On-Farm Research Results: Impact of Torque ST on Corn Yield March 7, 2018
This report synthesizes the results of seven Torque™ ST studies in Nebraska between 2010 and 2015. According to product information published by Monsanto BioAg, Torque ST is a seed-applied growth promoter designed to improve soil microbial activity and enhance nutrient availability.

The product was applied at a rate of 8 oz/acre in all studies except the two Saunders County studies, where it was applied at a rate of 16 oz/acre. Site-specific data is included in Table 1. Most studies reported data for yield and grain moisture; this data is presented in Table 2. Torque ST's active ingredient of 2 x 10-7 percent lipo-chiooligosaccharide (LCO) is formulated for corn applications in an aqueous carrier accounting for more than 99% of the product.

|* Number of replications is not available for all sites, however Nebraska On-Farm Research Network standards require a minimum of three replications for inclusion.
† All data except for the 2010 data is corrected to 15.5% moisture.
A Indicates that Torque ST was applied at a rate of 16 oz/acre at the site. At all other sites, Torque ST was applied at 8 oz/acre.
Indicates yield is significantly lower for the Torque ST treatment at alpha = 0.1.
Indicates yield is significantly higher for the Torque ST treatment at alpha = 0.1.
SummaryIn one of seven studies applying Torque ST resulted in a 17 bu/acre yield increase. At another site, Torque ST resulted in a 4 bu/acre yield decrease. The remaining five sites saw no statistical yield difference for using Torque ST.
