It did about .6/acre. It set our combine on fire so a neighbour ended up doing it with a straw walker. Blackgrass control was poor. Won’t be growing it again I would rather do stewardship however a mix of osr, oats and beans are enough for our break crops.
We grow rape and beans too. On heavy land we can grow long runs of cereals though and they are always more reliable than beans, osr and make the other crap like linseed or peas look completely pointless (I’ve tried)
Farmers arguing about the size of farm being an issue is ridiculous. There is god awful small livestock farms in the same way there is terribly run large farms and vice versa in all businesses and sectors.
