Barley time of sowing and depth locations
Aims

To compare the competing demands of timeliness of sowing versus sowing to maximise establishment (deep versus dry sowing, or waiting for adequate rainfall later in the season).

Key messages
  • LaTrobe, GrangeR, and Skipper had reduced emergence from deeper sowing under both dry and wet sowing conditions. 
  • Varieties differed in their sensitivity to sowing time; variety choice and sowing time influenced grain yield and quality more than sowing depth.
  • LaTrobe and Fathom were the highest yielding varieties across both sowing dates.
  • Commander and Skipper were the only varieties to suffer a yield penalty from early dry sowing.
  • GrangeR yielded similar to Commander at earlier sowing but less when delayed.
  • Screenings were greater than 7% and retention less than 70% in LaTrobe across both sowing times, and in Commander and GrangeR at earlier sowing only.
  • Skipper was the only variety to achieve malt specifications across both sowing times.
