OBSERVATIONS
SUMMARY
The early burndown treatment was applied on June 5th prior to planting on June 12th. Crimper termination occurred the same day as planting as the 2019 planting season was delayed due to excessive moisture. The crimping conditions were more moist than preferred, but the rye killed quite well as it had certainly reached anthesis. In the future, the goal is to move the burndown, planting, and crimping dates earlier in the season. Field conditions did not allow an ‘‘early’’ burndown application (early May) like was planned for this trial and all residual herbicides were pulled out in exchange for using the Xtend platform. Seeding of cover crop rye at a rate of at least 70-100 lbs continues to be a best practice based on observations.
•
No statistical difference in yields or moistures were observed in this trial for the second year in a row.
•
Repeating this trial will add to the validity of the results.

TOOLS OF THE TRADE
PROJECT CONTACT
This tool needs to have blades arranged in a Chevron-pattern (curved) so that it will roll smoothly without throwing soil. Several manufacturers make these in front-mount, rear-mount, or pull-type designs. The crimping effect terminates standing rye that has flowered and lays it down to create a weed suppressing, moisture retaining mat.
