An experiment was carried out at Uppsala, Sweden, to study the effects of mineral nitrogen (N) fertilization on sward light climate and white clover growth and morphology during a summer regrowth in a mixed meadow fescue/white clover sward. It is suggested that the rapid clover height increase after N application is a photomorphogenic response, triggered by the reduced R:FR ratio of the light, in turn caused by the effects of N on grass growth and colour. Earlier observations, indicating that the number of stolon growing points is also affected very early after N application, at a time when only R:FR ratio but not the light penetration has decreased as a result of this treatment, could not be verified in the present study
