    Uittreksel

    Nitrogen (N) fertilisation on grassland under cutting conditions in Flanders (Belgium) is currently restricted to 300 kg ha-1 N available from organic and chemical fertilisers. Combining perennial ryegrass (Lolium perenne, Lp) with red (Trifolium pratense, Tp) and white clover (Trifolium repens, Tr) is a possible alternative to achieve high crop yields and quality, at lower N fertilisation levels. On a farm in Moortsele and in Nieuwenhove with sandy loam soils, a paddock (> 0.75ha) was divided and one half was sown with a mono culture Lp and the other half with a Lp/Tp+Tr mixture. N fertilisation was in accordance with fertiliser recommendations i.e. Lp: 285 kg Navailable ha-1 year-1 and Lp/Tp+Tr: 180 kg Navailable ha-1 year-1. Dry matter crop yields under cutting management (four - six cuts per year) were measured over four years. Grass clover swards resulted in an additional dry matter yield of +2 t ha-1 year-1 and +0.5 t ha-1 year-1 in Moortsele and Nieuwenhove, respectively while 86 kg N ha-1 year-1 and 81 kg N ha-1 year-1 of chemical N fertiliser was saved in Moortsele and Nieuwenhove, respectively during the same period.
