I would like to try and mix some either redclover or lucerne with my winter cereals-drilling this autumn, preferrably with winter barley. Idea is to have a double-crop, either combine the barley and chop all straw if the legume is not so much or stripper header off the barley and mow and bale the straw with the legume in it if the legume is too thick for combining the cereal with cutterbar. Then let the legume grow for fattening lambs on it in late summer/autumn and disc-drill the next winter cereal (wheat) into it, maybe let some sheep lightly graze it further on in the autumn and then knock back the legume in the spring with a herbicide. Everything direct-drilled of course. Can anybody give me advice on what to take care about, seed rates and most scary for me : which herbicide options do I have this autumn / next spring with a clover or lucerne growing in the cereal crop ?? And what herbicide and rate is needed if I have to suppress (not kill !) the legume next spring if neccessary ?
