Summary

​This presentation helps the viewer maximize water use efficiency (WUE) in cotton, an inherently drought-tolerant plant. In this talk, the author offers an overview of water management in cotton, as well as specific management recommendations for increasing water use efficiency through the use of cover crops, sensors, and variety selection.

About the Presenter

Tyson B. RaperTyson B. Raper is the Cotton and Small Grains Specialist for the University of Tennessee. Dr. Raper attended Auburn University for his bachelor’s degree in Agricultural Business and Economics with a Minor in Agronomy and Soils. He later completed his master’s degree with Dr. Jac J. Varco at Mississippi State University studying the potential to remotely detect nitrogen deficiencies in cotton. Dr. Ra​per completed his doctor of philosophy with Dr. Derrick M. Oosterhuis at the University of Arkansas examining the impact of potassium deficiencies on remotely detecting nitrogen deficiencies in cotton and development of a drought stress index from temporally dense, spatially sparse soil moisture measurements. Currently, Dr. Raper’s research program focuses on increasing fertilizer use efficiencies through alternate placements, the remote detection and amelioration of nutrient stresses, and use of soil moisture to quantify experienced drought stress in variety trials.
