Broad beans have a long tradition of cultivation in Old World agriculture, being among the most ancient plants in cultivation and also among the easiest to grow. Along with lentils, peas, and chickpeas, they are believed to have become part of the eastern Mediterranean diet around 6000 BC or earlier. They are still often grown as a cover crop to prevent erosion, because they can overwinter and because as a legume, they fix nitrogen in the soil. These commonly cultivated plants can be attacked by fungal diseases, such as rust (Uromyces viciae-fabae) and chocolate spot (Botrytis fabae). They are also attacked by the black bean aphid (Aphis fabae).
The broad bean has high plant hardiness; it can withstand rough climates, and in this case, cold ones. Unlike most legumes, the broad bean can be grown in soils with high salinity, as well as in clay soil. However, it does prefer to grow in rich loams.
