The frequency dependences of the relaxation times of NMR spin echo signals of quadrupole nuclei ^{53}Cr at t_{e}=τ and t_{e}=3τ in ferromagnetic semiconductor Cd_{0.985}Ag_{0.015}Cr_{2}Se_{4} were investigated at temperature 4.2 K. It was shown that there are two kinds of the quadrupole nuclei ^{53}Cr, which have quite different relaxation times. The existence of two kinds of the nuclei ^{53}Cr was connected with doping of the cadmium selenochromite with Ag^{+} ions.
