Producing spring lupin in association for grain harvest in organic farming

Spring-sown lupin associations with cereals in organic farming in Brittany and the Pays de la Loire. Evaluates weed control, yield, harvest timing, and valorisation of white, blue, and yellow lupin with oats and barley. Focus on optimal cereal pairing, yield outcomes, and weed biomass at flowering. Results from 2015–2016 trials show white lupin yields up to 42.9 q/ha in Brittany, blue lupin up to 32.2 q/ha, with protein content at 33.6% (white) and 25.4% (blue).
