Terry Aukes says leveling out his yield potential risks is a no-brainer with planting blended soybean seed varieties. He’s seen the strategy work just as well in the heavily manured areas of northwest Iowa and Minnesota as it does in the prairie pothole, wet, disease-prone areas of South Dakota. "You can't have a one size (variety) fits all mentality and get the most out of the soybean varieties you choose," he says. "Meet in the middle."
This example Pioneer IMPACT trial plot of 40 to 50 similar maturity varieties tests consistently on a range of environments in an area, testing close maturity groups together. Each plot makes 40-50 variety comparisons across various environments. Yield differential can be sizeable within maturities.
Six secrets of soybean success
Fred Below, University of Illinois crop physiologist, identifies the following six management strategies as key to soybean success:
- Use crop management to mitigate the negative impacts of weather-induced variations in soybean yields that you cannot control.
- Improve soil fertility through balanced crop nutrition and fertilizer placement technologies.
- Maximize genetic yield potential by selecting varieties that respond to increased management.
- Protect yield potential and maximize seed fill by using foliar fungicides and insecticides.
- Enhance seed emergence and vigor through the use of fungicidal, insecticidal and plant growth regulator seed treatments.
- Use narrow row spacing for maximum light interception and optimized fertilizer placement strategies in corn-soybean rotations.
