Coloring ranges from black with light spots to white or light cream. Weight of 100 seeds 145-200 g. Very polymorphous species. Color variability is typical.


Wild plant grows in Mediterranean. First sowing in Russia was in 1903. Cultivated as far north as 58? of northern latitude. Grown as a green manure as far north as 60° latitude. Planting occurs in Ukraine, Belarussia, and the Baltic States; in Russia mainly in Nechernozem zone.


Plant requires long days. More resistant than other lupins to cold; in the beginning of vegetation, bear frost up to -7° C. Water-resistant plant. Prefers light loamy and sandy-loam soil. Optimal pH 5-6. Vegetation period depends on methods, year and place of cultivation (72-170 days). Mainly self-pollinated.

Economic value.

Feed crop. Seeds contain 32-34% protein and up to 2% bitter alkaloids. Productivity of forage is 25-40 ton per hectare, seeds up to 2.7 ton per hectare. Used also as medicinal plant, source of vitamines, insecticide, and green manure. Varieties: Benjakonskij 484, Brjanskij 123, Nemchinovskij, Danko, Ladnyi, Rozovyi 399, Uzkolistnyi 109.
