Kernza® CAP

Collaborating for perennial transformation

Can agriculture meet the challenges of our future food system while also protecting our water and soil, providing economic opportunities, and promoting social wellbeing? 
We believe it can.

This work is supported by AFRI Sustainable Agricultural Systems Coordinated Agricultural Program (SAS-CAP) grant no. 2020-68012-31934 from the USDA National Institute of Food and Agriculture.

  • The USDA SAS CAP program funded a five year grant, “Developing and deploying a perennial grain crop enterprise to improve environmental quality and rural prosperity”
  • Activities began 9/1/2020
  • Farmers, researchers, and public and private sector partners working together
  • Research, education, commercialization, and policy innovations to scale up Kernza®
  • Advance the environmental sustainability of food production
  • Demonstrate the viability of new perennial cropping systems as real economic opportunities for farmers and rural communities

The Kernza® CAP grant has a grand vision

The current situation

Nearly half of all global row crop land is used to grow three annual crops – wheat, maize, and rice – that provide more than 50% of human calories (FAO, 2019). Many annual crops like these rely on tillage resulting in soil loss, greenhouse gas emissions, and reduced soil health (Pimentel et al., 2012). The deterioration of soil from current annual row crop agriculture also reduces crop yields and increases farmer dependence on costly agrochemicals.

Focus on shifting agriculture from annual to perennial systems

Kernza® has a deep root system that provides multiple environmental benefits, including improving water and soil quality and reducing soil erosion. Additionally, research has shown that this new perennial grain can increase farm income due to decreased inputs and costs from reduced tillage, pesticide requirements and nutrient losses. The Land Institute holds the trademark license for Kernza® and uses its associated royalties to collect data and disseminate the most relevant information to farmers and stakeholders.

One of humanity's biggest challenges

We are striving to create a sustainable agricultural system where farmers, businesses, communities and consumers benefit from healthier soils, cleaner water, stronger economies and more resilient social networks. We believe perennials are the key to the future of agriculture and that Kernza® can lead the way.

Kernza® CAP has six objectives


The six Kernza® CAP grant objectives

1. Advance germplasm and trait evaluation


Project Leads:
James Anderson, University of Minnesota
Prabin Bajgain, University of Minnesota
Lee DeHaan, The Land Institute

Project Team:
George Annor, University of Minnesota
Jared Crain, Kansas State University
Pam (Baraem) Ismail, University of Minnesota


The goal of this objective group is to improve Kernza® genetics for increased grain yield, ecosystem services, and functionality as a new food ingredient. Our work will be closely integrated with the Environmental Quality objective group to identify future Kernza® varieties optimized for specific environmental outcomes.  We will integrate with the Agronomy objective group to determine how future Kernza® varieties respond to fertilization across a broad range of growing conditions. Our team will update and optimize existing Kernza® genomic selection (GS) models by evaluating training and breeding populations and incorporating food science traits into the models to identify future varieties with grain that stores and performs well in various food products.


  1. Assessment of agronomic traits including grain yield, seed size, plant height, resistance to shattering and free grain threshing, with identified superior trait performances used to develop future Kernza® varieties.
  2. Screen five variety candidates managed under different agronomic conditions for overall nutrient composition, including protein, fat, starch, dietary fiber, and antioxidants.
  3. Conduct storage stability tests on grain harvested from variety trials to understand optimal storage conditions and timing.
  4. Measure relationships between root traits and grain traits to explore potential genetic synergies or tradeoffs between ecosystem services and yield.
  5. In collaboration with the Agronomy objective group, replicate field and on-farm experiments at six or more locations, with a minimum core set of treatments, including NPK fertility trials, that will be deployed across the full geographic reach of the Kernza®CAP project.

2. Enhance agronomic and on-farm knowledge

The goal of this objective group is to advance our knowledge and understanding of Kernza® agronomy and on-farm knowledge. We will accomplish these goals by conducting both research field trials and on-farm field trials in close collaboration with the Breeding objective group and growers located throughout the U.S. Results from these trials will inform future management recommendations and will be shared in field days, educational materials, and programming developed by the Education, Extension, and Policy objective group.


  1. Launch two field trials to evaluate management practices that maximize productivity and persistence, guide future fertility recommendations, and update management practice recommendations for improved grain yields and grain quality.
    • Field Trial #1 is a variety trial that will explore how genotypes managed in identified environments interact. (Commonly called a GxExM experiment, genotype by environment by management). Kernza® genetic lines from the breeding programs will be evaluated under two levels of fertilization to determine how varieties respond to differences in nutrient application.
    • Field Trial #2 is a fertility trial that will examine N, P and K fertilizer rates and application timing. Additionally, grain and forage yield in summer after harvest and at fall, and nutrient content of grain and forage will be measured to determine which fertilization strategy maximizes grain and forage yields.
  2. Conduct on-farm trials in collaboration with Kernza® growers to integrate grower experience and knowledge into research strategies and address regionally specific management practices to better address the different growing regions of the U.S.
    • Trial sites will also host Extension and outreach activities described in the Education, Extension, and Policy objective group and will provide case-study examples for curricula modules and data for water quality model validation.

The goal of this objective group is to determine which Kernza® management strategies best improve environmental quality in comparison to “business as usual” annual cropping systems. Our work will be closely integrated with the Agronomy team field and farm trials and the growers who are partnered on the grant. Research outcomes from our work will be incorporated into the Kernza® grower management guide, curriculum developed by the Extension, Education and Policy team, and shared with industry stakeholders, including the Kernza® Stewards Alliance.


  1. In coordination with Agronomy and Breeding objective groups, instrument experimental plots to measure surface runoff, soil moisture, and nitrate levels in soil water beneath the rooting zone.
  2. Calibrate and validate crop-soil hydrology models to understand water quantity and quality characteristics of Kernza® at a watershed scale.
  3. Estimate the GHG footprint of Kernza® using biophysical models based on carbon flux data collected with eddy flux towers and static chambers.
  4. Validate crop and water quality models using data from all field trials, with a focus on grain yield, aboveground biomass, root biomass, and  carbon dynamics.
  5. Conduct model simulations to assess climate change impacts (altered precipitation and temperature) on Kernza® GHG emissions and environmental quality.
