We present the H-alpha flux measurements for 44 nearby dwarf galaxies, derived from the observations at the 6-m BTA telescope. H-alpha fluxes were used to determine the rate of integral star formation of galaxies, SFR. For the observed galaxies the value of log SFR lies in the range from 0 to -8 M_sun/yr. The specific star formation rate for all the sample galaxies does not exceed the limit of log SSFR=-9.2 yr^{-1}. A burst of star formation was detected in the center of a nearby dwarf galaxy UGC 2172.
