Brief Project Summary:

Periodically, new products or new uses of existing products, appear on the market for soybeans and receive enough favorable publicity to generate questions from producers and suppliers about their potential profitability. It is usually difficult to answer these questions confidently and accurately, without reliable in-state test results. This extension project incorporates findings from replicated on-farm tests of new or unique foliar products that may increase soybean yields and profits. Trials seek to improve the farm level profitability of producing soybeans in North Carolina, investigate potential of these products, train county extension personnel and support NCSU’s Soybean Extension On-Farm Test and Demonstration program.

Key Benefactors:
farmers, agronomists, extension agents

Information And Results
Final Project Results

Foliar fungicides sometimes led to statistically significant soybean yield increases. Double-MOA fungicides were more effective at increasing soybean yield on average than single-MOA fungicides. Sugar applications did not increase soybean yield. Foliar fertilizer use sometimes resulted in a statically significant soybean yield increase, depending on growth stage when applied. There are cases where micronutrient deficiencies justify the use of a foliar fertilizer application and positive yield responses can be observed in these situations.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
