Global Maize Project in the United States: Virginia

Four individual trials were conducted as part of the Global Maize study near New Kent, Virginia in the summer of 2015. The main study compared the mid-Atlantic farmer standard practices for corn production to a suite of practices identified as the “Ecological Intensification” (EI) treatment. Corn was planted into recently killed wooly pod vetch cover crop, which had been established in the fall by aerially seeding 25 lb/A into standing soybeans. An estimated 70% vetch stand was achieved.

The Global Maize project being conducted near New Kent, Virginia, is comprised of several experiments designed to compare the effect of various agronomic practices thought to increase corn productivity with standard farmer practices. One of the experiments has been evaluating the use of decision support systems (DSS) to optimize in-season N applications.

A study was conducted near New Kent, Virginia in the summer of 2013 to compare the effect of various practices thought to increase corn productivity over standard farmer practice (FP). The trial was planted on April 24 with the corn hybrid Dekalb 65-19 used in the Ecological Intensification (EI) treatment and Pioneer Brand 1319HR used in the FP treatment. Changes in practices in the EI treatment from FP included: seeding rate was increased by 18.
