Vetch termination 2014–2012 end use treatment locations
Aims

To determine how the management of a vetch crop (termination timing and end-use) influences the yield and quality of a following wheat crop grown for two consecutive years.

Key messages
  1. When vetch is establised in March and is terminated 'early' (three to four months later, in June, July), soil water will be conserved for the subsequent wheat crop; the risk of haying off due to high nitrogen will be lower than if the vetch were terminated 'later' (August, September),
  2. Vetch biomass production of approximately 2t/ha is unlikely to cause a subsequent wheat crop to hay off given dry seasonal conditions. 
  3. Residual nitrogen from vetch brown manure can carry over for two years and influence cereal crop growth, but the conservation of soil water is more critical in seasons of Decile 2 or lower.
