Two New ‘Focus on Cotton’ Presentations Provide Early-Season Fertilization, Weed Management Strategies for Boosting Yields

May 22nd, 2014

Memphis, TN --- A cotton grower’s actions early in the season can have a big impact on yields later on. This is especially true when it comes to early-season fertilizer and herbicide treatments.           

Two new ‘Focus on Cotton’ webcasts, published by Cotton Incorporated and the Plant Management Network, offer early-season strategies on fertility and weed management so growers can maximize yields when it’s time to harvest.

Fertilizing for High-Yield Cotton” by Glen Harris, Professor of Crop & Soil Sciences at the University of Georgia, gives growers, consultants, and other practitioners in the Southeastern U.S. a good understanding of basic fertilizer strategies for producing high-yield cotton.  It also covers the key fertility issues that can prevent growers from reaching their high yield goals.

Among many things, this webcast covers:

  • The essential nutrients in producing high-yield cotton
  • How N-P-K fertilizer recommendations are adjusted for yield goals
  • Which essential nutrients are mobile in soil
  • The importance of pH and how it affects soil nutrient availability
  • The difference between calcitic and dolomitic lime and why overliming may cause problems
  • The importance of potassium nutrition and foliar feeding
  • The use of unmanned aerial vehicles (UAVs) for increasing yield potential 

Palmer Amaranth: Biology, Ecology, and Management” by Peter Dotray,  Professor of Weed Science at Texas Tech University and Texas A&M Extension Specialist, will help consultants, growers, and other practitioners primarily in the Southwest region of the United States better understand the biology, ecology, and general management strategies to manage Palmer amaranth. This two-part talk specifically includes coverage of:

  • Palmer amaranth’s distribution and habitat
  • The influence of temperature on Palmer amaranth’s germination
  • The effects of Palmer amaranth density on cotton lint
  • Glyphosate resistant palmer amaranth management
  • Management in conventional tillage systems
  • Pre-emergent herbicide strategies 

By the end of this presentation, practitioners should know more about the growth and development of this troublesome weed and current management options that are available for effective weed management.

'Focus on Cotton’ contains nearly 20 webcasts on various aspects of cotton crop management. These talks, freely accessible 24 hours a day, 7 days a week, cover agronomic practices, crop protection, and ag engineering. The resource also features a new and improved Cotton Extension Search tool, where users can conveniently search for extension resources across all universities serving cotton producers.
