- To determine if various agronomic inputs could reduce the impact of environmental, weed, disease, and insect stresses in soybean.
Research Site Details
- Two soybean products, a 2.8 and 3.7 relative maturity, were used and planted in a 30-inch twin-row configuration.
- Treatments included:
- RI: Rhizobium inoculant alone (Optimize®)
- FF: Foliar fungicide alone (Delaro® 325 SC fungicide) applied at growth stage R3
- RI + FF: Rhizobium inoculant + foliar fungicide at R3
- FI: Foliar insecticide alone (Warrior®) at R3
- RI + FI: Rhizobium inoculant + foliar insecticide at R3
- FI + FF: Foliar insecticide at R3 + foliar fungicide at R3
- RI + FI + FF: Rhizobium inoculant + foliar insecticide at R3 + foliar fungicide at R3
- UTC: Untreated control
Understanding the Results
- The combination of all three inputs, rhizobium inoculant, insecticide, and fungicide (RI + FI + FF), as well as the insecticide and fungicide combination (FI + FF) provided the highest average yield for both soybean products.
What Does This Mean for Your Farm?
- Achieving maximum soybean yield potential depends on management practices that minimize plant stress and reduce the impact of environmental conditions on plant health.
- Reduction of stresses with the use of fertilizer, inoculant, fungicide, and insecticide can help achieve maximum yield potential.
- Agronomic practices, such as row spacing, proper planting date, and population, can help reduce the impact of environmental stresses.
