In modern conditions with the development and introduction of perspective technologies of corn cultivation it is important to decrease the material and energy expenses for unit of the area. In connection with it researches were carried out on the experimental plot of Stavropol State Agrarian University. The purpose of the researches is the reintensification of cultivation technologies of com hybrids for grain. The object of researches were technologies of various intensity: intensive biological, integrated, energy saving and extensive. For the valuing of an opportunity of reduction in energy expenses at cultivation of corn calculation of economic efficiency on an example of the average riped hybrid Newton, average riped RIK 345 and Krasnodar 382, contrastly differing on a level of responsiveness on change of agricultural background has been carried out. Having considered - the level of profitability-it is important to emphasize that the extensive and biological technology has the best result from the combined means in the hybrid RIK 345 — each spent ruble by the given variants has brought the profit in 1.54 rubles. Lower level of profitability on intensive technologyshows that additional investments on chemical posses the lower results in comparison with initial investments. The hybrid Newton is also the most profitable to cultivate by extensive technology and the hybrid Krasnodar 382 by the intergrated one. Thus, decisions on introduction of hybrids and technologies in concrete conditions should be based on carrying out of calculations on a complex of final economic parameters of a production efficiency. The reduction in energy inputs on cultivation of corn hybrids is quite justified from the point of view of their profitability
