The magnetic properties of RCo_{2}Si_{2} (R = Nd, Tb, Dy) compounds were studied by measuring the high-field magnetization in magnetic fields up to 140 kOe and over the temperature range 4.2-45 K. The magnetic field induces in NdCo_{2}Si_{2} three metamagnetic phase transitions and two transitions in TbCo_{2}Si_{2} and DyCo_{2}Si_{2} compounds.
