The frequency dependences of the relaxation times of NMR spin echo signals of quadrupole nuclei 53Cr at te=τ and te=3τ in ferromagnetic semiconductor Cd0.985Ag0.015Cr2Se4 were investigated at temperature 4.2 K. It was shown that there are two kinds of the quadrupole nuclei 53Cr, which have quite different relaxation times. The existence of two kinds of the nuclei 53Cr was connected with doping of the cadmium selenochromite with Ag+ ions.
