Virginia Tech 2010 Growing Season Soybean Variety Trials

Professor & Extension Agronomist at Virginia Tech, reminds us that the results are expressed as relative yield - not actual yield, but rather a percentage of how well a particular variety yielded relative to all other varieties at a particular location. For instance, an average relative yield of 105 means that variety yielded an average of 5% more than the other varieties tested.

Effectiveness of Seed Treatments for Yield Enhancement

From the 2007 growing season

The variety ‘Southern States RT 3851N was planted between April 20 and May 4 on 15-inch centers in replicated strip plots in four locations: Middletown, Smyrna, Georgetown and Selbyville. The following treatments were evaluated and compared to an untreated control: Apron Maxx RTA, Cruiser 5FS, and Cruiser Maxx (combination of Apron Maxx and Cruiser 5FS). Stand counts and insect data were collected in all four locations. Yield data was taken at the plots in Selbyville, Smyrna and Middletown at or shortly after physiological maturity.

At all four locations, no significant differences were detected between the untreated control and the seed applied treatments for stand count. For the locations where yield was taken, this same trend occurred for the yield component. Non-significant yield differences between the untreated control and the treated plots ranged from zero to two bushels per acre depending on location. The Cruiser treatments did provide significantly better bean leaf beetle control with respect to fewer undamaged plants compared to the untreated check and fungicide alone treatment although this difference did not translate into a yield advantage for Cruiser seed treated plots. However since bean pod mottle virus was identified for the first time in Delaware in 2007, early season bean leaf beetle management may become more important in the future. Data from the Mid-West indicates that the use of seed treatments may be one part of an overall effective pest management program.
