Decomposition of Litter and Root Residues From Perennial Intermediate Wheatgrass Governed by the Soil Microbiome and Different Earthworm Species

Journal of Sustainable Agriculture and Environment
Introduction Perennial intermediate wheatgrass (IWG, Kernza®) establishes an extensive root system which positively impacts nutrient retention and biodiversity and therefore offers a regenerative alternative to current annual wheat production.

Reductions in soil water nitrate beneath a perennial grain crop compared to an annual crop rotation on sandy soil

Frontiers in Sustainable Food Systems, 2022
Nitrate (NO3--N) leaching into groundwater as a result of high nitrogen (N) fertilizer rates to annual crops presents human health risks and high costs associated with water treatment.

Kernza in Wyoming: Perennial Grains for Vulnerable Lands

Agronomy
Kernza®, a perennial grain crop created from intermediate wheatgrass (Thinopyrum intermedium), has the potential to mitigate soil degradation in semiarid croplands of the Northern High Plains.

Coating Kernza^® Seeds with Hydrophilic Polymers and Mycorrhizal Inoculants Affects Seedling Emergence and Growth in Drought

Agronomy
Perennial grains, such as Kernza® (Thinopyrum intermedium) show promise in their ability to produce grain crops while withstanding drought and temperature extremes. However, Kernza establishes slowly, particularly in dry soils.

Different scenarios in land suitability assessment for Kernza®-intermediate wheatgrass (Thinopyrum Intermedium), a novel perennial grain crop for Argentina

Revista de la Facultad de Ciencias Agrarias
Land degradation, climate change, soil and water contamination have led to increased interest in sustainable agricultural practices. Most agricultural practices are focused on growing annual crops, which require significant amounts of synthetic ...

Mechanisms of soil organic matter formation for perennial grain Kernza® under contrasting nitrogen management

Frontiers in Soil Science
Restoring soil organic matter (SOM) in arable land is considered one of the best natural solutions to sustain food production and mitigate climate change. With typically deep, robust root systems compared to annual grains, perennial systems are likely to

Practical recommendations for researchers engaging in on‐farm research

Agronomy Journal, Volume 118, Issue 4, July/August 2026.
Abstract Though on‐farm research is crucial for addressing agricultural needs, it presents challenges that can derail projects if not addressed. Unlike small plot or greenhouse studies, on‐farm research evaluates tradeoffs in real‐world systems, offers access to diverse environments, and relies on farmer–researcher collaboration.

Evaluation of disease resistance in intermediate wheatgrass and genome‐wide association for fusarium head blight‐related traits

Crop Science, Volume 66, Issue 4, July/August 2026.
Abstract Intermediate wheatgrass (IWG) [Thinopyrum intermedium (Host) Barkworth & D. R. Dewey] is a promising perennial grain candidate that The Land Institute has been directly domesticating since 2001. Grain from improved IWG can be sold under the trademark Kernza.

Genome‐wide association study identifies genomic regions under selection for domestication and agronomic traits in intermediate wheatgrass

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Intermediate wheatgrass (IWG) (Thinopyrum intermedium, Kernza) is a perennial forage grass undergoing neo‐domestication as a grain crop. IWG provides numerous ecosystem services and has the potential to benefit rural communities as an alternative crop option with high market value.

Genotype‐by‐environment interactions influence grain yields of intermediate wheatgrass

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Crop rotation with perennial grain crops, such as intermediate wheatgrass (IWG; Thinopyrum intermedium), marketed as Kernza, promotes agroecological intensification and environmental sustainability relative to annual cropping systems. To assess yield performance and adaptability of IWG breeding populations across diverse environments ...
