CSIRO Long Coleoptile Sowing Depth x Genotype; N placement x Rate x Sowing Depth and Seed Size x Sowing Depth Trial

Collaborating with CSIRO, funded by Ag Grow Agronomy and CSIRO.

Deep sowing (up to 15cm) to establish crops into stored summer soil moisture has the potential to aid successful early crop establishment in warm soils. Newer varieties being developed, with long coleoptiles, have the potential to overcome the limitations of sowing depth that current varieties with short coleoptiles have (limit approximately 4cm).

In 2025 there will be 2 experiments:

  1. A core experiment – which is also undertaken across Australia using the same 6 common wheat genotypes from a common seed source. Involves 6 genotypes by 2 sowing depths (4cm and 10cm).
  2. A nitrogen placement by rate and sowing depth experiment – involves 3 genotypes x 2 fertiliser rates (safe and unsafe MAP rate) x 2 fertiliser placements (with the seed and above the seed) and 2 x sowing depths (4cm and 10cm).
