We study the differential cross section of the single inclusive $e^+e^-$annihilation to the hadrons via $\gamma$-production, in the different${k_{t}}$-factorization frameworks. In order to take into account thetransverse momenta of the incoming partons, for the first time, we apply theKimber et al (KMR) method to calculate the unintegrated parton fragmentationfunctions (UFFs) from the ordinary integrated one, i.e., the partonfragmentation functions (FFs), which satisfy the similar DGLAP evolutionequations, such as those of parton distribution functions (PDFs). Also, byutilizing the different angular ordering constraints the results correspondingto the Martin et al (MRW) in the leading order (LO) and thenext-to-leading-order (NLO) are obtained. The LO sets of DSS library for theinput FFs is used. The numerical results are compared with the experimentaldata in the different energies which are reported by the differentcollaborations, such as TASSO, AMY, MARK II, CELLO, DELPHI, SLD, ALEPH andBelle with the other QCD+fragmentation models such as Pythia 6.4 and 8.2 partonshowers. The behaviors of the normalized differential cross sections and themultiplicity versus the "transverse momentum" ($p_\bot$) are discussed. Thefinal results demonstrate that the KMR and MRW UFFs give a good description ofdata and there is not much significant difference between the above threeschemes. On the other hand, our results become closer to the data for the lowervalues of $p_\bot$ and the higher values of center of mass energies.
