Abstract: The production of $\rm K^*(892)^0$ and $\phi(1020)$ resonances has been measured in p-Pb collisions at $\sqrt{s_{NN}}$ = 8.16 TeV using the ALICE detector. Resonances are reconstructed via their hadronic decay channels in the rapidity interval $0.5 < y < 0$ and the transverse momentum spectra are measured for various multiplicity classes up to $p_T$= 20 GeV/$c$ for $K^*(892)^0$ and $p_T$ = 16 GeV/$c$ for$\phi(1020)$ . The $p_T$-integrated yields and mean transverse momenta are reported and compared with previous results in pp, p-Pb and Pb-Pb collisions. The $x_T$ scaling for $\rm K^*(892)^0$ and $\phi(1020)$ resonance production is newly tested in p-Pb collisions and found to hold in the high-$p_T$ region at LHC energies. The nuclear modification factors ($R_{\rm{pPb}}$) as a function of $p_T$ for $\rm K^*(892)^0$ and $\phi(1020)$ at $\sqrt{s_{NN}}$= 8.16 TeV are presented along with the new $R_{\rm{pPb}}$ measurements of $\rm K^{*0}$, $\phi$ , $\Xi $, and $\Omega$ at $\sqrt{s_{NN}}$= 5.02 TeV. At intermediate $p_T$(2-8 GeV/$c$), $R_{\rm{pPb}}$ of $\Xi $, $\Omega$, show a Cronin-like enhancement, while $\rm K^{*0}$ and $\phi$ show no or little nuclear modification. At high $p_T >$( 8 GeV/$c$), the values of all hadrons are consistent with unity within uncertainties. The $R_{\rm{pPb}}$ of $\rm K^*(892)^0$ and $\phi(1020)$ at $\sqrt{s_{NN}}$= 8.16 and 5.02 TeV show no significant energy dependence.
