I'm not aware of any real allelopathy in sunflowers. I've known commercial
growers to raise sunflowers on significant acreage (60 -200) and follow that
with soybeans or corn the next season with no impact on the following crop.
It could be that the reason that the previous writer observed problems with
germination of other seeds had nothing to do with allelopathy. I'm sure that
sunflowers do not produce juglone, the allelopathic compound in black
walnut.

>Interesting discussion. I had been planning on trialing a small plot of
giant sunflowers (25 x 25)to dry and sell to bird enthusiasts in the fall,
maybe at 50 cents per head. Does anyone know if the sunflowers' alleopathic
(sp?) effect will continue into next season's crop rotation in that patch?
If so I will have to rethink this idea. Thanks.
