Abstract
ABSTRACT Results are presented to show the effect of white clover ( Trifolium repens ) and of applied N on the hotanical composition of swards sown with perennial ryegrass ( Lolium perernne ), timothy ( Phleum pratense ), meadow fescue ( Festuca pratensis ) and mixtures of two and three of these species. White clover had a more favourahle effect on the growth of perennial ryegrass than on either timothy or meadow fescue both in terms of yield and in terms of tiller numbers. Tiller numbers of rough‐stalked meadow grass ( Poa trivialis ) were increased and tiller numbers of Agrostis species were reduced by application of N and by inclusion of clover. Possible reasons for these effects are considered.
