Unlocking the Future of Crop Yields: Insights from Leading Experts

At the Successful Farming Main Stage during Commodity Classic, a panel of researchers and award-winning farmers unravelled a critical question for the 2026 agricultural season: Where will the next bushels come from?

The discussion featured University of Illinois crop physiologist Fred Below, National Corn Growers Association (NCGA) yield contest champions Troy Uphoff from Illinois and Casey Hook of Arkansas, along with independent agronomist Jim Isermann. Their consensus was clear: there isn’t a magic bullet for achieving higher yields.

Instead, they emphasized the synergistic relationship between genetics, fertility, environment, and management practices to drive crop productivity.

Start With The Fundamentals

Below, with decades of expertise, highlighted critical factors affecting corn yield through his widely recognized frameworks: the Seven Wonders of the Corn Yield World and The Six Secrets of Soybean Success.

“These management factors are profoundly impactful on corn yield every year,” Below noted, offering them as essential tools for farmers and agronomists.

Key Factors: They include hybrid selection, fertility, crop rotation, plant population, and effective residue management for corn, while soybeans mirror similar drivers like genetics and climate influence.

“The magic lies in how these factors interconnect,” Below added, pointing out the opportunities and challenges they present.

Fertility Sets the Foundation

For Uphoff, fertility lays the groundwork for yield potential throughout the season.

“Fertility is paramount; it’s akin to starting your day off right,” he explained, illustrating a comprehensive nitrogen management strategy beyond a single application.

This strategy encompasses fall applications, spring doses, and sidedress techniques aimed at ensuring nitrogen availability during critical growth phases. “We aim to eliminate bad days for the plants,” Uphoff clarified.

Below reiterated nitrogen’s crucial role in yield formation. A 300-bushel corn crop requires over 330 pounds of nitrogen for optimal growth, amounting to about 1.12 pounds of nitrogen per bushel.

Yield Contests Drive Experimentation

While yield contests showcase impressive numbers, panelists stressed their greatest value lies in the learning journey they facilitate.

“Competing has driven me to not just achieve high yields but also understand their causes,” Hook remarked, emphasizing the importance of grasping the underlying factors for replicability.

Contest plots provide fertile ground for testing innovative ideas and identifying inputs that do not yield returns.

On-farm Trials Bridge The Gap

Isermann collaborates with farmers conducting on-farm trials, establishing a vital link between academic research and real-world application.

“While there’s a wealth of research available, these trials help connect it with what farmers implement,” he explained.

Advancements in precision agriculture enable growers to easily perform valid comparisons across their fields. “Precision technology and geospatial software present immense opportunities,” Isermann noted, emphasizing careful planning and accurate recordkeeping for reliable outcomes.

Efficiency Becomes a Bigger Focus

The conversation also shifted toward enhancing efficiency, particularly with nitrogen usage.

Isermann highlighted the NCGA’s Class J category, capping nitrogen use at 180 pounds per acre, to promote environmental stewardship and economic accountability.

Early Decisions Matter Most

Key decisions impacting yields are often made well before midseason. According to Hook, the initial 72 hours post-planting can be crucial for soybeans.

“Keeping soil temperature below 70 degrees during this period increases success odds,” he revealed.

Where The Next Bushels May Come From

As the panel looked ahead, they identified several avenues likely to enhance yield gains.

Better fertilizer placement, such as strip-till and targeted micronutrient applications, emerged as crucial tools. Moreover, narrower row spacing may maximize sunlight exposure and support denser plant populations.

Uphoff pointed out root system development and row spacing as critical components. “Our goal is to transition to 20-inch row corn,” he stated.

Hook emphasized the significance of bolstering soil microbial health. “Increasing carbon and sugar production in the soil signifies long-term improvements,” he noted.

AI technology may also play a crucial role in processing the extensive data generated on farms, a sentiment shared by Below who warned of the challenges in interpreting this data efficiently.

Bringing It All Together

Farmers aspiring for elevated yields should recognize that advancements seldom arise from a single innovative practice. Instead, continuous refinement, experimentation, and the adaptability of farming systems are essential.

Uphoff concluded with a powerful reminder: “What works on my farm or Casey’s may not work on yours. That’s why harnessing data is so vital.”
