Finding High Yield Cotton for Producers

In 2002, only 22 percent of the cotton planted in South Carolina was high-yielding varieties. Clemson scientists are working to improve yields through field studies at the Pee Dee and Edisto Research and Education Centers, as well as on commercial farms.

Each year, some 30 studies evaluate cotton varieties, pesticide systems, plant growth regulators, and harvesting equipment and techniques. They also analyze agronomic practices, such as plant density, planting date, tillage systems and irrigation.

The research has helped to increase per acre cotton yield significantly by developing and identifying varieties that are more weed-and disease-resistant, hardier and more productive.

This information is needed to support the cotton industry, which generates more than $10 billion in revenue and 100,000 jobs in North and South Carolina.
