By the replies here , it seems grass seed might be the best option. They are giving a dry week , so if rapedidnt germinate quickly this late in the year , it would be a waste of money for a poor return.
A friend sowed it in July one year , and got most of the winter out of it grazing with weanlings. However , it looked like the scene of the battle of the Somme , and he couldn’t plough it until June the next year , so it took up the field for just 12 months. Hardly a “catch crop “.
I have silage to cut still, but not expecting it to be a bumper crop. I wouldn’t be too bad for feed if it’s ok , and I trim down stock , and the winter is 4 1/2 or 5 months long , not 6 1/2 months.
