DKK 60 M for legume innovation to drive future food production

Legume protein will play a major role in future food production, but legumes have long been overshadowed by cereals in terms of research and development investments. The Novo Nordisk Foundation has now supported the N2CROP center for legume innovation with DKK 60 million to accelerate the optimization of legumes as food crops.

The mission of N2CROP is to establish an international hub for cutting-edge grain legume research and innovation and, ultimately, achieve sustainable agri-food systems powered by biologically fixed nitrogen to deliver high-quality plant food protein.

Center leader Stig U. Andersen states: “We are thrilled to bring diverse expertise together within N2CROP to tackle a major challenge in food production and look forward to broad collaborations with all parties interested in legume innovation.”

N2CROP connects various disciplines, including nutrition (bioavailable legume seed protein and plant cell walls), microbiology (optimization of nitrogen fixation through customized rhizobium inoculants), genetics (targeted mutations to enhance key legume traits), and agronomy (field trials and crop modelling) with the ambition to improve legume mixed crop performance to a level where legume-cereal intercropping will generally outcompete cereal monoculture.

Martin Weih, professor at the Department of Crop Production Ecology at SLU, explains the role of SLU at the center: "SLU is responsible for planning, implementing and evaluating a series of field trials where various mutagenic lines of field bean with altered properties are intercropped with wheat and oats. The changed field bean properties imply that the nitrogen fixing capacity of the field bean is maintained even with the higher fertiliser levels that are appropriate for wheat and oats in an intercrop. Furthermore, SLU is also responsible for modelling the effects that intercrops with the new plant material gives on various sustainability aspects, and compared to cultivation in pure stands. SLU thus has a very central role in this project, which integrates biotechnology, plant ecology and agronomy in a fantastic way."

Background

The vast majority of grain crops are grown as nitrogen-fertilized monocultures to achieve high yields and processing efficiency. The downsides are the large energy input required for the production of chemical nitrogen fertilizers and the risk of severe crop losses due to pests and diseases that have to be chemically controlled. 

In contrast, mixed- or intercropping systems have successfully taken advantage of legumes and nitrogen fixing bacteria. For example, perennial clover-grass pastures represent a biodiverse growth system that offers strong resistance against diseases and pests. The biomass and protein produced in these systems is not, however, suitable for food use without application of complex processing methods that are still being established. 

Developing legume-based mixed cropping systems for grain crops – such as faba bean and cereals – holds significant potential for reducing dependence on chemical nitrogen fertilizers and pesticides. The challenge is that legumes and legume-based mixed cropping systems are not generally economically competitive.
