The purpose of this study is to compare the use of different sugar products, applied at the V4 growth stage, and their impact on yield and profitability.

A recent surge of interest in sugar applications has resulted in multiple new PFR sugar studies. Last year, we saw fairly consistent returns with in-furrow sugar applications that theoretically fed the microbial activity in the soil. This year, we tested four different products, both in-furrow and foliar-applied. Three of these products have additional components such as biological compounds, humic or fulvic acids, and one has a small dose of molybdenum.

Although our foliar applications at other locations have provided mixed results, all the products tested provided a positive yield response and an increased return on investment. The increased response at this location could be a result of the increased stress this crop endured.
