What sort of crop canopy did we need in May sown MacKellar wheat in 2007 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

May 4th sown Mackellar wheat produced yields in the range of 4.74 – 5.99 t/ha following canola stubble. With high soil nitrogen reserves (176 kg/ha N, 0‐90cm) recorded 2 days pre sowing, there was a small but significant response to applied nitrogen (0.43 t/ha at 50kg/ha N & 0.58 t/ha at 100kg/ha N). There was a significant advantage to nitrogen timed during stem elongation (GS30‐39) over nitrogen applied in the seedbed. This advantage was evident in both single and split applications between which there was
no difference.
