  We study the upper critical field of the A and B phases in the triplet
superconductor PrOs_{4}Sb_{12} within the p+h-wave superconductivity proposed
recently for this material. The present result is compared with H_{c2}(t) and
H*(t), the boundary between the A and B phase in PrOs_{4}Sb_{12}, reported
earlier and with more recent data of H$_{c2}(t)$ for the single phase crystal.
We find H_{c2}(t)'s for both the two phase crystal and the single phase crystal
are described by the model for the A phase. From this fitting one can deduce
the Fermi velocity as v=2.5 x 10^6 cm/s. On the other hand H_{c2}(t) for the B
phase is found to be somewhat smaller than H*(t), which is rather puzzling.
