The University of Idaho is leading a multi-institution, federally funded research effort to harness artificial intelligence in the fight against one of agriculture’s most persistent yield problems — crop lodging, the tendency of cereal crop stalks to bend or collapse before harvest.
The National Science Foundation awarded the University of Idaho a four-year, $6 million EPSCoR grant to fund the development of advanced data collection technologies and AI models aimed at strengthening wheat, corn, and sorghum plants from the ground up. The award runs through 2030 and is fully federally funded.
For Latah County and the broader Palouse region, where wheat production anchors the local agricultural economy, the research carries direct significance. Stalk lodging — when grain stalks collapse before harvest machinery can collect them — costs farmers dearly every growing season, with global cereal crop losses from the problem estimated between 5 and 25 percent annually.
A Crop Problem with Global Consequences
The stakes are difficult to overstate. Wheat, corn, and rice together account for roughly two-thirds of all calories consumed by humans worldwide. Any meaningful reduction in annual losses from lodging would ripple through global food supply chains and commodity markets.
Daniel Robertson, an associate professor of mechanical engineering at U of I and the project’s lead investigator, framed the challenge in straightforward terms. “Two-thirds of the world’s calories come from wheat, corn and rice, all crops that suffer from stalk lodging,” Robertson said. He added that the issue is not purely a biological one: “This is fundamentally an engineering problem as much as a genetics problem.”
That dual framing — engineering and genetics working together — defines how the research team is structured. Three major research institutions are collaborating under U of I’s leadership, each tackling a distinct piece of the puzzle.
Three Universities, One Research Mission
The University of Idaho is spearheading the development of harvest-integrated sensing technologies — tools that can measure plant characteristics in the field with greater precision and efficiency than current methods allow. These sensors are designed to close what researchers call the genome-to-phenome bottleneck, a major obstacle in plant breeding where scientists can sequence plant DNA far faster than they can measure the physical traits that DNA produces.
AI researchers at the University of Nebraska Medical Center will take the data captured by those sensors and build machine-learning models capable of identifying genetic patterns linked to stalk strength. Meanwhile, Clemson University is focusing on the underlying genetics that govern how strong or vulnerable a plant’s stalk is in the first place.
Graduate students Tim Stevens and Isaac Looney are part of the U of I research team working under Robertson on the project.
The collaboration extends beyond research institutions. U of I is partnering with North Idaho College and Brigham Young University-Idaho to develop educational pathways connected to the work, offering students in Idaho a route into the growing field of agricultural technology and data science.
Building Tomorrow’s Crop Science Pipeline
The NSF’s EPSCoR program — Established Program to Stimulate Competitive Research — is specifically designed to build research capacity in states that have historically received fewer federal science dollars. Idaho’s inclusion as lead institution on a project of this size reflects the university’s growing strength in agricultural engineering and applied AI research.
For the Palouse wheat belt, the practical payoff could eventually come in the form of crop varieties better suited to withstand the weather and mechanical stresses of harvest. Breeding programs informed by AI-analyzed genomic data could dramatically shorten the time it takes to develop and release improved grain varieties to farmers.
The four-year timeline places the project’s conclusion in 2030, with findings expected to contribute to both the scientific literature and real-world plant breeding programs. The University of Idaho’s role at the center of this effort underscores the institution’s continued investment in research that serves Idaho’s agricultural heritage and the communities that depend on it.
