The present research covers the time of the second rotation: sugar beet-spring wheat-pea-winter triticale (1999-02). The investigations were conducted on a very good rye complex soil. A reduced tillage for sugar beet and no-tillage for the other crops in crop rotation result in labour, fuel and energy consumption reduction, as compared with conventional tillage by an average of 50 percent and expenditure by 42 percent. The highest energy effectiveness in crop rotation was observed in the system in which sugar beet was cultivated in reduced tillage, and other crops in no-tillage. The effectiveness increases by 135 percent for conventional tillage for all the crops in rotation. The lowest effectiveness is obtained for conventional tillage with intercrop for sugar beet and pea, and conventional tillage for spring wheat and winter triticale
