Abiotic and biotic context dependency of perennial crop yield. [PDF]

PLoS ONE, 2020
Perennial crops in agricultural systems can increase sustainability and the magnitude of ecosystem services, but yield may depend upon biotic context, including soil mutualists, pathogens and cropping diversity.

Community structure of soil fungi in a novel perennial crop monoculture, annual agriculture, and native prairie reconstruction. [PDF]

PLoS ONE, 2020
The use of perennial crop species in agricultural systems may increase ecosystem services and sustainability. Because soil microbial communities play a major role in many processes on which ecosystem services and sustainability depend, characterization ...

Metabolome fingerprinting reveals the presence of multiple nitrification inhibitors in biomass and root exudates of Thinopyrum intermedium [PDF]

Plant-Environment Interactions
Biological Nitrification Inhibition (BNI) encompasses primarily NH4+‐induced release of secondary metabolites to impede the rhizospheric nitrifying microbes from performing nitrification.

Perennial Kernza cropping promotes rhizosphere microbiome stability and endophyte recruitment compared to annual wheat [PDF]

Environmental Microbiome
Background Perennial cropping systems are increasingly recognized for their potential to enhance microbial biodiversity and beneficial soil functions compared to annual crops.

Towards a practical theory for commercializing novel continuous living cover crops: a conceptual review through the lens of Kernza perennial grain, 2019–2022

Frontiers in Sustainable Food Systems, 2023
As agricultural scientists rapidly develop and deploy novel continuous living cover (CLC) crops and cropping systems such as perennial grains, a growing number of intermediaries are engaged in advancing the commercialization, adoption, and scaling of ...

Comparative simulation of crop productivity, soil moisture and nitrate-N leaching losses for intermediate wheatgrass and maize in Minnesota using the DSSAT model

Frontiers in Sustainable Food Systems, 2023
Perennial grain crops are a potential alternative source of staple foods and animal forage that can also provide additional environmental benefits over annual crops.

Agronomic assessment of two populations of intermediate wheatgrass—Kernza® (Thinopyrum intermedium) in temperate South America

Grassland Research, 2022
Background Kernza® intermediate wheatgrass is a perennial grain and forage crop that can provide several ecosystem services. Major research efforts focused on Kernza have taken place in high latitudes.

Intercropping legumes and intermediate wheatgrass increases forage yield, nutritive value, and profitability without reducing grain yields

Frontiers in Sustainable Food Systems, 2022
IntroductionKernza intermediate wheatgrass (IWG) is a perennial grain and forage crop. Intercropping IWG with legumes may increase the forage yields and nutritive value but may compromise Kernza grain yields.

How the Nitrogen Economy of a Perennial Cereal-Legume Intercrop Affects Productivity: Can Synchrony Be Achieved?

Frontiers in Sustainable Food Systems, 2022
The UN's Sustainable Development goal of Zero Hunger encompasses a holistic set of targets that range from ending hunger by 2030, to increasing environmental sustainability and resilience of food production.

Simulating the effect of perennialized cropping systems on nitrate-N losses using the SWAT model

Frontiers in Agronomy, 2023
Several newly released crop varieties, including the perennial intermediate wheatgrass (grain marketed as Kernza®), and the winter hardy oilseed crop camelina, have been developed to provide both economic return for farmers and reduced nutrient losses ...
