Edible Uses
Edible Parts: Seed
Edible Uses:
Seed - cooked[177]. Used as a protein-rich vegetable or savoury dish in any of the ways that cooked beans are used, they can also be roasted or ground into a powder. If the seed is bitter this is due to the presence of toxic alkaloids and the seed should be thoroughly leached before being cooked. The seeds of low-alkaloid varieties is used in making 'tempeh'[183]. The seed is rich in protein, though it is deficient in the amino-acid methionine[240]. The protein has a high digestibility (90%) and biological value(53%)[240].

Cultivation details
An easily grown plant, it succeeds in any moderately good soil[1]. Requires a sunny position[200]. Prefers a light acid soil[50] but tolerates adverse conditions. Dislikes limey soils[50]. Sometimes cultivated for its edible seeds, there are some named varieties that are low in the bitter toxic alkaloids. 'Uniwhite' is a low-alkaloid variety with a permeable seed coat. It has reduced pod-shattering[183] and so is easier to harvest mechanically. The blue lupin is a good companion plant for most vegetables[201]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[200]. When removing plant remains at the end of the growing season, it is best to only remove the aerial parts of the plant, leaving the roots in the ground to decay and release their nitrogen.
