The purpose of the research targeted on the influence of liquid organic fertilizer on the quality and harvest of fodder beet. For this purpose the experiment was organized under field conditions of Technology Experimental Station "Maximovca". As the material for the research was used variety of fodder beet seeds Ekkendorfskaya, worm compost and aqueous extract obtained from him. In experiment was used three lots (one - control, two - experimental). Fodder beet seeds were macerated in aqueous extract obtained from raw worms' compost, prepared in the ratio 1:100. The same extract was used as supplementary food administered in two rounds on experimental group I. Results of analysis demonstrated that biochemical indices of fodder beet in samples on experimental loads I and II outperformed, respectively with 33.97% and 19.62% - total nitrogen; 34.00% and 19.68% - raw protein; 6.73% and 1.78% - active acidity active acidity of plants on the witness lot. The content of nitrates in the experimental groups I and II decreased by 57.37% and 53.15% compared to the witness lot. Fodder beet harvest collected from experimental loads I and II was higher with 50.12% and 3.78% compared to that on the witness lot. Therefore, liquid organic fertilizer in proportion (water : worms' compost) 1:100, obtained from gross worms compost, has a positive impact on the quality and harvest of fodder beet.
