Amorphophallus paeoniifolius (Dennst. Nicolson), syn. A. campanulatus (Roxb.) BL. exDence (also elephant foot yam) is largely cultivated in the Philippines, Java, Indonesia, Sumatra, Malaysia, Bangladesh, India and China. In India, it is cultivated in the states of Andhra Pradesh, West Bengal, Gujarat, Kerala, Tamil Nadu, Maharashtra, Uttar Pradesh and Jarkhand. Sree Padma, Gajendra, Sree Athira (a hybrid), Bidhan Kusum and NDA-9 are some of the high yielding Amorphophallus varieties released for cultivation. The corm production potential of this crop is 50-80 t ha-1 and net economic return is about 2000 – 3000 US$ per ha. Plant growth and corm yield is influenced by the size of planting material (corms/cormels/corm pieces), plant spacing, nutrient management and water availability. Nevertheless, the production aspect of this crop is less understood as scanty research has been conducted in this crop. The available literature on growth and productivity of elephant foot yam is briefly described in this article.
