We consider the contribution to psi hadroproduction due to the elementary subprocess qq-bar..-->..psiGG. The color-singlet nature and observed spin-parity of the psi are incorporated and the normalization of the cross section is predicted by the psi wave function at the origin as measured in the leptonic psi decay. We expect this process to dominate the difference in psi production from particle versus antiparticle beams. The energy dependence of psi production as well as distributions in x/sub F/ and P/sub T/ are predicted.
