The purpose of this study is to evaluate various starter additive products, applied in-furrow, and their effects on yield and profitability.

2017 Kentucky Corn Starter Additive Study - In-Furrow

In our early-season observations, we noted that the application of in-furrow starter additives did not help with emergence. However, in the faster emerging hybrid (BECK 6076SXbrand) a greater Net Effective Plant Stand (NEPS) was present where a starter additive was applied. This indicates that the faster emerging hybrid came up more quickly and was better able to utilize the nutrients and microbes that were added at planting. More specifically, higher microbes in the soil helped with early-season nutrient uptake as the products containing the greatest amounts of microbes, NanoZyme 2.0 and Environoc® 401, showed the greatest yield increases.
