It is similar to the vase in the recent thread, "Lilac knobby vase - ID = Skrdlovice by Emanuel Beranek, pattern 5460," as attributed by Jindrich. 1954 would be the year of design for that vase mentioned above.
Your vase was certainly designed in the 50's at Skrdlovice and the colour would appear to confirm that it was produced then, though similar vases were produced for another thirty years or more. Several patterns from this time, the 1950's, are very similar and various Beraneks made very similar patterns of vases like this, most just attributed to Jan Beranek but several Beraneks made similar vases before he designed his famous pieces. Jan Beranek cannot claim to have originated this style of Skrdlovice vase, it was a family developed design style, involving various relatives, organically. Also the individual hand modelling at the furnace means slight differences can occur in any case. Specific attribution may take time, beyond it being certainly a 1950's Skrdlovice vase designed by a Beranek. Jindrich may more confidently comment in more detail but it looks to me slightly different from 5460 but very similar in terms of year and factory,
