The present experiment tested different vermiculite (V) proportions and carbonized rice husks (CRH) over passion fruit (Passiflora edulis Sims f. flavicarpa Deg.) cutting propagation. The cuttings had two leaves treated with 1000 mg.L-1 of indolebutyric acid for 10 seconds. The experiment was conducted under greenhouse conditions with an intermittent micro spraying system. The experimental design was randomized in blocks with 5 different treatments (100% V ; 75% V: 25% CRH; 50% V: 50% CRH; 25% V: 75% CRH; e 100% CRH), 4 replicas and 15 cuttings per experimental unit. Salinity, pH, bulk density, and moisture release curve of growing average were evaluated. In addition, cuttings were evaluated on survival; roots number, branches and leaves; roots length and dry matter and branches. The obtained data indicate that 50% V: 50% CRH and 25% V: 75% CRH produced the best results for passion fruit cutting propagation.
