Organomineral liquid fertilizer Avit 35 with morphoregulation and antistress effects favourably influence on the yield and sugar beet quality. After Avit 35 application in the 9th-10th leaf phase the root yield was increased by 14.6%, digestion by 1,4 deg S over water treated control. After wet autumn in the year 1998 the ash content was unsignificantly increased over control, whereas in dought year 2000 by decreasing of the ash content the refined sugar zield was expressivelz increased. In the average of years, Avit 35 have increased refined sugar yield by 29% over control. The joint application of Avit with herbicides (Lontrel, Betanal Progress, Gallant Super) was less optimal than the Avit application itself, mainly owing to digestion decrease. The refined sugar yield have increased by 9.2% over control after the Avit with herbicides mixture treatment. The joined application of Avit with the Agrovital adhesivum, which acts as antitranspirant, decrease the roots yield by 1.5% in the wet year, by 5.2% in the drought year under Avit itself application, but their quality too
