Setting up a new airseeder wondering what spacing is best. Planting canola, peas, beans, wheat and barley.

10" for higher weed competition & increase yield but have to go slower with high chemical loads. 12" happy medium. 15" to grow weeds & go broke but can use a shielded sprayer. IMO. I'm on 300mm and pretty happy with it but maybe would be better to go to 10".
Trials show the narrower the spacing and high seeding rates = higher yields & better weed competition.
What are you trying to achieve are you moving toward tramlines?

Looking controlled traffic, but not to sure if there is a real purpose on our property for it. We are putting on ag master splitter boots so would take it down to 10. few blokes around are using 9" with the 3" splitter.

World record on wheat yield was set using 6" spacing.......... just saying.
In our neck of the woods the narrower the better because of soil temps getting too high when the sun hits, so we need a quick canopy.

Go 9 or 10" splitters work good to keep chemical out of furrow from what I hear. As for tramlines think it should be put on the priority list. IMO. But your going to have a hard time sowing between the rows on 9" with splitters even with rtk & a side shift hitch.

At a recent herbicide resistance field day, one of the speakers from WA said that narrower spacings (<9" ) were best to out compete weeds. Add in the low cutting that goes with winddrow burning/chaff carts, and reside management is a non issue.

It made me think hard about where to go in the future.

we ave never ad a problem wit 7" on windrow burning yet do like the out competing weeds though that's why I figure 12"" with a 3" split so it brings it back to a 9"
