Summer rain, stubble management and nitrogen locations
Aims

To measure the interaction between stubble management, frequency of rainfall events and fertiliser nitrogen on:

  • the retention of soil water accumulated outside the growing season.
  • the value of stored water to crop physiological traits and yield.
Key messages
  • The presence of stubble did not increase stored soil moisture, regardless of the size and number of irrigation events.
  • In 2010 additional soil moisture at sowing did not generally increase final grain yield.
  • Additional soil moisture can increase crop demand and response to nitrogen.
