Early sowing of wheat locations
Aims

To assess the impact of time of sowing (TOS) on a range of wheat variety maturity classes (winter wheat, slow and mid spring maturing varieties) and to measure the impact of plant density and the presence of weeds (simulated with tame oats) on these varieties.

Key messages
  1. Winter wheat cultivars Wedgetail and Rosella sown on 1 April were higher yielding than LRPB Scout sown on 6 May.
  2. Reducing plant density to 50 plants/ m² did not reduce the ability of winter wheats to compete with a simulated weed population (tame oats) when sown on 1 April
  3. Winter wheat sown early produced more dry matter for grazing than spring wheats sown in May.
