3 Ways Data Can Help Shape Hybrid Decisions

Making good seed decisions starts with leveraging the data that’s best suited for your operation. Ideally, this means fusing national data with highly localized data from your region or your farm specifically. Employ these three data-driven strategies to help ensure you are using the most relevant information when choosing your hybrids.


1. Consider your field environment and management style when making decisions for 2021.

Not all hybrids are created equal, and some respond better to certain management strategies than others. Response-to scores can help you match your seed choices to your management style, as well as to the potential of individual fields.  


WinField United has been collecting response-to data through our Answer Plot® program since 2011. Response-to scores measure the response of individual hybrids to population, nitrogen, rotation and fungicide. Using these scores lets you allocate your crop inputs budget more precisely and can lead to harvesting additional bushels.


For example, if you tend to pursue the high-yielding acre and use maximum inputs throughout the year, consider choosing seed with high response-to scores for the opportunity to achieve optimal yield potential through high management. Conversely, if you want to manage through the season using fewer inputs, choosing seed that responds favorably to fewer input applications is probably preferable to planting a hybrid with a high response to nitrogen or fungicide. Different seed products let you apply inputs less intensely but may still give you an ROI and yield potential that is acceptable to you, if you manage them as directed.


In 2019, we field-tested hybrids from CROPLAN®, DeKalb®, NK®, Mycogen® (now Brevant™) and Pioneer® for response to population (RTP), response to nitrogen (RTN), response to continuous corn (RTCC) and response to fungicide (RTF). The yield response ranges highlight the importance of understanding how the hybrids you choose react to different management practices to optimize yield potential

Response-to test Yield response range
Response to Population1 0.84 to 21.9 bushels per acre
Response to Nitrogen2 30.8 to 104.9 bushels per acre
Response to Continuous Corn3 5.8 to 36.7 bushels per acre
Response to Fungicide4 5.6 to 40.4 bushels per acre

Planting a hybrid with a high RTN score and managing with plenty of nitrogen, for example, added nearly 105 bushels per acre compared to planting the same hybrid under limited nitrogen conditions. Without proper crop management, those are bushels you may be leaving in the field.


Another hybrid selection tool is the WinField® United Characterization Charts (CHT Tool), which contains up to three years’ worth of Answer Plot seed data. This allows you to compare CROPLAN® hybrids against those from other major companies based on soil type, crop rotation, plant population and management practices. Even if you already know which hybrids you want to plant, be sure to leverage the CHT Tool to understand how to best manage those hybrids to derive optimal yield potential.


2. Demand data that proves performance.

It used to be common practice to try a few different hybrids throughout the season, discard the ones that didn’t work and then rely on those that did the following season. Because of evolving technology, that isn’t feasible anymore; hybrids don’t stay in the market as long as they used to. Moreover, just because a hybrid worked for you this year doesn’t necessarily mean it will work for you again next year. And just because a product didn’t work this year doesn’t necessarily mean you shouldn’t plant it again. This is where reliable data can help guide your selection process. Be sure your data is:

  • Validated by replication. The more data points you have, the stronger the data. Our Answer Plot data is backed by extensive replicated trials and run through a quality assurance process to help ensure greater accuracy.

  • Prescriptive, not descriptive. Graphs and spreadsheets about past performance have their place, but to be successful you need data-driven recommendations for your farm. Our data offers you a clear idea of what to do in the future.


You should know how to manage products from the very first year you plant them. Every new WinField United product (seed and otherwise) is tested in our Answer Plot system before going to market. So, the first year a product is in market, we have data available to help you determine if it’s a worthwhile investment for your operation.


3. Consult your agronomist to review this year and plan for next.

At the end of the season, you’ll probably have a significant amount of data collected. Reviewing that much information can be overwhelming, so team up with your agronomist to correctly dissect it. Together, you can review what happened this season and determine what needs to be changed for next season. Maybe it’s using a new hybrid that fits your needs better. Maybe it’s putting together a more realistic management plan. Bottom line, you and your agronomist want to know what went wrong, what went right and how to do better in the future. Your agronomist can help you view the season holistically, considering critical management and input elements and creating a plan that is rooted in data.


Although you never know what the season will bring, the highest odds of success come from managing the seed as recommended. For more information on the Answer Plot program, technology tools and how to get the most out of your seed investment, talk with your local trusted advisor.


1. National average yield difference between 30,000 and 37,500 plants per acre.
2. National average yield difference between non-limited and limited nitrogen applications; rates varied by soil type     and location.
3. National average yield difference between first-year and corn-on-corn rotations.
4. National average yield difference between fungicide application at R1 and untreated control.

Important: Before use always read and follow label instructions. Crop performance is dependent on several factors many of which are beyond the control of WinField United, including without limitation, soil type, pest pressures, agronomic practices, and weather conditions. Growers are encouraged to consider data from multiple locations, over multiple years, and be mindful of how such agronomic conditions could impact results.
