Weak current-induced baryonic form factors at zero recoil are evaluated inthe rest frame of the heavy parent baryon using the nonrelativistic quarkmodel. Contrary to previous similar work in the literature, our quark modelresults do satisfy the constraints imposed by heavy quark symmetry forheavy-heavy baryon transitions at the symmetric point $v\cdot v'=1$ and are inagreement with the predictions of the heavy quark effective theory forantitriplet-antitriplet heavy baryon form factors at zero recoil evaluated toorder $1/m_Q$. Furthermore, the quark model approach has the merit that it isapplicable to any heavy-heavy and heavy-light baryonic transitions at maximum$q^2$. Assuming a dipole $q^2$ behavior, we have applied the quark model formfactors to nonleptonic, semileptonic and weak radiative decays of the heavybaryons. It is emphasized that the flavor suppression factor occurring in manyheavy-light baryonic transitions, which is unfortunately overlooked in mostliterature, is very crucial towards an agreement between theory and experimentfor the semileptonic decay $\Lambda_c\to\Lambda e^+\nu_e$. Predictions for thedecay modes $\b,~\Lambda_c \to p\phi,~\Lambda_b\to\Lambda\gamma$,$\Xi_b\to\Xi\gamma$, and for the semileptonic decays of $\Lambda_b,~\Xi_{b,c}$and $\Omega_b$ are presented.  }Comment: Latex, 20 pages.
