Corn seed manufacturers provided 74 hybrids that were part of the official variety trials on several LSU AgCenter research stations during 2014. Five variety trials were conducted at four AgCenter research stations on soils that included a Commerce silt loam and Sharkey clay at the AgCenter’s Northeast Research Station.

In addition to those research station tests, the on-farm core block trials were conducted with a total of 15 hybrids spread over 13 locations throughout the corn-growing areas of Louisiana. LSU AgCenter parish extension agents coordinated those activities.

The official corn variety trials were conducted according to LSU AgCenter best management practices. The on-farm core block trials were placed with active corn producers and subjected to the standard production practices for each producer. Several trials suffered from adverse growing conditions. Separate core block trials were conducted for “stacked” varieties – containing both glyphosate tolerance and insect resistance – and “nonstacked” varieties that had glyphosate tolerance only.

On-farm core block trial information is presented to provide yield results by trial, as well as some trend comparisons from compiled data. As opposed to the official variety trial research, core block trials sometimes are not replicated in the field, and rigorous statistical analyses often are not possible. Sufficient trials were conducted across a variety of locations, however, so meaningful and relevant observations can be made that will be useful to Louisiana producers as they make seed buying decisions.

The data provided in this publication should help you make more informed decisions about which varieties will work best for your production area.
