Grazing crops to maintain yield locations
Aims

To investigate the drivers for yield loss under grazing with a view to make grazing crops less risky.

Key messages
  • Grazing did not change grain yield in 2015 or 2016. Variety selection was the most important factor for final yield, particularly with the soft finish in 2016.
  • Grazing slows crop maturity by one to two weeks, which meant Revenue (long season variety) was still booting during the October heat wave in 2015. In 2016, grazing lengthened the growing season for Bolac (mid-season variety) with a resulting 0.54 t/ha (NS) yield increase.
  • To graze without yield loss, it’s important to start planning from the beginning of the season, e.g. early sowing of long season varieties.
