Summer rain and stubble management locations

To measure the interaction between stubble management and soil moisture on:

  1. the retention of soil water accumulated outside the growing season, and
  2. the value of stored water to crop physiological traits and yield.
Key messages
  • Wheat yield increased from 2.6 t/ha in controls to 3.2 t/ha in plots receiving the equivalent of summer rainfall decile 5 (50mm) or decile 9 (100mm) in a single event in February.
  • Stubble treatments (bare ground control, standing 2 t stubble/ha, flat 2 t stubble/ha, flat 5 t stubble/ha) did not affect the dynamics of soil water nor grain yield.
