The widths of the strong decays $Z_c^{+}(3900)\to J/\psi \pi^{+}$ and$Z_c^{+}(3900)\to \eta_{c} \rho^{+}$ are calculated. To this end, the mass anddecay constant of the exotic $Z_c^{+}(3900)$ state are computed by means of atwo-point sum rule. The obtained results are then used to calculate the strongcouplings $g_{Z_{c}J/\psi \pi }$ and $g_{Z_{c}\eta_{c} \rho }$ employing QCDsum rules on the light-cone supplied by a technique of the soft-mesonapproximation. We compare our predictions on the mass and decay widths withavailable experimental data and other theoretical results.
