Developing, Applying, and Evaluating Site-Specific Cotton Management Strategies in the Texas High Plains

Principal Investigator: Stephan J. Maas

Objectives:

  • Collect spatial field data (including soil samples, plant mapping, yield maps, soil electrical conductivity maps, topographic maps, and remote sensing imagery) from farmers' fields (Brightbill Farms and Brosch Farms) for analysis of potential management zones.
  • Set up experiments on these farms involving variable-rate seeding and defoliation, where portions of fields receive site-specific management (according to management zones delineated as per Objective #1) for comparison with other portions treated as controls.
  • Analyze statistically the results of these experiments to determine yield differences between precision agriculture and traditional practices, and to determine the economic differences between precision agriculture and traditional practices.

Development of Superior Fiber Quality and High Lint Yield Potential in West Texas Cotton Varieties

Principal Investigators: Dick L. Auld, Efrem Bechere, Eric Hequet, Mourad Krifa, Sukant Misra

Objective:

The overall objective of this research is to develop cotton varieties adapted to the Texas High Plains that produce high lint yield and superior fiber quality that demands a premium in the export market.

Specific Objectives:

  • Incorporate Roundup Flex cotton technology into elite cotton lines.
  • Inter-specific crosses to enhance lint yield and fiber quality.
  • Reduce the short fiber content of Texas Cotton using naked seed coat mutants.
  • Evaluate the fiber generated by the germplasm in this project for physical and chemical properties.
  • Determine market value (price and premiums/discounts) of fiber produced by elite lines and partially naked seed coat mutants.
