Abstract A simulated grazing field experiment was conducted to determine the effect of timing and intensity of grazing on the growth and yield of a mid-late maturing spring wheat (cv. Flanker) under different watering regimes, at Wagga Wagga in southeastern Australia. The experiment was a factorial design of watering regime and pasture “grazing” as factors, with three replications. The two watering regimes were rainfed (R) and supplemental irrigation (I). There were four simulated grazing treatments: no grazing, “crash” grazing by mowing to 5 cm height on 13 June (Cut1-5), “crash” grazing by mowing to 5 cm on 15 July (Cut2-5) and “clip” grazing by mowing to 15 cm height on 15 July (Cut2-15). The lowest dry matter (simulated grazing) was obtained from RCut1-5 (0.13 t ha−1) and the highest (0.86 t ha−1) was from ICut2-5. There was no significant difference (P 0.05) by either the watering regime or grazing. Seed weight was significantly (P
