Let 1 p < ∞. We show that p⊗F X, the Fremlin projective tensor product of p with a Banach lattice X, has the Radon-Nikodym property if and only if X has the Radon-Nikodym property; and that p⊗i X, the Wittstock injective tensor product of p with a Banach lattice X, has the Radon-Nikodym property if and only if X has the Radon-Nikodym property and each positive operator from p to X is compact, where
