Towards a practical theory for commercializing novel continuous living cover crops: a conceptual review through the lens of Kernza perennial grain, 2019–2022
Staff at The Land Institute, Michael Fields Agricultural Institute, and the University of Minnesota discuss what is required to build developmental frameworks for novel continuous living cover (CLC) crops and…
Photosynthetic capacity, canopy size and rooting depth mediate response to heat and water stress of annual and perennial grain crops
Climate-resilient crops are becoming increasingly desired as global climate patterns continue to shift. This paper looks at the ability of perennial grains to adapt to warmer and drier growing conditions…
Soil total carbon and nitrogen under long-term perennial bioenergy crops receiving various nitrogen fertilization rates
A long-term study conducted in the northern Great Plains region of the US indicates that perennial crops such as intermediate wheatgrass (Kernza) may sequester greater amounts of soil carbon and…
David Pimentel consistently promoted perennial grains as the future of agriculture
Authors Tim Crews and Sienna Polk pay homage to influential entomologist and Cornell University professor David Pimentel, who was widely known for his numerous studies on the energetics of traditional…
Forage harvest management impacts “Kernza” intermediate wheatgrass productivity across North America
Research into the productivity of Kernza as a forage and grain crop examines the plant’s profitability associated with its dual-purpose nature, the mechanisms driving increased productivity of the crop, and…
Adaptation of pathogens to their local plant host, Silphium integrifolium, along a precipitation gradient
Featuring five researchers from The Land Institute, this manuscript documents the prevalence of plant pathogens associated with human-induced changes to the planet’s climate and ecosystems, with the perennial prairie plant…
Evaluation of the Intra- and Interspecific Development of Different Accessions of Silphium perfoliatum L. and Silphium integrifolium Michx.
Research from The Land Institute’s collaborators in Germany details the use of perennial species for biomass production, with the goal of analyzing the value of Silphium for the energy production…
Nitrate leaching losses and the fate of 15N fertilizer in perennial intermediate wheatgrass and annual wheat — A field study
Recent research in ecology illustrates the advantage that perennial grains like Kernza (intermediate wheatgrass) possess in reducing nitrate leaching when compared to popular annual grain crops like wheat, as the…
Genomic insights into the NPGS intermediate wheatgrass germplasm collection
The Land Institute’s Lee DeHaan (Lead Scientist, Kernza) and Sajal Sthapit (Postdoctoral Researcher, Kernza) worked with research collaborators to release this publication detailing the value of the USDA’s National Plant…
Sensing Scale in Experimental Gardens: Un-Lawning With Silphium Civic Science
By designing transdisciplinary and participatory methods of engagement, The Land Institute’s Civic Science Program harnessed public participation to visualize cross-scalar relationships in gardening projects through the medium of Silphium integrifolium,…
Agronomic assessment of two populations of intermediate wheatgrass-Kernza® (Thinopyrum intermedium) in temperate South America
Recent research with Intermediate Wheatgrass in Uruguay highlights for the first time the agronomic performance of Kernza in a low-latitude region with mild winters, which will be vital towards efforts…
Domestication effects on nitrogen allocation, internal recycling, and nitrogen use efficiency in the new perennial crop Silphium integrifolium (Asteraceae)
Abstract Improvements in seed yield during domestication and breeding are frequently achieved moving plants from the conservative syndrome of the plant economic spectrum towards the more acquisitive side, changing how…
