Hybrid choices: Yield consistency is key

Hybrid choices: Yield consistency is key

Corn farmers will soon start shopping for hybrids for the 2014 crop and according to Bob Nielsen, a Purdue Extension agronomist, the number one factor they need to consider is yield consistency. Each year, seed companies and land grant universities conduct a series of seed research trials to gauge the yield success of different hybrids in a variety of locations and conditions. The data can help growers determine which hybrids are likely to perform best in a number of scenarios.

"Documented consistency in yield performance is still the key to success in selecting hybrids that will perform well in your farming operation," Nielsen says. "When you are pressured to choose this hybrid or that one because the sales rep assures you it will perform well, don't hesitate to ask for the performance data that backs up the recommendation."

In years past, growers didn't need to lock in seed choices until January or February of the planting year, but recent competition has caused a need to make the decision in the fall. That scenario means neither seed company or university research trial data from the current year is available. But according to Nielsen, data from previous years will still give growers insight on most hybrids.

"Except for the newest hybrids, performance data from the previous year is useful for identifying consistent performers for your operation next year," he says. "Seek out summaries over many locations and avoid concentrating on single-site results."

Trials that evaluate hybrids in a variety of locations can assess yield performance under different types of weather patterns. This is important because, according to Nielsen, weather variability influences hybrid performance more than any other variable.

"If a hybrid performs consistently well over many sites, then it likely will perform well on your farm in the future," he says.
