We consider the $\ps$ production with transverse momenta which can not be explained by primordial motion of partons, $p_T>1.5$ GeV. It is shown that color octet contribution is dominant at these energies and reduces large dicrepancies between experimental data and color singlet model predictions. Having taken into account both contribution one needs a K-factor about 2-3 to explain the experimental data.Contribution to the III German -- Russian Workshop on Heavy Quark Physics, Dubna, Russia, May 20-22, 1996. 8 pages, LaTeX, 2 Postscript figuresHigh Energy Physics - Phenomenologytext
