A late sown winter wheat Marombi and experimental wheat 10.10.3 were grazed at three different times and compared to the ungrazed crop. Drymatter production available for grazing up to GS 30/31 was 1.48 t/ha for Marombi and 1.89 t/ha for 10.10.3. Early grazing had minimal or no impact on grain yield. Grazing in the early to mid vegetative stage increased grain yield of 10.10.3 by 0.36 t/ha or 5 %. However there was a yield reduction (0.48 t/ha or 8%) by grazing the Marombi. Given the limited number of samples taken, the variation in yield may not be different from the no grazing treatment. The change in stubble mass was less than anticipated, with a decline of up to 13%.
