Abstract: Field trials were carried out on Balhihylogleyi-Calc(ar)ic Luvisol soils of the experimental station of the Lithuanian University of Agriculture. The aim of field trials was to estimate the influence of additional fertilization on sugar beetroot productivity. 'Ernestina' variety sugar beetroots were grown. At the stage of six paired leaves (BBCH 18-19) trial variants were additionally leaf-spray fertilized with Humicop solution, a solution of growth stimulator Penergetic-P and a solution of liquid complex fertilizers Atgaiva-P. Control variants were leaf-sprayed with water. The findings of the research revealed that additional leaf-spray fertilization with humic fertilizers Humicop resulted in by 4.5 t ha-1 or 7.4% significantly higher root productivity, significant increase in saccharinity by 0.07 percent units, and by 0.61 t ha-1 higher than in the control white sugar yield. Leaf-spray of the sugar beetroot seedlings with Penergetic-P solution resulted in significant sugar beetroot productivity increase by 8.8 t ha-1 or by 14.5%, and saccharinity increase by 0.31 percent units, and by 1.34 t ha-1 higher than in the control white sugar yield. Additional leaf-spray fertilization with the solutions of the liquid complex fertilizer Atgaiva-P resulted in significant sugar beetroot productivity increase by 11.5 t ha-1 or by 18.9%, and saccharinity increase by 0.91%, and by 2.13 t ha-1 or 27% higher than in the control white sugar yield
