Grain & Graze 3 - Grazing crops and frost locations
Aims

To assess the impact of (and interaction between) grazing and frost damage on the grain yield and quality of a range of winter and spring cereal varieties sown at two times of sowing.

Internal notes

In these experiments, cereal crops were sown 2 to 4 weeks earlier than standard district practise. This significantly increased the amount of crop biomass available for grazing in early to mid-winter. As an example, the increase in available biomass at Wickepin from early sowing was over 600% (599 vs 95 kg/ha). If additional livestock production is a major priority from grazing crops, early sowing is a must.
