Corn seed manufacturers participated in the Official Variety Trials (OVT) on LSU AgCenter Research Stations with 88 varieties. OVT tests were conducted at 4 sites: On a Commerce silt loam and Sharkey clay at the Northeast Research Station, The Dean Lee Research Station near Alexandria and at the Scott Research Station in Winnsboro. The on-farm core block trials were conducted with a total of 21 varieties over 28 trials throughout the corn growing areas of Louisiana, with Parish Agents coordinating trial activities. The corn core block trials were placed with active corn growers and subjected to the standard production practices for that grower. A few incidents occurred that resulted in the loss of a few data points, and some trials suffered from adverse growing conditions. Given that, most trial averages were consistent with historical yield averages for the state.

In the case of the core block trials, separate trials were conducted for ‘stacked’ varieties - that had both glyphosate resistance and insect resistance – and ‘non-stacked’ varieties that had glyphosate resistance only. In 11 cases, stacked and non-stacked trials were conducted in the same field, and some comparisons are made. The data are presented to provide yield results by trial, as well as some trend comparisons from compiled data. As opposed to the OVT research, core block trials are often not replicated in the field, and rigorous statistical analyses are often not possible. However, enough trials were conducted across a variety of locations that meaningful and relevant observations can be made that will be useful to Louisiana growers 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.
