Let ω and ν be radial weights on the unit disc of the complex plane, and denote σ=ωp′ν−pp′ and ωx=∫01sxω(s)ds for all 1≤x<∞. Consider the one-weight inequality \begin{equation}\label{ab1} \|P_\omega(f)\|_{L^p_\nu}\le C\|f\|_{L^p_\nu},\quad 1<p<\infty,\tag{\dag} \end{equation} for the Bergman projection Pω induced by ω. It is shown that the moment condition Dp(ω,ν)=n∈N∪{0}supω2n+1(νnp+1)p1(σnp′+1)p′1<∞ is necessary for \eqref{ab1} to hold. Further, Dp(ω,ν)<∞ is also sufficient for \eqref{ab1} if ν admits the doubling properties sup0≤r<1∫21+r1ω(s)sds∫r1ω(s)sds<∞ and sup0≤r<1∫r1−K1−rω(s)sds∫r1ω(s)sds<∞ for some K>1. In addition, an analogous result for the one weight inequality ∥Pω(f)∥Dν,kp≤C∥f∥Lνp, where ∥f∥Dν,kpp=j=0∑k−1∣f(j)(0)∣p+∫D∣f(k)(z)∣p(1−∣z∣)kpν(z)dA(z)<∞,k∈N, is established. The inequality \eqref{ab1} is further studied by using the necessary condition Dp(ω,ν)<∞ in the case of the exponential type weights ν(r)=exp(−(1−rl)βα) and ω(r)=exp(−(1−rl)βα), where 0<α,α,l,l<∞ and 0<β,β≤1.
