The transverse and longitudinal gluon propagators in the Landau gauge arestudied in the two-color lattice QCD at nonzero quark chemical potential$\mu_q$. Parameterization of the momentum dependence of the propagators isprovided for all values of chemical potential under study. We find that thelongitudinal propagator is infrared suppressed at nonzero $\mu_q$ withsuppression increasing with increasing $\mu_q$. The transverse propagatordependence on $\mu_q$ was found to be opposite: it is enhanced at large$\mu_q$. It is found, respectively, that the electric screening mass isincreasing while the magnetic screening mass is decreasing with increasing$\mu_q$. Nice agreement between the electric screening mass computed from thelongitudinal propagator and the Debye mass computed earlier from the singletstatic quark-antiquark potential was found. We discuss how the dependence ofthe propagators on the chemical potential correlates with the respectivedependence of the string tension. Additionally, we consider the differencebetween two propagators as a function of the momentum and make interestingobservations.
