In the present work we calculate the allowed $\beta^-$-decay half-lives ofnuclei with $Z = 20 -30$ and N $\leq$ 50 systematically under the framework ofthe nuclear shell model. A recent study shows that some nuclei in this regionbelong to the island of inversion. We perform calculation for $fp$ shell nucleiusing KB3G effective interaction. In the case of Ni, Cu, and Zn, we used JUN45effective interaction. Theoretical results of $Q$ values, half-lives,excitation energies, log$ft$ values, and branching fractions are discussed andcompared with the experimental data. In the Ni region, we also compared ourcalculated results with recent experimental data [Z. Y. Xu {\it et al.},\emph{Phys. Rev. Lett.} \textbf{113}, 032505, 2014]. Present results agree withthe experimental data of half-lives in comparison to QRPA.
