ABSTRACT
Piper hispidum is a pioneer species belonging to the family Piperaceae, with relevance in popular medicine and in obtaining essential oil. As other species of this family, there is little information about cultivation techniques. The aim of this work was to evaluate the propagation through cutting from the Piper hispidum according to the type of substrate and cutting technique in Manaus, Amazonas, Brazil. The trial experiment was conducted at the Embrapa Western Amazon. The design was completely randomized factorial 3 x 5, with three replications of 12 cuttings with types of cuttings (apical, median and basal) and substrates (washed sand, commercial substrate, soil + poultry manure, soil + guarana shell and coconut fiber). After 60 days, the following characteristics were evaluated: rooting (%), number of shoots, length of the largest sprouting (cm), number of leaves, length of the longest root (cm), root dry weight (g) and dry weight of shoots (g). An analysis of variance was performed by the F test at 5% probability and for the averages` comparison the Tukey test was done at 5% level of probability. It is recommended to employ apical and basal cuttings, respectively. There was interaction between the factors and substrate types of cuttings only for the variable number of sprouts. These two substrates, washed sand and commercial substrate, are suggested for higher percentages of rooting with 81,56% and 81,33 %, respectively. The rooting was higher in the apical cuttings (85,67 %) and basal ones (74,47 % ). However, for this species, the substrates soil + poultry manure and/or soil + guaraná shell were most indicated when the goal was to obtain high-quality cuttings.
