This study investigated N2-fixation and total N yield in grassland mixtures including different combinations of red clover, perennial ryegrass and three deep rooted forbs: chicory, ribwort plantain and caraway, managed without and with slurry application. The percentage of clover N derived from atmosphere (%Ndfa) increased in mixtures, but was unaffected by inclusion of forbs. However, forbs affected the quantity of N2-fixation and total N yield by affecting the red clover proportion in the mixtures. Mixtures composed of grass,clover and plantain or caraway showed higher N2-fixation and N yield than with chicory included. Slurry application reduced N2-fixation due to decreasing clover contents in the sampled biomass. The study highlighted differences among forbs in their influence on legume N2-fixation and total N yield showing that forbs can be included in grasslands without negative effects on red clover performance. date: 2016 date_type: published publication: Grassland Science in Europe volume: 21 full_text_status: public pagerange: 576-578 contact_email: jorgen.eriksen@agro.au.dk conf_subm: not_subm fp7_project: no access_rights: info:eu-repo/semantics/openAccess citation: Dhamala, NR; Rasmussen, J; Carlsson, G; Søegaard, K and Eriksen, J (2016) Nitrogen fixation in red clover grown in multi-species mixtures with ryegrass, chicory, plantain and caraway.
