Grain legumes such as pea, faba bean and lupin produce high-quality protein for food and feed. However, they are only grown on 1.5% of European arable land due to the belief that their yield is highly variable. Scientists Reckling et al. show that grain legume yields are actually as stable as other spring crops when evaluated in long-term experiments and with an appropriate indicator. These novel findings could overcome the current negative perception of grain legume cultivation and stimulate initiatives to improve the crops agronomy.
