Assessing agronominc options for managing wheat on water repellent soils locations
Aims
  • To assess the impact of sowing times, seeding rate and wetting agents on wheat establishment and productivitey on water repellent soil and determine whether there is a positive interaction between the agronomic options tested. 
  • This trial was conducted at four locations acros the wheatbelt. The results are only for the Binnu site. 
Key messages
  • Seeding rate had a bigger impact on wheat establishment than soil wetting agents
  • High seeding rates on soils with low yield potential were sometimes a disadvantage; optimal seeding rates would need to account for yield potential as well as the degress of soil water repellence.
  • Delaying sowing providing an opprtunity to get a knockdown of weeds was important on water repellent soils where staggered weed germination and reduced herbicide activity, reduces the efficacy of in-crop and pre-emergent applications.
