The p_T-spectra for direct J/psi and psi' in hadroproduction at Tevatronenergy have been calculated based on NRQCD formalism and fragmentationapproximation in the collinear parton model and k_T-factorization approach. Wehave described the CDF data and obtained a good agreement between thepredictions obtained in the parton model and k_T-factorization approach. Weperformed the calculations using the relevant leading order in alpha_s hardamplitudes and the equal values of the color-octet long-distance matrixelements for the both models.Comment: 10 pages, Latex, 4 eps figures, epsfig.sty, graphics.st
