Beans, Peas, Soy & Co.: EU Project Promotes Cultivation of Pulses in Europe

Fewer imports, less fertiliser, more sustainability – there are good reasons for expanding the cultivation of pulses in Europe. Up to the present, the valuable protein-rich plants are cultivated in very few areas. The EU project TRUE with partners from 10 countries wants to change that. Researchers from the University of Hohenheim are part of the project. They are examining case studies, finding the economic effects, and ensuring an exchange of knowledge among the project partners. For this work, they are receiving over 540,000 euros from the 5-million-euro project – one of the major research projects at the University of Hohenheim.

Legumes are a very special type of crop, they are characterised as a sustainable source of highly nutritious food and feed. ‘Sustainable’, since legumes require no inorganic nitrogen fertiliser, and this efficiency saving is added to by improvements to soil qualities and total productivity when deployed in a modern crop rotation. The nitrogen demand of legumes is met naturally via a symbiosis with soil bacteria that is contained in legume root nodules.

Despite their benefits, legume based systems have not been adopted in common farming practice, due largely to the fact that their potential profitability is questioned. Pulses only grow on 2-3 per cent of the arable land in the EU. That makes the EU highly dependent on imports of feed-legumes and fossil energy, which is required for the production of inorganic nitrogen fertilisers.

A new, European-wide research project intends to change this. Plant cultivation experts, agricultural economists, and the Hohenheim Research Center for Global Food Security and Ecosystems (GFE) from the University of Hohenheim are participating. In the project TRUE (TRansition paths to sUstainable legume-based systems in Europe), 24 project partners from 10 European countries and Kenya have gotten together to explore and develop sustainable legume-based farming systems and agri-feed and food chains in the EU. The group includes not only researchers from different backgrounds, but also businesses operating in legume commodity production and processing and other actors from the practice.

Legumes reduce need for mineral fertilisers

At the University of Hohenheim, plant cultivation expert apl. Prof. Dr. Sabine Gruber is carrying out two of the 24 total case studies in the project together with Dr. Sabine Zikeli, Coordinator for Ecological Agricultural and Consumer Protection. The researchers are focusing on the successful history of lentils and soy. Their data is to help better understand why these two types of legumes are so successful.

Project TRUE aims to unite economy and ecology

At the University of Hohenheim, the agricultural economists under the leadership of Prof. Dr. Enno Bahrs and Prof. Dr. Christian Lippert are looking at the economic side of legume cultivation. The lack of yield security and economic efficiency are considered the largest obstacles currently. The researchers are examining what economic effects would arise from expanding cultivation and whether production would be competitive.

The work at the University of Hohenheim is being coordinated by the Hohenheim Research Center for Global Food Security and Ecosystems (GFE).

Innovation for more healthy and profitable legume-based products

The whole diversity of available legume species and pedo-climatic conditions across Europe is covered by TRUE, looking at 24 case studies from the production and use of crops such as beans or chickpeas for healthy dishes in Portugal, to the processing of peas into beverages in the UK to the marketing of organic traditional lentils in Germany.

TRUE innovates across the supply chain – from the development of novel farming practices such as the use of pulses as “vegetable fertilisers” or “living manures”, to the testing of new food technologies for improved feed and food formulation. Feed innovations include use of lupins and faba beans for novel aquaculture feeds. Additionally, there will be sustainability assessments of various legume-based systems.

Project TRUE aims to unite economy and ecology

TRUE wants to harness the environmental and social benefits and potentials of legumes, e.g. reducing environmentally damaging greenhouse gas emissions and water pollution as well as for a healthier nutrition with high value proteins while at the same time increasing the commercial competitiveness of EU grown legume crops. Specific recommendations will be proposed to influence relevant policies, such as the EU’s Common Agricultural Policy.

TRUE invites legume stakeholders to connect with the project to build a European network for the promotion of these crops.

Background: Project TRUE – TRansition paths to sUstainable legume-based systems in Europe

The University of Hohenheim is part of a wide European consortium that has been successful in receiving a €5 million grant from the EC’s Horizon 2020 programme “Sustainable Food Security (SFS) – Resilient and resource-efficient value chains”. The project with the acronym “TRUE” (TRansition paths to sUstainable legume-based systems in Europe) involves 24 project partners from 11 countries – Croatia, Denmark, Germany, Great Britain, Greece, Hungary, Ireland, Portugal, Slovenia, Spain, and Kenya, including scientists, businesses operating in legume commodity production and processing and other actors from the practice.

The consortium is coordinated by Dr. Pietro Iannetta, who is based at the James Hutton Institute ( in Scotland, UK.
