The effect of sowing rate on the performance of H45 and Diamondbird wheat locations
Aims

To provide further information regarding sowing rates and optimum plant densities.

Key messages
  • Plant population is poorly correlated with sowing rate. Farmers should focus more on plant populations rather than just sowing rate.
  • High plant populations increased yield without affecting grain quality in these two trials.
  • Dryland wheat farmers in the Parkes and Forbes areas should target a plant population of 100-120 plants / m2.
  • Sowing rates should vary depending on seed size, germination and sowing conditions to achieve the target plant density.
