Abstract From {sup 29}Si NMR study, we present evidence for spatially inhomogeneous development of antiferromagnetic (AF) ordering below T{sub o}=17.5 K in URu{sub 2}Si {sub 2}. In the pressure range between 3.0 and 8.3kbar, we have observed the {sup 29}Si NMR lines arising from the AF region as well as the previously observed {sup 29}Si NMR line which correspond to the nonmagnetic region in the sample. The AF volume fraction is enhanced by applied pressure, whereas the magnitude of internal field at the Si site remains constant (910Oe) up to 8.3kbar. In the AF region, the ordered moment is about an order of magnitude larger than 0.03 {mu}{sub B}/U.
