Program Focus

I strive to improve agronomic production systems via the discovery, integration, and implementation of better crop and soil management practices that benefit agriculture and our society at large. My focus is on intensively managed soybean cropping systems, cover crops, and pest management issues.  I conduct the official soybean variety test in five regions throughout the Commonwealth and serve as educational adviser for the Virginia Soybean Association and Virginia Soybean Board.

Role of Graduate Students

Graduate students will take an active role in developing and implementing all goals and objectives of their research project.  Students are expected to spend their summers at the Tidewater AREC in Suffolk, VA, where they will conduct the majority of their research.  They will provide assistance for additional research conducted by their major professor and others at the Tidewater AREC.  Student’s research will be presented at regional and/or national meetings and they will be expected to participate in extension programming efforts.

Future Research

  • Agronomic and Economic Comparisons of Small Grain and Soybean Cropping Systems
  • Appropriate Seeding Rates for Double-Cropped Soybean Planted After Barley
  • Physiology of Soybean Yield and Variety Advancement in Virginia Cropping Systems
  • Foliar Soybean Disease Incidence, Severity, and Interaction with Agronomic Factors
  • Improved Cover Crop Systems for Virginia
  • Increasing Early-Season Growth and Yield in Double-Cropped Soybean

Additional detail on each of the above projects may be found at the Tidewater AREC Soybean Extension and Research website: http://www.arec.vaes.vt.edu/tidewater/soybean/. 

Extension Program

Extension Philosophy

I extend agronomic knowledge and understanding by: 1) observing current practices and listening to concerns; 2) improving the meaning and application of and simplifying scientific principles and research; and 3) guiding the implementation of improved production practices through education and demonstration so to change behavior that leads to profitable and environmentally responsible agriculture.
