Yield data on winter sown oilseed rape plants, in relation to pollination by insects and in relation to the ecosystem services provided by beneficial insects. Data includes yield assessed for entire field, whole plant and within different parts of the plant (per raceme and per pod). These data can be linked to the related natural enemy data set and the pollinator data set collected as part of the Wessex BESS project, funded by the NERC Biodiversity and Ecosystem Service Sustainability research program.
