Barley phenology and optimum time of sowing locations
Aims

To determine the best sowing window to achieve optimal flowering periods and maximise yield performance in new barley varieties.

Key messages
  • Fathom, La Trobe, Spartacus CL, Rosalind, Hindmarsh and Compass are consistently yielding the highest in the Mallee and Wimmera NVT.
  • Compass is very quick to mature and performs better in terms of yield and management at a later sowing time.
  • Yields from April and early May sowing flowered too early and were affected by frost events. The June sowing had the highest average yields, but was sown later than ideal for the region.
  • Mid to late maturing varieties Urambie and RGT Planet were least affected by frost when sown early May and yielded the highest.
