Arracacha production has been markedly increasing in some regions of Brazil, with a indreasing demand in the most important consuming centers. A field experiment was conducted with the objective of evaluating the development of this species in the State of Rio de Janeiro. Three levels of N, P and K were tested in completely randomized blocks design with four repetitions in a factorial scheme. Shoot, corm and root samples were collected four times along the plant cycle. The highest shoot dry weight accumulation was recorded at 180 days, for corm and roots at 300 days after planting. No Significant effects of phosphorus and potassium levels were observed and the highest production was reached with the level of 60 kg.ha-1 of N.
