The 11-year mean for soybean yields at the TSM® Research Farm continues to show TSM® E as the high-yielding treatment.  TSM® E averaged 62 bu./acre over the past 11 years, with TSM® A and the Tri-State recommendations coming in second at 60 bu./acre.  The U of IL treatment averaged the least with 57 bu./acre.  While 57 bu./acre is still a good soybean yield, with the high price of soybeans these days a 5-bu./acre difference from what the TSM® E treatment produced is a substantial loss in revenue.
