Abstract
Growing cereals in a leguminous living mulch (bi-cropping) could potentially
reduce the need for synthetic inputs to cereal production while preventing losses
of nutrients and increasing soil biological activity. The objective of this project
was to investigate how bi-cropping (a low input production system for cereals)
would compare with conventional winter wheat production systems in terms of
total biomass, grain yield and biological diversity. This study has resulted in valuable information on bi-cropping being generated as
well as identifying the potential benefits that can be expected under Irish
conditions. While the results indicate that winter wheat can be successfully
established in an understorey of white clover if sown early in good conditions,
competition from grass weed species represents a serious impediment to successful bi-cropping in the longer term. Consequently further research is
needed before such a system can be presented to the agricultural community.
