The objective of this work was to evaluate the efficiency of three organic substrates, carbonised rice hull, dry and green coir dust, and two fertilizers, Vitasolo® and earthworm humus, in the acclimatization of plantlets of Heliconia psittacorum L., obtained from micropropagation. After 75 days, the height of the plants, diameter of pseudo-stem, number of leaves and area of the third leaf were evaluated. The rice hull was more efficient than the coir dust (dry or green); the green coir dust was more efficient than dry coir dust; and the humus was more efficient than Vitasolo®.
