a flag test and looking at, at emergence and emergence penalties based off of different emergence dates. 00:00:14 Grace, what do we got here? We got four different color flag. What do they mean? 00:00:19 Green means day one, blue means day two, yellow means day three, and red means day four, Right? And what we're 00:00:28 looking at there is the first plants that came up and some of the second plants that came up, they're going to give us the most return 00:00:35 on that seed investment. They're gonna give us the biggest ears, the best yield. When you start looking at day three 00:00:41 and day four, they're gonna be the smallest ears. Give us the least return on investment. What's some other things that might happen? 00:00:46 You think that day four plant might be a weed? Because it's not the same size as day one and day two Maybe. 00:00:52 So we're gonna see what happens whenever August comes around and we get ears out here. We're gonna come back out here, mark these ears, 00:00:58 take 'em off the plant, carry 'em out, and we're gonna look at 'em and see what the different sizes are, do some stand count 00:01:03 or do some ear counts and see where we're at. See if day four is really, is much of a weed as a compared to the day one and day two plant. 00:01:11 So we'll see in August, grace will be here with me 00:01:14.205 --> 00:01:15.645
