A study of the vernalisation requirements of mountain rye (Secale strictum syn. S. montanum) may help explain low grain yields of perennial cereals compared to wheat
Australian research partners are examining the potential of mountain rye as a suitable perennial grain crop candidate for Australian grazing and cropping systems, and their recent research on vernalization (a…
Putting the P(ee) in perennial agriculture: Reflections on a workplace urine reclamation project
Land Institute researchers Madeline DuBois, Laura van der Pol, Aubrey Streit Krug, and Timothy Crews share findings from a human urine nutrient reclamation project conducted in the workplace and research…
Modeling carbon allocation strategies for high-yielding perennial crops
The Land Institute’s Lee DeHaan and Tim Crews co-authored a paper with colleagues from Loyola University that documents a model outlining the path to breeding high-yielding perennial crops that balance…
Perennial rice – An alternative to the ‘one-sow, one-harvest’ rice production: Benefits, challenges, and future prospects
With a high-yielding perennial rice variety moving onto landscapes in Asia and Africa, researchers from the Indian Institute of Rice Research (ICAR) and the International Rice Research Institute (IRRI) released…
Choice of companion legume influences lamb liveweight output and grain yields in a dual use perennial wheat/legume intercrop system
Research partners in Australia analyzed the role of perennial wheat, a crop in development at The Land Institute, as a dual-purpose grain and forage crop. The authors of this study…
Breeding Potential for Increasing Carbon Sequestration via Rhizomatous Grain Sorghum
Building on existing knowledge of perennial sorghum development through The Land Institute’s breeding program and considerations around the benefits of perennial grain agriculture through research from The Land Institute and…
Genetic variation and heritability of agronomic traits in a native perennial forage species from drylands: breeding potential of Festuca pallescens
A research cohort with scientists from the University of Wisconsin Madison and CONICET in Argentina assessed the potential of Festuca pallescens, a native, perennial forage grass species of Patagonia, for…
Soil microbial and plant biomass carbon allocation within perennial and annual grain cropping systems
Research collaborators from the University of Minnesota published a study indicating that perennial cropping systems with intermediate wheatgrass (Kernza) can sustain soil microbial activity and maintain higher root production than…
The microbiome of a perennial cereal differs from annual winter wheat only in the root endosphere
An international research cohort affiliated with universities and groups in Austria, Poland, Germany, France, Belgium, Sweden, Kenya, and the United Kingdom published a study looking at belowground biodiversity of microbes…
Flour composition, dough, and bread properties of intermediate wheatgrass (Thinopyrum intermedium) compared to annual wheat species
Researchers in Norway released findings around the properties of Kernza perennial grain in flour, dough, and bread compared to annual wheat using intermediate wheatgrass provided by Lee DeHaan, The Land…
Improving the Nutritional Profile of Intermediate Wheatgrass by Solid-State Fermentation with Aspergillus oryzae Strains
Research collaborators Takehiro Murai and George A. Annor from the University of Minnesota’s College of Food, Agricultural, and Natural Resource Sciences analyzed the use of Kernza in fermentation and the…
Introducing intermediate wheatgrass as a perennial grain crop into farming systems: insights into the decision-making process of pioneer farmers
Research collaborators at ISARA-Lyon in France conducted an analysis to better understand farmer needs related to Kernza production, including integration of the crop into existing systems, agronomic needs, and insights…
