In the article technological methods energy and economic evaluation of growing sage in southern steppe of Ukraine conditions have been analysed. The economists’ views on the raw medicinal herbs under drip irrigation formation of efficient production have been  considered. The analysis of previous agronomic studies on the cultivation of crops under drip irrigation has allowed us to conclude that there are no such results on the plantations of Salvia sclarea. The yield level of Salvia sclarea inflorescences was stable during the first three years of using, on the average in the first year it was 9.51 t/ha, in the second year it was 9.38 t/ha, in the third year it was 9.69 t/ha. Only in the fourth year of crops using (the fifth year of life) the yield was decreasing sharply. On the basis of yield data, the calculation and analysis of such indicators as energy efficiency, energy intensity of growing 1 kg of inflorescences and the conditional net profit when growing sage in drip irrigation in southern Ukraine. The maximum values of energy efficiency ratio were obtained in the first year of using and sowing in the first decade of December against the background of N60P90 - 3,25 application. When the crops sowing was postponed to the first decade of April, this indicator decreased twice to 1.59. In our experiment the minimum values of energy ratio of Salvia sclarea growing technology were obtained in the fourth year of plantation using. The classical indicators which reflect the economic and energy efficiency level   of inflorescences of nutmeg production at long-term use of a culture plantation culture have been analysed. The analysis of the factors which influence for efficiency change of cultivation of culture was carried out. The mechanism of efficiency increase of cultivation of sage nutmeg in the conditions of the southern Steppe of Ukraine has been offered.
