An experiment was carried out in Nova Friburgo, located in the mountain region of Rio de Janeiro State, to evaluate the effect of poultry litter doses on the performance of organically grown taro, under no-tillage. The soil of the area was a Haplic Cambisol. Black oat was previously cultivated in the experimental area. The experimental design was of randomized blocks, with four replications. The treatments consisted of 0; 50;100 and 200 kg N ha-1 of poultry litter, applied 120 days after planting. The use of poultry litter promoted a significant increase in taro yield, with a maximum value corresponding to 130 kg ha-1 of N rate of. It also increased the N content of the taro rhizomes.
