The problem of reasonable use of energy in modern production, particularly in agriculture, is still of vital importance. Just this circumstance makes us concider the technology of cultivation of sunflower from the point of view of effectiveness /recoupment/ of productive energy expeditures, accumulated in the harvested vield. In our view, this is a more stable index than the economic one, because of the flexibility of prices for material resources and the economic system typical for our days. A more exhaustive analysis has shown that there are real possibilities of reducing the energy expenditures for the technology of tillage. For instance, in the block of main preparation of soil-by 6.9%, fertilizers-by 7.2, pesticides-by 4.7% etc. Another considerable reserve for improvement of energy balance of production is the increase of energy accumulated volume owing to increase of sunflower yield.
