The official list of corn hybrids recommended by the LSU AgCenter for production in 2004 is out and will be posted on the Internet soon. This year, we had 87 entries, the largest number entered into the trials thus far. As expected, most of the hybrids that did well in the corn demonstrations across the state are included in the recommended list.
For the recommended hybrid list, there are two categories regarding days to maturity: early at 100 to 110 days and medium at 111 to 120 days. There is usually a full-season category, which is 121 days or more, but no hybrids that were recommended fell in that category this year.
The list below includes all recommended hybrids (not differentiated by recommendation per location) with their respective two-year mean over locations, including the 2002 and 2003 growing years.
In addition to the recommended hybrid list below (two-year mean over locations with yields in bushels per acre), I have added a few comments on select hybrids that stood out in demonstrations as well as in the variety trials across the Louisiana.
Early maturity: Pioneer 34B23, 139 (bushels per acre); N65-M7, 140.
