Evaluation of Andean lupin (L. mutabilis) in comparison to white (L. albus) and narrow-leafed lupin (L. angustifolius) for energy recovery
Project
Project code: JKI-ZL-08-3180
Contract period: 01.03.2014
- 28.02.2017
Purpose of research: Applied research
At present, maize is the predominant crop for biomass production in Germany. Its high incidence in crop rotations calls for alternative crops which are suited for herbal biomass production as well. Due to their manifold ecosystem services, lupins have the potential to contribute to diversified crop rotations. The present research project compares Andean lupin (L. mutabilis), white lupin (L. albus), and narrow-leafed lupin (L. angustifolius) in their efficacies to produce biomass for energetic purpose. In addition to cultivars of Andean lupin and white lupin, fast-growing prebreeding lines of narrow-leafed lupin developed at JKI will be included in the analyses. The trials will be grown at two sowing times to assess the ability for main crop and catch crop (e. g., in succession of forage rye) use, respectively. Besides the commercial varieties of Andean lupin, a sample of plant genetic resources of L. mutabilis will be evaluated in the field to identify fast growing biomass types, and subsequently tested for their biomass performance, too. In addition to classical traits like biomass and total dry matter yield the attainable biogas and methane yields as well as key ingredients will be assessed. The project is expected to contribute to (i) diversified crop rotations for bioenergy production, (ii) increased diversity in agricultural landscape and (iii) to a more sustainable energy supply. This research project compares Andean lupin to white and narrow-leafed lupins regarding their efficiency as renewable energy sources and their potantials to enhance crop diversity in agriculture. Field trials for assessing the biomass potantials of these species were conducted at two dates for sowing to address the possibility of main crop and catch crop use, respectively. Early sowing datewas in most instances superior to late sowing, with highest mean total dry matter yields (TDMY) at Groß Lüsewitz experimental station . Outstanding TDMY (max. 160,0 dt/ha over 2 years and 3 locations) were reached by an entry of L. mutabilis . Besides commercial varieties of Andean lupin, a sample of plant genetic resources of L. mutabilis was evaluated in the field and fast-growing biomass types were identified.
