Targeting maximum yields of irrigated wheat in southern NSW locations
Aims

To examine targeting maximum yields of irrigated wheat in southern NSW.

Key messages
  • Correct varietal selection and optimal agronomic management can result in irrigated wheat yields of over 10 t/ha.
  • LongReach CobraA, LongReach TrojanA and BeckomA were the highest yielding varieties.
  • Delaying nitrogen fertiliser application by applying the greatest amount at booting was shown to improve grain protein concentration and reduce lodging compared with applying more nitrogen at sowing.
  • A plant population of 120 plants/m2 was shown to yield more than higher plant populations whilst also minimising lodging.
