International audience. The aim of this work was to evaluate the productive response of the tannia in function of different sizes of seed-rhizomes. The experimental design was randomized block with three types of seed-rhizomes (cormel, cormel 1 and cormel 2) and seven replicates. The experimental plot consisted of 16 plants, whereas evaluated the eight central plants. It was evaluated the following characteristics: total fresh weight, net production and commercial production. It was verified that the total, net, cormel and of the cormel 1 production was greater when using the cormel rhizome as seed. However, the commercial production of the cormel was equal to the cormel 1. We recommend growing Xanthosoma mafaffa Schott using as seed cormel propagules by a larger production and for not being marketable.
