The objective of this study was to evaluate different proportions of the regional substratum based on the decomposed babassu stem on the vegetative propagation of the 'Wonderful' pomegranate. The experiment was carried out from April to June of 2017, in a greenhouse with 50% luminosity. Woody stakes of pomegranate were planted approximately 20 cm in length and the diameter ranged from 2.0 to 4.0 mm. The experiment was conducted in a completely randomized design with 6 treatments, 4 replicates, 2 plants per experimental plot. The treatments consisted of 6 different substrate formulations: : i) control (100% soil); ii) 20% decomposed babassu stem + 80% soil and sand mixture (1: 1); iii) 40% decomposed babassu stem + 60% soil and sand mixture (1: ); iv) 60% decomposed babassu stem + 40% soil and sand mixture (1: 1); v) 80% decomposed babassu stem + 20% soil and sand mixture (1: 1); vi) 100% decomposed babassu stem. It was verified that the use of different proportions of decomposed babassu stem affected the vegetative propagation of the 'Wonderful' pomegranate, with positive effects on rooting mainly root length. For best yields, the substrate is recommended in the proportion of 80% of the babaçu decomposed stem with 20% soil.
