Barley response to N applied at sowing locations
Aims

To assess the response of six barley varieties treated with five different N rates at sowing.

Key messages
  • When the maximum rate of nitrogen (N) was applied, La Trobe achieved malt grade and the greatest profitability.
  • Fathom was the most N efficient variety, converting the most supplied nitrogen to grain, whereas Compass and Commander were the least responsive.
  • The highest rate of N (120kg N/ha) was the most profitable for all varieties in a Decile 10 growing season
