Results from 2017 Variety Trials in Mid-South and GA
State cotton specialists in Tennessee, Mississippi, Arkansas and Georgia have released results of their 2017 state variety trials, in time to help growers with variety selection for the 2018 crop.
“The 2017 Tennessee Cotton Variety Trial Results publication is now available online,” says Tyson Raper, Tennessee Extension cotton specialist. “This document contains detailed results from all harvested trials in the 2017 University of Tennessee Cotton Variety Testing Program. Trial results include six Official Variety Trials, three large plot, replicated strip trials, and 14 County Standard Trials scattered throughout Tennessee’s cotton producing counties. Additionally, in-season plant measurements and multi-year yield averages were reported for the OVTs.”
Preliminary results from 2017 Mississippi trials are also available online, including Small Plot Official Variety Trials and Large Plot, On-Farm Trials, reports Darrin Dodds, Mississippi State Extension cotton specialist. The small plot trials were conducted in nine locations (six dryland, three irrigated). On-farm trials were conducted in 17 locations.
According to Bill Robertson, University of Arkansas Extension cotton specialist, several new varieties featuring new technologies are worthy of a look in 2018.
“Variety selection is perhaps the most important decision a producer makes,” he says. “Our planting recommendation is that roughly two-thirds of your acres be planted with varieties that are proven on your farm. Of the remaining acres, limit new varieties to no more than 10% of your total acreage. The remaining 25% should be dedicated to those varieties in which you have limited experience. This strategy provides stability while allowing for evaluation of new varieties.”
Results from the University of Arkansas Variety Testing Program, conducted by Dr. Fred Bourland, can be found online.
Results from the 2017 University of Georgia On-Farm Cotton Variety Evaluation Program are also now available online, says Jared Whitaker, Georgia Extension cotton specialist.
“Data will be updated with fiber quality information, and additional information will be added when results from the UGA SWVT OVT results are published,” he states.
