The aim of this work was to assess a few biometric characteristics, yield and gross revenue of four taro clones cultivated in a Dystrorthox soil, clay texture. Macaquinho, Japonês, Chinês and Cascudo clones were studied, in a randomized block experimental design with six replications. Plants of Chinês and Cascudo taro showed the highest heights and fresh leaf mass. For the values of diameter and length of RM, diameter of commercial RF and of length of noncommercial RF, percentages of dried leaf mass, RM and RF significant influences of clones were detected. These four studied clones showed similar statistics for yield values (t ha-1) of fresh mass of corm (from 4.22 for 'Japonês' up to 4.49 for 'Macaquinho') and of cormels (from 14.84 for 'Macaquinho' up to 16.83 for 'Cascudo') and noncommercial cormels (variation from 4.44 for 'Macaquinho' up to 5.19 for 'Chinês'). Observing average estimates regarding to gross revenue, it was concluded that cultivation of Cascudo taro was the best, which was R$ 192.00, R$ 2,136.00 and R$ 2,388.00 over revenues for 'Japonês', 'Chinês' and 'Macaquinho', respectively.
