North Carolina’s soybean farmers have the opportunity to buy several different products to put on their seed prior to planting, or in the furrow with the seed at planting. To test whether some of these products are likely to produce a profitable yield increase, replicated on-farm tests were conducted in Greene, Hyde, and Johnston counties in 2016.
Several of the products produced a yield increase of 1-2 Bu/A, which may or may not be profitable, depending on the cost of applying the product. The fungicide Rancona improved yields by 1.2 Bu/A when applied to the seed. The enhanced inoculant Optimize improved yields by 1.4 Bu/A, while the fertilizer BioForge improved yields by 1.7 Bu/A when applied to the seed. Agzyme applied in the furrow with the seed improved yields by 1.0 Bu/A, while the fungicide
Priaxor applied in the furrow improved yields by 1.6 Bu/A. Three other products tested did not improve yields.
