Hadronic production of $P$-wave charmonium states $��_{cJ}$ in hadronic interaction is considered. Using experimental results of CDF and LHCb collaborations we show, that contributions of color-singlet components are dominant. As for color-octet mechanism, we show, that contributions from $P$-wave states can also be observed, while $S$-wave states can be neglected. The best experimental observables that give information about relative importance of color-singlet and color-octet components are the ratios $��_{c2}/��_{c1}$ and $��_{c0}/��_{c1}$.<br/>14 pages, 6 figures, 2 tables<br/>
