The 2021 Tennessee Cotton Variety Trial Results Publication (PB 1742) is now available online.  Included within these results are ten large strip trials (CSTs) testing 15 XtendFlex commercial varieties, three large strip trials (CSTs) testing 5 Enlist commercial varieties, and six small plot trials (OVTs) testing 41 experimental and commercial varieties. Special thanks to all of the agents and producers who helped generate this data.  Additionally, thanks to the USDA Classing Office in Memphis for assisting with this effort.  If you have any questions on location response or variety placement, please do not hesitate to reach out directly to your county agent.

The 2021 Tennessee Official Variety Trial (OVT) Results are now available online.  By clicking the image above or the pdf below, you will be directed to trial information, an overall OVT average table, and individual average tables for five of the 2021 OVTs.  Continue reading →

Preliminary data from the 2021 TN Cotton CSTs is now available.  We are releasing an average table for the XtendFlex trials and the Enlist trials today and hope to release the quality and individual location results in the near future.  Keep in mind the XtendFlex and Enlist trials are conducted separately, so direct comparisons between tables cannot be made from this dataset.  Also, stay tuned for the OVT small plot trial data average table which includes 41 commercial and pre-commercial varieties.  Continue reading →

It’s a challenging time for crop producers to manage input price risk. Input prices for fertilizer, crop protection (chemicals), machinery, fuel, labor, rent, and insurance are up substantially compared to last year at this time. Additionally, availability and timeliness of delivery are a major concern. Fertilizer prices highlight this dramatic increase in the cost of production (graphs above). Most common fertilizers have more than doubled compared to last year. As such, producers are seeking strategies to reduce input costs. Two recommendations, as a starting point, are soil sampling (know what you’ve got) and crop selection (know current relative cost and revenue relationships for commodities produced on your farm). Unfortunately, there is no “silver bullet” to mitigate rising input costs and availability concerns. So, producers will need to be creative in their approach and consider numerous strategies.

Rainfall pushed us out of the field today and it looks like we may not get back to spraying until early next week; it is generally best to not apply harvest aids in front of a guaranteed rain.  In this blog, I cover defoliation concoctions as we move into cooler temperatures next week.

I dug through my closet to get a jacket this morning.  With cooler temps creeping into the forecast, calls on defoliation timing, products and rates have really picked up.  In this blog, I highlight results from the earliest defoliation strip trial we’ve applied in 2021, share a few concoctions that I’ll be running on the earliest cotton here in Jackson next week,  circle back on boll maturity and give a couple of additional thoughts on what we will likely face in the coming weeks.
