Soybeans and Agronomics


Soybean production is a high-value agricultural enterprise on Virginia farms and the Tidewater AREC serves as a key base for soybean production research and variety testing.  The goal is to research and develop cultural practices and identify varieties that enhance farm sustainability through increased productivity, production cost control, and reduction or elimination of environmental impact.  Agronomist, Dr. David Holshouser, leads this program along with collaborating scientists from campus, Tidewater and other ARECs, graduate students, cooperating growers, and technical staff with funding support from commodity board, industry, and other competitive grants.   In addition this research program is addressing problems with herbicide resistant weeds and double cropping systems.   Selected examples of current research topics include:

  • Official soybean variety trials at multiple locations throughout Virginia.
  • Controlling and preventing further spread of Palmer amaranth, a weed pest rapidly developing resistance to predominant herbicides used in crop production throughout the region.
  • Determination of optimal seeding rates for soybean production to reduce production costs and optimize grower profit potential.
  • Agronomic and economic comparisons of full-season soybean and double cropped small grain-soybean or sorghum systems in the mid-Atlantic region of the US.
  • Longer-term crop rotation systems for enhanced productivity of row crops in southeast Virginia.
