The effect of varieties (Fox, Zenith) and variants of soil tillage have been observed on both the yield and technological quality of sugar beet in the field multi-factorial experiment (A - hay harvest, stubble ploughing, farmyard manuring, mean ploughing, deep ploughing, evening of soil surface; B - hay harvest, stubble ploughing, green manuring, deep ploughing, evening of soil surface; C - stubble ploughing with incorporation of hay, green manuring, deep ploughing, evening of soil surface).
The highest root yield (65,52 t.ha-1) and polarised sugar yield (10,63 t.ha-1) was found on the variant B. The most significant digestion (16,46 °S) and refined sugar yield (14,27 %) was reached on variant C. In variety Zenith the highest yield of sugar beet roots (64,96 t.ha-1), digestion (16,51 °S), refined (14,43 %) and polarised sugar yields (9,93 t.ha-1) was found at given soil-climatic conditions.
