Improving profitability of wheat in fallow / pasture through better agronomy locations
Aims

This trial is conducted to investigate the value of nitrogen on the profitability of new wheat varieties in early and late sowings in fallow/wheat system at Wongan Hills

Key messages
  • Varieties in this trial did not show a response to extra applied nitrogen at this site which was in pasture for the previous 3 years. Possible reasons are low rainfall and plants being water limited and/or sufficient background levels of nitrogen available for the crop in this soil type. 
  • In this season results showed a benefit in seeding early, providing greater growing season and therefore yield benefit, averaging 210 kg/ha higher.
