To quantify the drymatter potential of seven long season cereal crops before stem elongation is reached and to determine the impact on grain yield if heavy grazing occurs at GS31.
Key messages
Intensive grazing at GS 30 – GS 31 (start of stem elongation) reduced grain yield compared to no grazing by an average of 37%. The greatest yield loss of 57% occurred with Monstress triticale and the lowest yield loss occurred with Amarok wheat (18%). Up to 2.1 t/ha of drymatter was available for grazing before stem elongation was reached. Yerong barley yielded the greatest drymatter pre grazing, with Brennan wheat the lowest drymatter yielding at 1.5 t/ha.
