Soybean seed manufacturers participated in the Official Variety Trials (OVT) on LSU AgCenter research stations with 181 varieties and experimental lines. Seven OVT tests were conducted at research stations, which included a Commerce silt loam and Sharkey clay at the Northeast Research Station in St. Joseph, La. The on-farm core block trials were conducted at locations across the soybean-growing areas of Louisiana with parish agents coordinating trial activities. The soybean OVT trials were conducted according to LSU AgCenter best management practices. The on-farm core block trials were placed with active soybean producers and subjected to the standard production practices for that producer. Several trials suffered from adverse growing conditions.
Separate core block trials were conducted for different maturity varieties. The data are 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 are sometimes not replicated in the field, and rigorous statistical analyses are often not possible. However, sufficient trials were conducted across a variety of locations so 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 growers make a more informed decision about which varieties will work best for their production area.
