Carbon and water relations in perennial Kernza (Thinopyrum intermedium): An overview
Plant Science, 2020Perennial crops have been proposed as a more sustainable alternative to annual crops, because they have extended growing seasons, continuous ground cover, reduced nutrient leakage, and sequester more carbon in the soils than annual crops. One example is intermediate wheatgrass (Thinopyrum intermedium), a perennial crop that has been used as a cool ...

Forage harvest management impacts “Kernza” intermediate wheatgrass productivity across North America
Agronomy Journal, 2023 AbstractIntermediate wheatgrass [IWG, Thinopyrum intermedium (Host) Barkworth & D.R. Dewey, trade name Kernza] is a widely adapted, cool‐season forage grass, actively bred for perennial grain production. Most of IWG's net primary productivity is directed to nonreproductive structures, so dual‐use strategies to harvest both grain and forage ...

Energy, water and carbon exchange over a perennial Kernza wheatgrass crop
Agricultural and Forest Meteorology, 2018Abstract The ecological impacts resulting from global warming and conventional agricultural practices are predicted to affect crop productivity and reduce the land area available for agriculture in the near future. Perennial crops can sustain high yields without replanting for numerous consecutive years, resulting in important climate benefits.

Soil and Water Quality Rapidly Responds to the Perennial Grain Kernza Wheatgrass
Agronomy Journal, 2013Perennial grain cropping systems could address a number of contemporary agroecological problems, including soil degradation, NO3 leaching, and soil C loss. Since it is likely that these systems will be rotated with other agronomic crops, a better understanding of how rapidly perennial grain systems improve local ecosystem services is needed.

Expansion of perennial grain and forage Kernza intermediate wheatgrass to temperate regions may be limited by its vernalization requirements. We compared vegetative and reproductive traits of Kernza plants grown in the greenhouse under four environmental treatments of temperature and day length for a 7 week induction period. The percent of plants that

‘MN‐Clearwater’, the first food‐grade intermediate wheatgrass (Kernza perennial grain) cultivar
Journal of Plant Registrations, 2020Abstract‘MN‐Clearwater’ (Reg. no. CV‐287, PI 692651) is the world's first commercial food‐grade intermediate wheatgrass [IWG; Thinopyrum intermedium (Host) Barkworth & D.R. Dewey subsp. intermedium] grain cultivar. It was developed as a synthetic population at the University of Minnesota, St. Paul, MN, and released in August 2019.

Production of Dual-Use Perennial Grain Kernza® in a humid continental environment
Canadian Journal of Plant ScienceKernza performance was evaluated over three years in Quebec to assess how intercropping with legumes and altered precipitation influence grain and forage yields of this novel dual-purpose crop. Grain yields were low and declined sharply regardless of intercropping, while forage yields and quality were generally higher in intercrops and stable across ...

Intercropping dynamics in a perennial Kernza cropping system
A research agenda has been undertaken to perennialize agrarian landscapes in response to structural issues inherent to annual agricultural production, which compromise the sustainability and resiliency of cropping systems. These issues include soil erosion, nutrient runoff, declining soil organic matter stocks, and poor water relations.openaire +1 more source
