Impact of grazing at different growth stages on dry matter, grain and stubble of two wheat varieties locations
Aims
  • To quantify the amount of high quality feed that can be grown before GS 30
  • To identify the difference growth patterns of two winter wheat varieties
  • To quantify the grain yield and stubble mass changes due to grazing
Key messages

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%.
