3 Minute Read Time | Huxley, Iowa Field Research
Throughout the state in any given year, our products are put to the test in various research trials. These trials allow us to gain insights to help complete a year-long story of product performance, agronomic characteristics, and weather patterns.
We spend months planning out our research programs across the region, but as you know, our research is just as vulnerable to extreme weather conditions as the crops on your farm. 2019 was delayed planting due to wet conditions. 2020 a global pandemic didn’t slow our essential crop production industry, however an August derecho can ruin months of work and resources in about 15 minutes. What will 2021 bring? With conditions like this, we often see research results that may not match data from prior years, but we can use these challenges as an opportunity to evaluate, learn, and provide better insights for the future.
We hope you enjoy all of this information and find it insightful.

Soybean Research
What pairs nicely with early planting dates?
A switch to earlier soybean maturities influences planting, harvest, and pod fill dates.
This third year of Iowa research evaluates the trend towards early soybean maturities. Comparing early and normal relative maturities in sets of soybeans from the north and south, this report shows the difference September rainfall can make on pod fill.
Determine if relative maturity shifts are right for soybean fields at nearby Iowa locations by reviewing yield data from 2018 to 2020.
Soybeans programmed to handle the most stressful situations.
Fungicide inputs and relative maturity adjustment are combined for top performing soybeans.
Huxley research explains how fungicide applications support early and late-planted soybeans, and where profitability falls with average yield benefits. Relative maturity is brought to the discussion as full-season soybean varieties performed greater than early products.
Find how shifting soybean maturities supports different planting dates and fungicides reduced plant stress regardless of the planting season.
Looking for a positive soybean experience?
Reduce plant stress with fungicide application and seeding rate management.
Fungicides are often used to reduce soybean stress caused by disease. At Huxley Learning Center soybean stress tolerance was measured as yield differences from 18 soybean varieties. Plant response to fungicide is individual to soybean variety and seeding rates. Optimism with soybean inputs and management leads to a positive profit.
Robust research demonstrates profitability from soybean inputs: seeding rate, variety, and fungicide application.
60 days of Japanese beetle feeding – start the window of control early.
Insecticide shouldn’t wait for R3 fungicide applications when there is high Japanese beetle pressure.
Four different soybean varieties were treated with Leverage® 360 insecticide in this application timing trial. Foliar feeding from Japanese beetles begins mid-June and can continue through mid-August. Huxley researchers determined earlier insecticide applications would offer a yield advantage compared to waiting for a combined fungicide and insecticide application.
Japanese beetle populations are sporadic, but when scouting determines heavy feeding is occurring, insecticide applications should be early, not late.
Deluxe soybean treatment – but hold the nitrogen!
Managing soybeans as intensely as corn for maximum yield potential.
Nine different treatments included different input combinations for soybean production at Huxley, IA. Seed treatments, seeding rate, nutrients, fungicides, and insecticides are investigated with yield and profitability playing out in a variety of ups and downs. Find which inputs you can pass on as standard soybean treatments are built upon to increase production.
Return on investment tends to increase with soybean inputs.
Historical tillage and current soil structure roles in soybean production.
Tillage affects soil structure, see how soybeans react as the environment below them changes.
Keep up to date with current soybean products and new tillage implements as Huxley researchers explore interactions of these over three years (2019 to 2020). Soil changes take time and crop response to tillage is site-specific. Additional years of data are needed as tillage, drainage, weather, and cropping systems affect the soil structure dynamic.
Soybean fields can be updated with new tillage equipment or no tillage at all if soils and crops respond well to no-till.

Corn Research
The ear differences are visible- when you change this input.
Put fertilizer money where your corn is.
Three nitrogen rates (low, medium, and high) were used on fourteen DEKALB® Brand Blend corn products with this trial in Huxley, Iowa. Yield potential and profitability with different nitrogen rates are discussed. Check out photos of the side-by-side ear comparisons for each DEKALB® Brand Blend corn product.
This study shows all 14 corn products were profitable at the Atlantic, Iowa location.
A lot of combinations but which is the right one for you?
Get the most out of your ground with the corn choices you make as planting season approaches.
The Huxley Learning Center combines 48 corn products in 2020 and 45 corn products in 2019 with several seeding rates and row spacing combinations for a dynamic look at product placement.
Researchers are finding answers on inter- and intra-row spacing for corn plants. Row spacing is often locked in with equipment availability; however, seeding rate can be tailored for individual corn products.

The goal at the Bayer Crop Science Huxley Learning Center is to provide you with up-to-date, relevant agronomic information that will benefit you and your operation. With that goal in mind, this booklet contains the 2019 harvest research summaries from a number of our key trials and demonstrations around corn and soybean management systems for Asgrow and DEKALB customers.
