The 2020 version of PB 1768, Insect Management Recommendations for Field Crops (and pasture), is now available. The guide has gone through substantial revision this year and closely matches the content on the mobile friendly Disease and Insect Field Guides at https://guide.utcrops.com/. Hard copies will be available soon and distributed through county extension offices and at various educational meetings.
The annual West Tennessee Grain and Soybean Producer’s Conference will be held at the Dyersburg fairgrounds on Thursday, February 6th. Continue reading
Tennessee Certified Pesticide Applicators must take recertification training in 2020. The recertification training is good for three years. In addition, those who will be spraying Engenia, Tavium, FeXapam or XtendiMax on Xtend crops must take dicamba training in 2020. A new addition from the EPA will be the requirement that anyone who purchases, mixes or applies a paraquat-containing herbicide to take the “How to Safely Use and Handle Paraquat-Containing Products” training module. Continue reading
The 2020 Middle Tennessee Grain Conference will be held at the UT Space Institute in Tullahoma, TN on February 4th. Registration begins at 7:30 AM with the program starting at 8:30 AM. Participants are asked to pre-register at their local UT Extension Office until noon on January 31. Payment will also be accepted at the door. The $10 registration fee includes the program, refreshments, lunch, a conference cap, and a proceeding notebook.
Pesticide/dicamba re-certification will also be offered at 2:30 PM. Additional details, including the registration form are available at Middle TN Grain Conference Flyer.
The 2019 County Standardized Trials data are now available. This year, 58 hybrids were evaluated with 49 test locations being harvested. A great corn year brings the overall average across all locations and hybrids to 206 bu/ac. The tables are separated into 3 maturity groups, early <114 day, medium 114-116 day, and full >116 day corn. Hybrids are listed in descending order within each maturity across locations. UT recommends selecting hybrids that are in the A group statistically. Hybrids with *’s next to their name, have been in the A group for consecutive years. Two (**) indicate this hybrid has been in the A group for 3 consecutive years.
A special thanks to those companies involved in these trials for sending a great lineup. Thank you to all the county agents involved in getting these trials in and out. Thank you especially to the producers who allow these trials to be placed in their fields to provide all of Tennessee with a non-bias look at head to head yield comparisons across the state.
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
