The PHENIX experiment at RHIC measured the omega-meson production in the range of pT from 2.5 GeV/c to 9.5 GeV/c in p+p and d+Au collision systems at sqrt{ s_{ NN}}=200 GeV. We present the consistent results of two independent measurements in decay channels omega-->pi^{ 0}pi^{ +}pi^{ -}$ and omega-->pi^{ 0}gamma. The omega/pi^{ 0} ratio was found to be 0.90+/-0.06. The Nuclear Modification Factor R_{ dA} is 1.3+/-0.2 both in the Minimum Biased and (0%-20%) central event samples. The mass of the omega-meson was measured to be consistent with the PDG value within the errors of the measurement. We also measured the K_{ S}^{ 0}-meson production in K_{ S}^{ 0}-->pi^{ 0}pi^{ 0} in the same collision systems.
