Precision Planting

Description

Climate change trends and simple year-to-year variability in weather often pushes the limits of crop insurance coverage for early (April 26) and late planting (June 10 with reduced coverage until July 5). Risk Management Agency (RMA) does review planting dates for insurance coverage and data from long-term planting date studies have been used to make revisions. As a result, it is important to initiate a long-term plant of date study for soybeans to assess the yield response curve and appropriate reductions in insurance coverage.

Location:
Volga 44.321944, -96.924444

Treatments:
• Four planting dates: May 17, and two weekly intervals thereafter.
• Two seed treatments (with and without fungicide),
• Two soybean variety two maturities (1.4 and 2.4)
• Four seeding rates (100K, 135K, 170K, and 205K) using 30 inch row spacing.

Expected outcomes/Significance to Growers:
Data will be used to update the soybean best management practices manual.

This project is a collaborative effort of SDSU Research, SDSU Extension, South Dakota Agricultural Experiment Station, and the South Dakota Soybean Research and Promotion Council.
