Spring Lupin in Association with Cereals for Grain Production

Spring-sown lupin in association with cereals (oats, barley, rye) for grain production in Brittany and Pays de la Loire. Compares weed control, yield impact, maturity alignment, harvest ease, and valorisation. Oats show 60% average yield reduction; barley 37%. Lupin yield stable or reduced in most trials. Protein content averages 30.2%. Oats and barley tested at 20% of pure crop rate. Triticale and narrow-leaved lupin (blue lupin) compared. Results from 13 trials.
