The experiment was carried out with 2x1 m spacing, in an Oxisol with sandy clay loam texture. A randomized complete block design was used, following a 2x9x6 factorial arrangement, with two propagation methods (seeds and cuttings), nine sampling spacings (0.15, 0.30, 0.45, 0.60, 0.75, and 0.90 m between rows,  and 0.15, 0.30, and 0.45 between plants within rows), six soil depths (0.10?0.20, 0.20?0.30, 0.30?0.40, 0.40?0.50, and 0.50?0.60 m), and six replicates. Soil cores (27 cm3) with roots were taken from 12 experimental units, 146 months after planting. The surface area of the root system and root diameter, length, and volume were assessed for 13 years and, then, correlated with grain yield. The highest fine root concentration occurred at the superficial soil layers. The variables used to characterize the root system did not differ between propagation methods. Moreover, no differences were observed for net photosynthetic CO2 assimilation rate, stomatal conductance, internal CO2 concentrations, and instantaneous water‑use efficiency in the leaves. Cutting‑propagated plants were more productive than seed‑propagated ones.  aVegetative propagation  aCoffea Canephora  aPropagação vegetativa  aComprimento de raiz  aDiâmetro de raiz  aRoot diameter  aVolume de raiz1 aCOVRE, A.
