Three year evaluation of liquid and granule nutrition packages at Tuckey locations

To establish which of the following components has the greater effect on yield: liquid, granular or combined liquid/granular forms of fertiliser nitrogen, phosphorus and trace elements, and in-furrow fungicide.

Key messages
  • Across three years addition of trace elements and fluid fungicide in-furrow did not provide increases in emergence, tillering or final yield - although this contradicts what other farmers have reported.
  • Liquid N at sowing can improve crop emergence and early vigour, especially under dry conditions .
  • Full liquid systems did not provide a profit benefit (due to higher input costs) even where they did provide increased yield which was not in all years.
  • Recommendation most likely to provide higher returns for this area will be an in-furrow fertiliser system that incorporates some elements of liquid nitrogen and phosphorus fertiliser ,trace elements, fungicides and granular phosphorus and nitrogen fertiliser.
