The research was carried out in areas of production from Majibacoa Sugar Enterprise, Las Tunas province, to make an economic, energetics and environmental evaluation of technologies of weed control in spring cane plant, in a fluffed brown soil. In the experimental area, parcels were traced, according to a random blocks design with four replications. Nine technologies were evaluated, where the mechanical control and the chemist were combined with the manual cleaning, the animal traction and the mechanical cultivator was used and as means of application of herbicides, sprayer machine and backpack. To the different technologies it was determined economic utilities, energetic efficiency, loads pollutant towards the atmosphere and effects on the compaction of the soil through the resistance to the penetration. It was obtained that the most effective technologies were those which included the Isoxaflutole herbicide, where it was used smaller quantity of agricultural implements passes and applications of herbicides

Palabras clave : sugarcane; weed control; herbicides; environment; energy.
