| There is a pressing need to develop arable cropping systems that are both more efficient in their use of nitrogen (N) and more resilient to an increasingly variable and unpredictable climate. One potential solution is to use species-rich mixtures of grasses and legumes in the fertilitybuilding phase of a ley/arable crop rotation. These mixtures may reduce N losses and increase productivity of the following crop. They may also have other important benefits such as increased in-field biodiversity. In this project, legume and grass species with a range of tolerances to different environmental conditions, and with differing growth characteristics, are being grown individually and as a mixture across the UK, and their performance assessed. |

| The EU regulation requiring organic farmers to use 100% organic herbage seed is looming closer. Currently they are ‘enjoying’ a derogation from this because suitable seed is not available. For 2004 seeds mixtures had to contain at least 50% organic seed. This breathing space before full 100% organic seed is required is giving the organic industry time to improve the availability of suitable species and varieties. Historically there was a viable herbage seed production industry in the lowland and southern areas of Wales. This area turned to livestock production during its more profitable periods, with specialist arable and herbage seed production switching largely to south east England. The agronomic potential remains in Wales but now needs to be developed... |

| The ability of different legume cover crops to suppress annual weeds during the early establishment phase was compared using a simulation model of inter-plant competition and field observations. Height, partitioning parameters, extinction coefficients, crop density and time of emergence were recorded for 11 species sown in monocultures. A naturally occurring population of fat hen (Chenopodium album) was present on the experiment. The competition model was run to compare the expected suppressive ability of the different species on this weed. Samples of C. album were also taken from each plot immediately prior to cutting to provide some empirical observations. Predicted suppressive ability was correlated with seed size and height with large seeded, tall... |
