Background Information

Performance trials of commercial corn hybrids were conducted at six locations in Virginia in 2010. The Mt. Holly location consisted of both an irrigated and non-irrigated test. All locations were planted with a Wintersteiger PlotKing
2600. All locations were harvested with a Massey-Ferguson 8XP plot combine. The Blackstone site was abandoned due to drought stress. Yields have been adjusted to 15.5% moisture. Grain test weight, moisture, and plot grain weights were
measured with a GrainGauge® manufactured by HarvestMaster. A list of the companies participating in the trials is shown in the above table. All hybrids entered in the Virginia trials were those submitted by commercial companies. The locations at which particular hybrids were entered were specified by the company. Companies entering hybrids were charged a fee for each hybrid per location to support the Virginia Corn Hybrid and Management Trials.

This report contains the results for performance trials from commercial corn hybrids produced for silage at three locations in Virginia in 2009 as well as two and three year average performance, when available. In order to avoid problems with comparisons over sites and years, multi-year yields are presented as a percentage of the total at that particular site-year combination called relative yield. All locations were planted with a Wintersteiger PlotKing 2600 planter and harvested with commercial silage equipment. Yields are presented on a dry matter and 35% dry matter basis for comparison. All hybrids entered in the Virginia trials were submitted for testing by commercial companies or by Virginia Tech. The locations at which particular hybrids were entered were specified by the company. Companies entering hybrids were charged a fee for each hybrid per location to support the Corn Silage Performance Trials.

This report contains the results for performance trials from commercial corn hybrids produced for silage at
four locations in Virginia in 2010 as well as two and three year average performance, when available. In
order to avoid problems with comparisons over sites and years, multi-year yields are presented as a
percentage of the total at that particular site-year combination called relative yield. All locations except the
Washington County location were planted with a Wintersteiger PlotKing 2600 planter and harvested with
commercial silage equipment. Washington County was planted with an Almaco 2-row cone planter and
harvested with commercial silage equipment. Yields are presented on a dry matter and 35% dry matter
basis for comparison. All hybrids entered in the Virginia trials were submitted for testing by commercial
companies. The locations at which particular hybrids were entered were specified by the company.
