ABSTRACT:

Amorphophallus paeoniifolius is a widely grown food crop in the Indian subcontinent, Southeast Asia and China. The crop is grown by planting corms or corm segments, with whole corms of 500–750 g weight the preferred material. A shortage of planting material of this size is a constraint for commercial cultivation and increasing maximum food production. Research is reported on methods of producing corms of this size from cormels and planting setts. Results differ regionally and optimum combinations in plant spacing and fertilization have been developed to account for varying soil and climatic conditions.
