Ontario hybrid corn performance trials available online

December 11, 2014 - The 2014 Ontario Hybrid Corn Performance Trials Report is now available at

With yield data and production information from across the province, these trials are a valuable tool for farmers when selecting seed for the upcoming season.  The data reported on yield index, moisture, lodging and test weight provide farmers with information they need to choose hybrids suitable for their farms.

Produced by the Ontario Corn Committee, the report is available in an easy-to-download version that can be printed at home or it can be viewed online in a spreadsheet format that allows users to sort the list according to their interests.   

Also available are graphs that illustrate the performance of hybrids relative to the average for their maturity.

Corn hybrids were planted at 22 locations across the province in 2014.  Planting was delayed by wet weather at all locations.  The trials at Winchester (Table 2) and Ridgetown were discarded because of very uneven emergence.   The trial at Wingham was discarded because of excessive bird damage.   All other trials were harvested and are included in the report.  

Because of the cool growing season, moisture contents are higher than usual and test weights are lower than normal at most locations.  Very high winds in late November resulted in high levels of lodging at Exeter, Ilderton, Kerwood and Orangeville.  

The trials in Eastern Ontario were damaged by frost in late September.The Ontario Corn Committee will not be publishing a printed report.  If you are unable to access the trial results from the website, you may obtain a printed copy from the Grain Farmers of Ontario at 1-519-767-4138 or 1-800-265-0550.
