We present new photoelectric UBV, photographic and visual observations of 29 selected symbiotic stars. The observations were made, with a few exceptions, in the years 1988 - 1990. The periodic light variations of UV Aur in the V colour are not related to orbital motion, but are connected rather with the Mira-like pulsation activity of its cool component. We have determined a new value of the period of about 365 days for these variations. Our visual observations allow us to propose a new ephemeris for T CrB. We have observed an outburst phase indication and a gradual increase in the value of the U-B index over the whole observational interval of BF Cyg. As for CH Cyg, we have observed a deep minimum in the V colour (≈9.2) followed by a rather strong increase in the U-filter (by ≈ 1.8 mag). We have accomplished the first optical photometric detection of the orbital motion within the CQ Dra (4 Dra) A + BC system. Our UBV light curves for AX Per have revealed for the first time evidence of an eclipse of the cool component by its hot companion. The data for PU Vul show a general decrease in all UBV colours since about JD 2447000, suggesting the occurrence of a new eclipse/obscuration event.
