9 Not-So-Secret Management Tips for High-Yield Soybean Growers
Management Tips for High-Yield Soybean Growers

What are high-yield soybean growers doing to take yields to lofty new heights? They’re adopting more-intensive management practices that enable them to consistently produce 80+ -bushel-per acre soybean. Most growers can implement these same practices to boost their soybean yield.

According to Dan Poston, DuPont Pioneer agronomy research manager in the southern U.S., there are 4 key factors that drive soybean yield. They are:

- Nutrients
- Sunlight (temperature)
- Water (including effective drainage)
- Effective Pest Management

Poston identifies 9 factors high-yield soybean growers tend to have in common and explains how they affect yields. Read about these factors.

On-Farm Key Learnings
On-Farm Key Learnings

To learn what growers are doing to obtain higher soybean yields, DuPont Pioneer conducted on-farm studies of intensive soybean management practices in the Western Corn Belt. Agronomists gathered data from 457 grower entries to learn which practices they have adopted are contributing most to higher per-acre soybean yields.

Among the issues that affect the ability to produce high soybean yields are:

  • Seeding Rates
  • Fertility and Crop Rotation
  • Foliar Fungicide-Insecticide Use
  • Harvest Timing

Learn which practices helped boost yields in these fields.

10 Crop Management Tips for Higher Yields

Get highlights from recent DuPont Pioneer agronomy studies that identify crop management practices that may help you increase soybean yields. Talk to your Pioneer sales professional and or visit the agronomy library for more information.

1. Variety Selection
Soybean variety selection is the first step in producing a high-yielding soybean crop. Each variety has specific strengths that can make it highly suited for a certain environment but less suited for another. Read more about selecting varieties.

2. Seeding Rate
As new varieties enter the market, the need to identify optimal seeding rates continues to be important. Higher seeding rates can offer advantages such as earlier canopy closure and lower weed competition; however, this may not always result in greater profitability. Continue with seeding rate.

3. Planting Date
DuPont Pioneer research has consistently shown the value of timely soybean planting. Recent research efforts have also looked at the effects of planting varieties of different maturities at normal and earlier timings. Learn more about planting dates.

4. Stand Establishment
Soybean seed treatment usage has increased as a way to help address concerns often associated with earlier planting dates. Other factors that put seedlings at a higher risk for poor emergence include no-till or reduced-till practices, cool and wet weather conditions, and heavy or compacted soils. View more on seed treatments.

5. Row Spacing
Numerous research studies over the past 40 years have evaluated soybean row spacing. In the last 10 years, studies show a 3 to 4 bu/acre yield advantage for soybeans planted in drilled narrow rows and 15-inch rows over 30-inch rows. Learn more about row spacing.

6. Soil Fertility
Despite their high demand for nitrogen (N), soybeans have historically received little or no N fertilizer. However, some studies have indicated that fixed N alone may not be sufficient to supply the N required to produce maximum yields. View more on soil fertility.

7. Disease Management
Soybean insecticide applications have increased in recent years throughout most of North America, mainly due to a rise in soybean aphids. Growers and researchers are exploring the benefits of insecticide use, particularly by including an insecticide with a fungicide application. Read more on disease management.

8. Insect Management
To better understand the potential yield benefits of insecticides applied with foliar fungicides, DuPont Pioneer conducted on-farm and small-plot research trials over multiple years and locations. Get trial highlights.

9. SCN Management
For effective soybean cyst nematode (SCN) control, a combination of strategies is needed, including planting SCN-resistant soybean varieties, rotating crops and using seed treatments with a component for SCN control. Learn more about SCN.

10. Weed Management
A critical part of managing weed resistance is controlling resistant populations before they get out of hand, which means being aware of potential resistance issues in the area and watching for weeds that have survived a herbicide application. Get weed management tips.

Kip Cullers Breaks World Record in Soybean Production

Kip Cullers

In 2010, Kip set a new world record soybean yield of 160.6 bushels per acre, six bushels higher than the world record he set in 2007. He achieved this with Pioneer® brand soybean variety 94Y71 (RR).

In 2006, Kip first set a world record by producing 139 bushels per acre with Pioneer® brand variety 94M80 (RR). He surpassed that mark the following year with the same Pioneer variety with a yield of 154.57 bushels per acre.

Kip operates a diversified farm southeast of Joplin, MO. He has been involved in farming for more than 20 years, owning or managing farms in Newton and Barry counties in Missouri.

  6. On your contest fields, what is your total fertilizer applied and when do you think it is best applied N-P K? We do a lot of strip-till in the fall, but because of wet weather last fall, we had some spring strip-till this year and it is probably my best looking field.
