CORN SILAGE YIELD AND DIGESTIBILITY TRIAL

In the eighteenth year of our trial, we evaluated thirty-four seed varieties from eight seed companies on four Western New York farms. The host farms were Hi-Land Farms, LLC (Wyoming, long season varieties), True Farm (Perry, long season varieties), Breezyhill Dairy, LLC (Strykersville, short and mid season varieties), and Post Dairy Farms LLC (Oakfield, short and mid season varieties)

All of our test plot results for this and previous years are available in greater detail at our interactive test plot website which allows you to easily sort, filter, and graph the results of our variety test plots. It is available at

Two plots were located on each farm, one in well-drained soil and the other in marginally drained soil. The cooperator farm planted the corn; we harvested the crop. Two 17 foot 4 inch areas located at 60-foot intervals from each other were hand harvested and weighed for each variety. A subset of three plants from each harvested section (for a total of 6) was gathered and chopped using a chipper shredder. All samples were then vacuum packed and sent to Cumberland Valley Analytical Lab for 30-hour in-vitro analysis.

Tables A-C compare plant yield, dry matter, composition, fiber digestibility and the combined effect of these factors on milk production using the Milk 2006 index developed by the University of Wisconsin. NDF and starch are expressed as a percentage of total dry matter while NDF digestibility (DNDF) is listed as a percentage of total plant fiber. The varieties are sorted by day length.

Before deciding on a variety, take time to look at other silage trials. We also recommend reviewing your variety selection criteria with your nutritionist and crop consultant before making your final choices.

We would like to thank Dekalb, Doebler's PA Hybrids, Inc., Dyna-Gro, GrowmarkFS-InVISION, Hubner, Masters Choice, Mycogen Seeds, and Syngenta for their participation and financial support in the trial. A special thank you also to our cooperators: Greg and Ben Chamberlain; Brian, Brad, and Jeffrey True; Brad and Roger Almeter; and Dan and John Post for their time planting the plots and the use of their land.
