As cotton producers across the Texas High Plains begin preparing for a new season, Texas A&M AgriLife Extension Service specialists are providing up-to-date information on the performance results of commercially available varieties across the state during 2020 trials.
The annual Replicated Agronomic Cotton Evaluation, or RACE, trials conducted by AgriLife Extension specialists and agents are sponsored by Cotton Incorporated, Plains Cotton Growers and the Texas State Support Committee. They test varieties offered by seed companies, such as BASF, Bayer, WinField United and Americot.
“Although 2020 was a tough year, variety results are still valuable when making 2021 decisions,” says Dr. Jourdan Bell, AgriLife Extension agronomist, Amarillo. “Our 2020 results provide producers an opportunity to evaluate variety stability across multiple management and production environments. By comparing variety performance across multiple locations and multiple years, producers are able to select stable varieties for their farms.”
Combined South Plains and Panhandle results can be found on the Texas A&M College of Agriculture and Life Sciences Department of Soil and Crop Sciences Variety Testing site — http://varietytesting.tamu.edu/cotton/.
South Plains 2020 Trials
In the South Plains, the 2020 season was riddled with challenges in the field from start to finish. Lack of rain was the main bottleneck, says Murilo Maeda, AgriLife Extension cotton specialist, Lubbock. With warmer temperatures early in the spring, some farmers planted early. What little moisture was available then, however, didn’t make it very far.
The lack of adequate planting moisture resulted in a great percentage of dryland fields failing to obtain a good plant stand, if they emerged at all. Those with access to irrigation fared much better overall, but producers also struggled in places where water availability was limited.
In-season precipitation was scarce and tended to favor areas east of Interstate 27. A cold front early in September and two days of ice and snow in late October closed out the season in style. This weather affected overall fiber quality and caused some cotton to fall to the ground.
2020 Panhandle Trials
AgriLife Extension collaborated with the North Plains Groundwater Conservation District to provide weekly video updates rotating between RACE trials during 2020. The video series, Cotton and Conservation, provided cotton producers real-time agronomic updates under the respective environmental and management systems.
In 2020, above-average spring temperatures resulted in early planting across much of the northern Texas Panhandle. However, above-average temperatures and below-average rainfall resulted in dry soils, and no trials were planted in the southwestern Texas Panhandle.
A June 9 windstorm affected cotton acres across the entire region resulting in blown-out fields or severe crop injury and delayed development. June and July temperatures ranged from 95 to 108 degrees Fahrenheit. Timely precipitation in July coincided with the bloom period across most northern Panhandle sites, but many rain storms were coupled with hail. Hot and dry conditions in August increased crop water demands.
In September, an early cold snap delivered temperatures below 4o F for 10-20 hours, depending on the location. A low of 34 F was reached at the Dallam County trial. This weather negatively affected micronaire development across the northern Panhandle. An early October ice storm was the final terminating event for regional cotton fields.
As a result of cumulative in-season stress, lint yield and grades were negatively affected at most northern Panhandle trials. Two locations were terminated because of hail injury.
According to the National Cotton Council, Texas growers intend to plant 6.4 million acres of cotton this season. Despite representing a 5.7% reduction in acreage compared to last year’s 6.8 million acres, this still is approximately 55% of the estimated 11.5 million cotton acres for the entire nation.
