Optimising competitiveness, reliability, nutrient cycling and utilization of spring lupins in the UK

LISA is a five-year program of collaborative research on the role of spring lupins in UK agriculture. It forms a comprehensive evaluation of the advantages and disadvantages of this crop within organic and conventional agriculture for arable and mixed livestock/arable systems. On farm nutrient budgets, crop competitiveness and weed control, feed utilization for ruminant and non-ruminants, and emissions from animal wastes are being assessed in comparison with other grain legumes. The potential of lupins to increase the efficiency of nitrogen (N) and phosphorus (P) use is emphasized. Molecular markers for key traits will be identified and brought together with improved germplasm as a 'breeder's toolkit' for further lupin improvement. The need to improve yield, yield stability, earliness of maturation, and tolerance of alkaline soils have been identified. Crimping technologies are being evaluated to assess the potential for early harvesting of lupins in marginal growing areas. The dissemination of practical information to UK farmers and other beneficiaries is a major element of the project
