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.
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.
Please see publication W 900, Hemp Variety Trials in Tennessee, for information about the performance of many hemp varieties in 2019.
Our county corn trial numbers are still rolling in, but results are up for the small plot trials performed at the University of Tennessee AgResearch and Education Center locations. Results can be found at search.utcrops.com/corn-grains as both web tables or as a downloadable excel file. These tables will be updated with county data as soon as that is available.
AgResearch and Education Center (REC) plots are 5 ft (2, 30 in rows) by 30 ft and are replicated three times per location. Total number of entries was on par with most years, totaling 89 corn hybrids, representing 14 company/brands. Continue reading
Our 2019 Tennessee corn silage hybrid trial report is now available on search.utcrops.com/corn-silage. We had fewer hybrids than usual this year and all produced similar yields, averaging 8.4 tons/ac dry weight. Differences did show in terms of quality, however, with some hybrids producing significantly higher milk/ton. Mean separation (MS) values help us identify statistical differences between hybrids. Look for the “A” group to identify hybrids that were top performers within each trait. If looking at the online tables, be sure to scroll right to see all of the quality and agronomic traits evaluated. Online tables can be found here or download the pdf and/or excel tables.
In Tennessee, corn harvest is beginning and soybeans will be right around the corner. Time to start talking about cover crops, in particular, what options are best for your cropping system. Cover crops offer many benefits to cash crop systems, including weed suppression, nutrient credits, improved soil health, pollinator habitat, and more. Many species can be used as cover crops but each differs in the ecological benefits it can provide to a system as well as in its adaptation to production regions in Tennessee. This adaption is highly dependent on management practices, especially time of planting. A species selected as a top performer when planted after corn may not do so well in a system following soybeans, where cover crop planting is two to four weeks later. Planting a poorly adapted species reduces your return on investment in a cover cropping system, so let’s talk about what works in Tennessee. Continue reading
Final results are in for our 2018 Tennessee soybean variety trials. The pdf and an excel workbook with all tables are available for download here. Be sure to also check out search.utcrops.com, where our mobile-friendly tables will be updated over the next week or so.
