The field polyfactor experiment was founded at University farming bussines in Koliftany in 2004 - 2006. Valuated was the influence of decayed waste after production of biogas as organic fertilizer on production and quality of sugar beet. Variants of fertilization: 1. control variant (without fertilizer), 2. farmyard manure (25 t per ha), 3. decayed waste aplied on the soil at the autumn (50 t per ha), 4. farmyard manure (40 t per ha), 5. decayed waste aplied during vegetation (50 t per ha). The yield of roots sugar beet has been significant influenced by year, crop and fertilization. The highest average yield of dry matter sugar beet was at the variant decayed waste - during vegetation 50 t per ha (16.78 t per ha), farmyard manure 40 t per ha (13.39 t per ha) and decayed waste autumn (13.88 t per ha). The highest significant production of raffinate was available at the variant decayed waste spring (8.34 t per ha) and farmyard manure 40 t per ha (7.94 t per ha). The highest sugar content of bulbs (19.57 °S) was at the variant decayed waste - during vegetation 50 t per ha. Autumn application of the same dose of decayed waste 50 t per ha influenced possitively the majority of monitored parameters compared with unfertilization control. Existing results indicate, that decayed waste as organic fertilizer is comparable with farmyard manure.
