The 2015 growing season marked an important year for 360 Yield Center, as we conducted multiple field trials throughout the Corn Belt. We shared a few initial hand-check yield results at our Proving Grounds field day in August, and now, the harvest data is in, and we’re eager to begin sharing results.
This first trial was conducted in central Illinois and aimed at comparing N timing and placement with 360 Y-DROP versus a coulter. The coulter N application was done at V6 during the first week of June 2015. The 360 Y-DROP N application was done at V16 during the first week of July 2015. Both sidedress applications were 150 lb. of N. In both trial systems, 100 lb. of N was applied as a base application on the whole field, including 30 lb. with the planter (2×2) and 70 lb. of weed and feed worked in with a vertical tillage tool just prior to planting.
In the image below, you see the yield map of the test strips. The aerial photo is above.
Additionally, there were areas in the field with heavy rain and poor drainage. In those stressed areas, late-season N provided a huge yield advantage.
For more background on the trial, take a look at Gregg Sauder’s presentation at Proving Grounds. Also, stay tuned for our 360 Yield Center Yield Book, an in-depth analysis of our 2015 field trials, coming soon in early 2016.
