### Description

Using samples of 102 million $\Upsilon(1S)$ and 158 million $\Upsilon(2S)$ events and about 70 fb${}^{-1}$ of data taken in the nearby continuum with the Belle detector at the KEKB asymmetric-energy $e^+ e^-$ collider, we compare the inclusive production rates of baryons in 3-gluon vs. quark fragmentation processes. The spectra of $p$, $\Lambda$, $\Sigma$, $\Xi$, and $\Omega$ baryons are compared, and we quantify the enhanced production in 3-gluon mechanisms by studying their dependence on strange quark content. Experimental results are compared with Monte Carlo predictions.
