  With only three flavors it is possible to account for various neutrino
oscillation experiments. The masses and mixing angles for three neutrinos can
be determined from the available experimental data on neutrino oscillation and
from the astrophysical arguments. We have shown here that such masses and
mixing angles which can explain atmospheric neutrino anomaly, LSND result and
the solar neutrino experimental data, can be reconciled with the R-parity
violating Supersymmetric Models through lepton number violating interactions.
We have estimated the order of magnitude for some lepton number violating
couplings. Our analysis indicates that the lepton number violation is likely to
be observed in near future experiments. From the data on neutrino oscillation
and the electric dipole moment of electron, under some circumstances it is
possible to obtain constraint on the complex phase of some supersymmetry
breaking parameters in R-parity violating Supersymmetric models.
