Summary

​Nutrient management in cotton is critical to maximizing lint yields and quality as well as it represents a large portion of the total expense in cotton production. Petiole and tissue testing allows producers and crop consultants to make inferences about the overall nutrient management program in-season and also allows for the identification and correction of nutrient deficiencies. The presentation will identify sufficiency ranges for the primary and secondary nutrients in cotton during the bloom period and how these ranges correlate to lint yield. For example the presentation contains critical leaf nitrogen and petiole nitrate-N thresholds based on current research using contemporary varieties. Producers can utilize tissue and petiole testing to predict yield at intervals during the growing season to fine tune their nutrient management program.

About the Presenter

Hunter Frame​ Hunter Frame attained his Bachelor of science degree in Crop and Soil Environmental Sciences from Virginia Tech in 2007. He then attended the University of Tennessee for his Masters of science where his research focused on nitrogen management in burley tobacco production. Upon graduating from Tennessee in May 2009, Dr. Frame returned to Virginia Tech to pursue his doctorate in soil fertility and nutrient management. His PhD research focused on ammonia volatilization from urea based nitrogen fertilizers in corn and winter wheat production systems. Upon completion of his doctorate in 2012, Dr. Frame accepted the position of Field Crops Agronomist at the Tidewater Agricultural Research and Extension center in Suffolk, VA. Dr. Frame’s research program focuses on nutrient management, cultural practices, and variety testing in Virginia cotton production.​
