Minimising yield loss in grazed crops locations
Aims

To take a step back and look at how important rainfall and variety choice are in grazing crops to maintain grain yield.

Key messages
  • Grazing did not change grain yield or quality. Rather, moisture stress was more important in a dry finish
  • In a dry year, the ratio of grain yield to crop biomass at flowering is 0.40. In an average year it is around 0.55
  • Grazing slows crop maturity by one to two weeks, which meant Revenue (long season variety) was still booting during the October heat wave
