CORN GRAIN. Test zones, locations and maturities are: Companies participating in the 2000 hybrid corn grain trials.

Transcription

1 Test zones, locations and maturities are: Southern Zone: Lamberton, Waseca, and Plainview. Early Maturity Trial Relative Maturity (RM) and earlier. Late Maturity Trial and 115 RM. Central Zone: Morris and Rosemount. Early Maturity Trial - 95 RM and earlier. Late Maturity Trial and 105 RM. Northern Zone: Staples and Rothsay. Testing Procedure: Entries Each corn seed company could enter up to six hybrids per zone. Entries in each trial were based on the RM provided by the company. Because the University could also choose and enter hybrids in each test there may be more than six hybrids for a company in a test. Presentation of Data Yields in tables on pages that follow are given for individual locations along with yields and harvest moisture contents averaged across locations for Hybrids are ranked within a maturity group by moisture content averaged across locations for Least Significant Difference We show LSD values in tables that follow with a 0.2 alpha level, which means that when two hybrids differ in yield by the LSD value or more one can be 80% confident that the two hybrids differ in yield potential.
