A joint Nordic project investigates the suitability and performance of the perennial grain Kernza (Thinopyrum intermedium) under Finnish conditions. The species is native to Europe or Eurasia, and its plant breeding began in the United States in the 1980s. Kernza produces a grain yield that can be used for food in a similar way to conventional cereals, while the vegetative biomass is suitable for animal feed. Kernza is characterized by an exceptionally deep root system, which makes its potential for erosion control and for increasing soil organic matter and carbon sequestration of particular interest.
In the joint Nordic NordForsk project, the establishment of Kernza is studied both as a monoculture and in mixtures with legumes, as well as the optimization of nitrogen fertilization and yield formation over three to four growing seasons. Field experiments are conducted at Luke in Jokioinen, and the crop is also tested at the Tervola school farm. Observations include spring regrowth, stand density, and heading. In addition, crop samples are taken prior to harvest for yield component determinations and chemical analyses. Soil samples are used to monitor changes in soil carbon content.
Stakeholders include agricultural schools and Rural Women's Advisory Organization. The field experiments are carried out using harmonized protocols in five countries: Lithuania, Norway, Sweden, Finland, and Estonia. The project is coordinated by SLU, the Swedish University of Life Sciences. The project started in 2023 and will conclude in early 2027.
The project consists of seven work packages, four of which involve Luke:
WP 1 Kernza cultivation systems for grain production
WP 3 Winter hardiness and adaptation to growth conditions in Nordic Baltic countries
