Probably it originated in southwestern Asia. It is best grown in soils well supplied with organic matter and in areas with medium to high relative humidity. Asian, short day cultivars require photoperiods of 12-14 hours to flower, while European, longday culktivars need at least 14 hours. Yields vary from 10 t/ha in Asia to 35 t/ha for summer crops in Europe and the United States.
