Lucerne in the crop rotation locations
Aims

To answer some key questions about lucerne in the crop rotation:

  • What is the impact of the lucerne phase on subsequent crops regarding yield, quality, soil moisture and nitrogen?
  • What is the best time to remove lucerne - spring or autumn?
  • What is the best method of removing lucerne?
  • What is the best crop rotation following lucerne?
  • What are the management implications of these insights from a farming system?
     
Key messages
  • Autumn removal of lucerne significantly decreased subsequent winter crop yields compared to spring removal of lucerne.
  • Crops sown after spring removal of lucerne yielded the same as the crops grown in a continuous crop rotation.
  • The crop yield penalty from autumn removal only lasts for one year.
  • Apart from Grazon, all other herbicide treatments gave unacceptable lucerne control.
  • Cultivation in combination with other herbicides will increase lucerne control by  20 to 30%.
