Corn seed manufacturers participated in the LSU Ag-Center’s official variety trials with 68 hybrids during 2012.

The research station portions of the tests were conducted at two LSU AgCenter facilities – the Northeast Research Station and the Scott Research Center in Winnsboro. Soils involved at the stations were Commerce silt loam and Sharkey clay.

The on-farm core block trials were conducted with a total of 13 hybrids spread over 16 locations throughout the corn-growing areas of Louisiana, with LSU AgCenter parish agents coordinating trial activities.

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

The data 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, the on-farm core block trials sometimes are not replicated in the field, and rigorous statistical analyses often are not possible. Nevertheless, sufficient trials were conducted across a variety of locations that 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 a more informed decision about which varieties will work best for your production area.
