UGA Cotton On Farm Variety Trials Results 2025

Table titled “2025 On-Farm Cotton Variety Trial Results – FINAL” showing lint yield per acre for 10 cotton varieties evaluated across multiple Georgia counties under dryland (DRY) and irrigated (IRR) conditions. Columns list counties and production system type, with lint yields reported in pounds per acre for each variety. An “All Location Average,” LSD (P=0.1), and percentage above trial average are included. The overall trial average is 1,324 lbs per acre. Cells shaded green indicate yields above the location average. Notes at the bottom define DRY as dryland, IRR as irrigated, bolded varieties as top-yielding group, and indicate that NG 4611 B3XF was tested as AMX 12677 B3XF.

Two tables summarizing 2025 On-Farm Cotton Variety Trial Results divided by location performance relative to the overall trial average of 1,324 lbs lint per acre.

The top table is titled “Locations that yielded BELOW the trial average (1,324 lbs/acre)” and reports lint yield per acre for 10 cotton varieties across dryland and irrigated counties including Mitchell, Turner, Burke, Appling, Cook, Effingham, Worth, Lowndes, and Dooly. Columns include All Location Average, LSD (P=0.1), and percent above trial average.

The bottom table is titled “Locations that yielded ABOVE the trial average (1,324 lbs/acre)” and reports lint yield per acre for the same varieties across counties including Dodge, Mitchell, Colquitt, Oconee, Burke, Grady, Pulaski, Bulloch, Seminole, Sumter, Tattnall, Coffee, Houston, Bleckley, and Miller under dryland and irrigated conditions.

Lint yields are displayed in pounds per acre, with green-shaded cells indicating yields above the location average.

Cotton growers across southeast Georgia experienced a variable production season in 2025. As input costs remain high and weather conditions continue to fluctuate, variety selection plays a critical role in managing risk and maximizing yield potential.

To provide locally generated data, UGA Extension conducted a multi-county on-farm cotton variety trial across both dryland and irrigated production systems. The trial included multiple commercially available varieties evaluated across 20 locations, with lint yield reported in pounds per acre.

Overall Trial Performance

The overall trial average across all locations was 1,324 pounds of lint per acre. Yield performance varied depending on environmental conditions and management systems. Differences observed among locations emphasize the importance of evaluating variety performance across multiple environments before making planting decisions.

While some entries performed above the overall trial average, others were closer to or below average depending on location. These results reinforce that variety selection should be based on consistent performance across environments rather than performance at a single site.

Influence of Location

Environmental conditions had a significant impact on yield outcomes in 2025.

Locations below the overall trial average ranged from 824 to 1,365 pounds of lint per acre. These sites were primarily dryland environments where rainfall distribution and seasonal stress influenced production.

Locations exceeding the overall trial average ranged from 1,343 to 1,737 pounds per acre, with some individual yields exceeding 1,800 pounds per acre under favorable conditions. These results demonstrate the yield potential achievable when environmental conditions and management align.

Considerations for 2026 Variety Selection

Results from this trial highlight several important considerations for producers:

• Evaluate multi-location data when comparing varieties
• Consider performance stability across dryland and irrigated systems
• Review trait packages, disease tolerance, and agronomic fit
• Use multi-year data whenever possible to reduce risk

On-farm trials provide valuable insight into how commercially available varieties perform under real-world Georgia growing conditions. For assistance interpreting these results or for additional production recommendations, contact your local UGA Extension office.
