摘要

The majority of previous studies into the incorporation of white clover (Trifolium repens L.) in perennialryegrass (Lolium perenne L.) swards in dairy production systems have been at low nitrogen fertiliser (N) (< 150 kg N/ha)and low stocking rate (SR; < 2 livestock units/ha) levels whereas high N levels and high SR favour optimum herbage drymatter (DM) production in grass-only (GO) systems. Increasing artificial N decreases sward white clover proportion ingrass-clover (GC) swards (Carlsson and Huss-Danell, 2003), and increasing SR on GC swards can result in damage towhite clover plants. However, under high N levels, a high SR can minimise the negative effects of increased grass growthon white clover proportions (Harris and Clark, 1996). The objective of this study was to examine the effects of white cloverinclusion on herbage DM production in an intensive animal grazing system, under high N fertiliser (250 kg N/ha) and highSR (2.75 LU/ha) levels over a 3-year period (2014-2016).
