Barley agronomy - maximising yield potential and quality locations
Aims
  • To observe how such treatments affect yield and grain quality at low, medium and high levels.
Key messages
  • In the 2012 season, barley variety and nitrogen rate had a greater impact on yield and grain quality than plant population
  • There was no significant increase in grain yield from increasing the N rate beyond a 5t/ha yield potential in this season. Any additional applications did not increase the yield enough to justify the cost of the fertiliser.
  • All varieties displayed significant positive responses to the increasing rates of N
  • The 62 kg N/ha rate (for 5t/ha crop) gave us the maximum grain yield return.
  • Optimum plant populations for grain yield were 200plants/m2. In 2012 although increasing plant densities tended to reduce grain quality but they still made malting quality.
