Defining guidelines for canopy management in wheat, May sown MacKellar locations
Aims
  • To determine the interaction of nitrogen timing and dose with plant population in terms of yield, crop structure, predisposition to lodging and quality in the high rainfall zone.
  • To determine the influence of nitrogen applied at stem elongation versus up front nitrogen on soil moisture content and dry matter production.
Key messages

Late sown Mitre (July 4) produced yields in the range of 0.6 – 2.16 t/ha following Canola stubble. With soil nitrogen reserves of approximately 30kg/ha N (0-10cm) recorded pre sowing, applied nitrogen was detrimental in this trial, with 50 kg/ha N reducing yield by 0.09t/ha and 100kg/ha N reducing yield by 0.23 t/ha. These figures disguise more detrimental yield reductions with seedbed nitrogen applications and no effect from stem elongation timings applied at GS31-39.
