The purpose of this study is to evaluate three different biologicals at a V5 growth stage foliar application. These products were evaluated for their effects on plant health, yield and profitability.

These treatments were applied at the V5 growth stage, which is the key timeframe when kernel rows are determined. A rainfall event occurred two days following the foliar application, which likely promoted the uptake of these foliar products. The goal with these products is to mitigate stress on the plant. At the V12 growth stage, height differences were observed in the different treatments, with the control having the largest plants. Although the plants were slightly smaller where the foliar applications were made, this did not directly correlate into more yield.
