Kalanamak - promoted by Lord Budhha himself. Kalanamak is one of the finest quality scented rices. It derives its name from black husk (kala = black; the suffix ‘namak’ means salt). This variety is in cultivation since the Buddhist period (600 BC). It was quite popular in Himalayan Tarai of Kapilvastu, Nepal and eastern Uttar Pradesh, India; however, acreage under this variety declined sharply due to increased use of high yield varieties forcing it to near extinction.
