The quantity of particular energy inputs in this analysis was obtained from the ratio of consumption of particular technical means and work force rendered in units of mass or time to respective energy indexes of unitary merged energy absorptiveness. The index of energy effectiveness was evaluated to be quotient of yield energy value from 1 ha to the value of energy input bore in order to obtain that yield. The calculation of energy effectiveness, calculated with the index of yield effectiveness of sugar beet out of objects of no nitrogen and biopreparates interference, indicates that the most profitable energy relations of yield value to production input occur at straw, green manure and phosphoric-potassic fertilizers. The introduction of nitrogen on conventional objects (A, B, C), resulted in the rise of effectiveness index to the dose of 100 kg/ha
