title: Competitive ability of grain legume-barley intercrops towards volunteer crops and weeds creator: Hauggaard-Nielsen, Henrik creator: Tranberg Nikolajsen, Jacob creator: Steen Jensen, Erik subject: Crop combinations and interactions description: Field pea (Pisum sativum L.) and blue lupin (Lupinus angustifolius L.) were either sole cropped or inter-cropped with barley (Hordeum vulgare L.) at two levels of nitrogen application to determine the effects of interspecific interaction in an intercrop and nitro-gen fertility on competitive ability towards volunteer crops - exemplified by red clover (Trifolium pratense). The dynamically change of competitive ability by intercropped species over time was shown to be im-portant in order to reduce opportunities for growth of volunteer crops and weeds date: 2006 type: Conference paper, poster, etc. type: NonPeerReviewed format: application/pdf identifier: http://orgprints.org/7474/1/Volonteer_pb_lb_proced_v4.pdf identifier: Hauggaard-Nielsen, Henrik; Tranberg Nikolajsen, Jacob and Steen Jensen, Erik (2006) Competitive ability of grain legume-barley intercrops towards volunteer crops and weeds.
