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.
