Lupin / triticle for wholecrop works very well organically (neither crop suffers much pest or disease) and the competitive nature of the mixture can help with weed suppression.Can lupins be grown organically? We grew vetch with peas years ago; but I’d like to try Lupins.
Harvesting mature lupins with a combine would be OK if the weed control was OK, but often it isn't and there's too much green junk in the field.
Some growers accept this, since the sheer cost of organic soya makes organic lupins worth it - even if it means low yields from combining a field that is 50% fat hen....
The fact that you can use lupins as a direct replacement for soya makes them a very attractive proposition when organic soya meal is weighing in at £700 per tonne.
