Defoliation Strip Trial Overview, insight to performance in cool conditions

Author:  Comments Off on Defoliation Strip Trial Overview, insight to performance in cool conditions

 

On September 18th, we applied a defoliation strip trial in Gift, TN.  The field was 85% open with juvenile and mature leaves present.  As you likely recall, this was immediately before a cold snap.  Night temperatures for the next five days were 54, 55, 55, 59 and 57. In this blog, I describe the concoctions applied, share a brief video of the results 13 days after the initial application, and highlight a few important take-homes from the video. Continue reading

Cover Crop Variety Trial Results

Author:  Comments Off on Cover Crop Variety Trial Results

Are you thinking about putting in a cover crop this fall? While cover crops can provide many benefits, picking the right species and varieties for your system is critical to maximizing those benefits. Check out our 2020 cover crop variety trial results for a head-to-head comparison of 60 cover crop varieties at three TN locations.

Cover crops were planted in fall 2019 and evaluated for a number of important traits, including fall and winter canopy cover, biomass at termination (April and May), and estimated nitrogen release.

  • Top-performing cereal varieties, including Bates RS4 cereal rye, NF95319B cereal rye, NF 97325 cereal rye, NF99362 cereal rye, and Wintergrazer 70 cereal rye, excelled at providing fall canopy cover and spring biomass,
  • Top-performing legume varieties, including AU Merit hairy vetch, Survivor winter pea, Purple Bounty hairy vetch, Patagonia Inta hairy vetch, and WinterKing hairy vetch, excelled at providing winter canopy cover, spring biomass, and nitrogen release.
  • Top-performing brassica varieties, including Viva hybrid brassica, Digger radish, and Smart radish provided above average fall and winter canopy cover at the East and West TN locations.

More information can be found in the full publication or excel tables. A virtual tour of the plots was also presented at the virtual Milan no-till field day and is available here.

Defoliating in volatile weather conditions (is this the end of October?)

Author:  Comments Off on Defoliating in volatile weather conditions (is this the end of October?)

If you trust the forecast, volatile temperatures should increase over the weekend before again falling into the upper 40s by the middle of next week.  Thanks, 2020.  Unfortunately, we do not have great options after Sunday and fields in West Tennessee are wet.  This blog covers the mixes I’m running prior to Saturday afternoon, Sunday through mid-week and thoughts on whether or not that green, soft boll will mature before a freeze.
